Abstract

The invention relates to an electronic marketplace for computerized continuous trading in products or services described by a predetermined number of product parameters, in particular a method for computerized trading in these products and a vending machine.

Description

The invention relates to an electronic marketplace for computerized accounts Nuclear trade in products and services by a pre certain number of product-specific parameters can be represented, in particular another a method and a vending machine for computerized trading with these products and services.

On the generic electronic marketplace, the products and Services through a predetermined number of product-specific para described in meters. These product-specific parameters are on the part of the Marketplace so that the individual products are comparable and are therefore tradable. Through the market place there is one product at a time standard or a product class defined by the product parameters.

This product standard set by the marketplace is with an industry standard or comparable to an ISO standard: With a standard, the number and type of Characteristics - for screws, for example, the diameter, the length, the Strength - and within the characteristics the number and gradation of the Aus embossing of these characteristics - the length and diameter gradations, the strength classes - binding. Screws with identical out embossing, i.e. with the same diameter and the same length as well as the have the same thread and the same material class, are independent of Her interchangeable. The generic system extends the principle on any products and services.

On an electronic marketplace, virtual market participants meet to get there Offering, trading and selling goods. The market participants can Place offers to buy or sell the goods in the marketplace Check existing offers and react to them with new offers. If if a market participant finally discovers an acceptable offer, he can accept and thus initiate a contract.  

In order to be able to create an open market situation, it is important on the one hand that none of the parties involved in a contract (buyer and ver buyer) is disadvantaged. On the other hand, as explained above, the products as far as standardized, that the offers in the market are comparable are.

For a computerized marketplace for electronic commerce, follow de Market models known.

A model, which is named in the following community model, works after Kind of a bulletin board. In the community model are certain Targeting buyers and providers who have industry-specific information a certain, selectable electronically via data communication lines your computer.

Another market model is the so-called catalog. With the catalog model is a large number of product data, including different suppliers, in one only so-called sales channel summarized and provided to enable buyers to compare offers. The sales channel is accessible again via data communication lines. Often there are Extended search functions for catalog customers are provided for catalog models. A disadvantage of the catalog model, however, is that the prices on the part of the providers fixed and there is no room for negotiation for the applicant or There is demand.

In the meantime, auction models are also available in the electronic marketplaces spreads. These models allow different buyers to compete to bid on products from certain sellers. The electro niche marketplace on which the auction module is implemented is also here accessible via data communication lines. Moved depending on the auction model the price just goes up or just goes down. All auction models however, it is common that there is no certainty for the seller that he his product is really auctioned and he gets a certain price. On  Another problem with auction models is that at the time of auction the Product required by the buyer is not necessarily offered in the auction.

Auction models are usually used when inconsistent Products, especially one-offs, are to be sold, the price of which from the seller due to a lack of comparison options with similar products, not be can be voted. Basically, an auction concerns a purchase or ver buying situation where one supplier has a large number of customers or users bern faces.

A typical auction model for an electronic marketplace trading in various types of non-standardized products are described in US Pat. No. 6,021,398 wrote. The auction model there is able to offer a purchase Plenty of buyers to match with a seller's offer to sell. The offers to buy and the offers to sell can be complicated rules for the dependencies between price, quantity and compilation of the ob include objects.

The disadvantage of this system is that an auction is a one-off event is that takes place on a specific auction date. At an auction you can the buyer also does not expect to have the auctioned goods gets a certain price.

The auction model of US 6,021,398 also does not take all of them into account che, a sales offer or a purchase offer underlying In addition, the auction model of US 6,021,398 only takes one Auction situation with only one provider, but no trading situation with one Variety of providers and a variety of applicants.

The present invention is therefore based on the object of providing security for market participants to increase the products on the electronic marketplace to actually be able to buy or sell. In addition, the invention is the Task based on the costs arising from such transactions between between market participants more realistically.  

This object is achieved according to the invention for an electronic marketplace of the type mentioned at the outset by a method for automatic trading with products and services described on a virtual marketplace using a predetermined number of product parameters, using a trading machine, comprising the following method steps:

• - Receiving at least one digital order with order parameters from at least one market provider via digital data communication interface at the vending machines;
• - Receive at least one digital market test request with market test parameters from a market competitor via a digital data communication nicification interface at the vending machines;
• - Automatic change of at least a subset of the order parameters and / or the market review parameter as a function of the respective order dependent market provider-market candidate pairing by the commercial car maten;

and

• - Sending at least the changed order parameters and / or market review development parameters in electronic form via digital data communication interface to the market competitor.

The object is also achieved by a vending machine for computerized trading with products and services described by a predetermined number of product parameters on a virtual marketplace, comprising

• - At least one data communication interface through which the trade automate at least one digital order with order parameters of min at least one market provider and at least one digital market test Inquiry with market test parameters from at least one market applicant are electronically feedable;  
• - An electronic, software-controlled core module with a parameter core rectification module to which the order parameters and / or the market review para meters, and through which at least a subset of the order pa parameters and / or the market test parameters as a function of the respective Market provider-market candidate pairing is changeable,

and

• A means for outputting at least the changed order parameters and / or market test parameters in digital form via the digital data communication interface to the market candidate.

The method according to the invention and the vending machine according to the invention are intended to provide an electronic marketplace for continuous trading len. Unlike an auction, this means that, like an exchange, Offers are constantly made available by the marketplace and contracts are always on completed due to matching offers and counter-offers can be. The marketplace according to the invention thus bears the needs commercial customers' bills that are not only valid at the time of an auction, but at a time when there is a need for a product, theirs Have to satisfy demand.

According to the invention, the electronic marketplace is operated by a commercial car maten, for example, an electronic, software-controlled device, which without human intervention the offers complementary counterparts messengers.

The vending machine receives a plurality of orders at least one Market provider, the sales offers or purchase offers with order parameters tern, the order-specific parameters, such as the quantity and price of the products, and product specific features, d. H. the characteristics and characteristics of the Products in the standard prescribed by the market place, price included.  

The vending machine continues to receive a market inspection order, the market includes order and product-specific parameters.

The vending machine automatically corresponds to the market review order appropriate offers to the market competitor that he can process.

An essential point of the invention is now the order parameters and / or the market review parameters depending on the particular market change provider-market candidate pairing. This means the following: Between a certain market provider and a certain market competitor about, d. H. a market provider-market candidate pairing, certain changes there are interactions that are only present in this pairing and on the other hand influence the order parameters.

For example, between the market provider and the market applicant Rebate agreements are in place, so in this case the discount, for example, a quantity or price discount must be taken into account. On Another example are transportation costs, which vary depending on the status can change locations of the market provider and the market applicant. This too Costs must be taken into account in the offer.

However, this is not yet known when the market provider creates the order is with which market competitors a contract is ultimately concluded they can depend on the market provider-market candidate pairing A priori costs cannot be determined.

According to the invention it is therefore provided that the vending machine is the one of the Market provider-market candidate pairing dependent order or market review parameters and changes them as if the market provider a priori knowledge of the market applicant who sent the market review order has had. Usually only a part of all order pairs meter dependence on the market provider-market candidate pairing sen. The vending machine automatically changes these parameters without human influence, from.  

The solution according to the invention has the advantage that the market competitor can view the changed order parameters. Security is at signing a contract for both parties is significantly increased because after the conclusion of the contract both sides with no more changes to the order parameters have to calculate. The trade is therefore completely via the vending machine can be processed because all order parameters are realistically recorded.

An essential aspect of the invention is the consideration of the Transfer costs represent: For a variety of products, such as screws, Metal rings and other machine elements are the transfer costs involved in the Transfer of the products from the seller to the buyer no longer arise negligible. The transfer costs include, for example, the freight and Shipping costs and customs duties. In addition, the transfer costs are from the respective locations of the seller and the buyer, i.e. the individual pairing depending on buyer and seller.

In an electronic marketplace, the buyer goes to create his Purchase offers from a price that already includes the delivery of the goods holds ("free house" price). In previous electronic marketplaces, the Buyers only receive the offers of the sellers with the prices "ex works" and had no information about the transfers added to these prices costs. Consequently, in the conventional electronic marketplaces, the Conclusion of the contract depends essentially on the transfer costs, which these prices still would have to be added. So far, it was an efficient contract not possible. So far, the conclusion of the contract had to be bilaterally agreed.

Similarly, when creating a sales offer, a seller assumes that its stated price is an "ex-works" price in which the freight cost are not yet included. The seller knows at the time of creation not even the potential buyer of his sales offer Location ultimately depend on the transfer costs. Therefore occurs as a market competitor a buyer, in a further advantageous embodiment, the price the complementary sales offers of the market providers the transfer costs  be added. If a buyer appears as a market provider, the Vending machines in a further advantageous embodiment of the prices the transfer costs are deducted from the complementary purchase offers.

Due to the advantageous automatic consideration of the transfer costs the vending machines are the opposite of each other in the match offers, the transfer costs incurred due to the individual buyer's Seller pairing arise, incorporated into the offers.

The buyer can see the free house price in his match result all transfer costs are included.

Thus, the electronic marketplace according to the invention offers regardless of Location of the seller and the buyer the possibility already in the contract to complete the transfer costs of the individual buyer-seller pairing take into account.

The transfer costs are in an advantageous training on a storage space stored in a transfer cost database in the vending machine and readable from there by a reading unit from the vending machine.

In a further advantageous embodiment, the trading machine calculates auto matically the product-specific transfer costs, d. H. the transfer costs by the product characteristics such as product volume, product quantity and insurance depend on the costs. In this case, the transfer cost database can be used as Transfer cost information an assignment for example of the weights and the Volume of the various products on a per piece basis at the transfer costs Dependence on the start and end points as well as the course of the trans portweges be saved. When calculating on a per piece basis, it can be advantageous the vending machine may have a multiplication unit by the total to calculate costs depending on the respective order quantities.

In a further advantageous embodiment, the Vending machine also provides the transfer cost information in digital form via a  Automatically request data communication interface from a service provider and received. This reduces the maintenance costs for the trade automated, since the maintenance of the database is not necessary.

In a further advantageous embodiment, the transfer costs can also customs duties are taken into account in order to calculate the actual Chen order price. The tariffs can be in a further out design can also be stored in a database in the vending machine. he vending machine can apply the tariffs applicable at the time of a market review query from an external system via the data communication interface.

In a further advantageous embodiment, the vending machine also leads at least one automatic and electronic parameter comparison Subset of the order parameters with a corresponding subset of the Market check parameters automatically through the vending machine. By this comparison, the vending machine can match the order Determine parameters with the market test parameters. The change in on wearing parameters depending on the respective market competitor-market provider Pairing can take place before or after the parameter comparison.

However, when comparing parameters, the dependence on the respective market already considering applicant-market provider pairing, it is advantageous if, in a further embodiment, the vending machine has the automatic change changes the order parameters before the parameter comparison.

In a further advantageous embodiment, the vending machine can use the language surface of the comparator output via the data communication interface result depending on at least a subset of the market review pa parameters and / or in the vending machine for the respective market competitor stored information by querying a vorese in the vending machine automatically set the language database of the vending machine. At the This configuration is from the commercial machine to the market competitor sent information about complementary offers from market providers in one language selected by the market competitor. This configuration enables  the international application of the method according to the invention and of the vending machine according to the invention. The speech representations that the Market participants in, for example, a graphical user interface for loading condition of the vending machine and implementation of the procedure via the Da Communication line can be provided in a wide range ren design be standardized and dependent on a database from the attitudes of market participants from a reading unit of the trade be readable automatically.

The different market participants with an international marketplace different currencies can work in another advantageous way design be provided that the order information of the orders of Market provider in one of the market applicants in its market review parameters or in other parameters stored in the vending machine Currency can be specified. The auto conversion takes care of the conversion through matically. To take the current daily exchange rate into account when converting vending machine via the data communication interface An Ask questions to an external currency machine and from it the current ellen course received.

The vending machine enables in a further advantageous embodiment also the specification of positive or negative lists, so that a market participant the possibility is given with certain market participants in the positive list prefers to do business or with certain market participants in the Negative list not to conclude contracts.

In a further advantageous embodiment, the vending machine can frame Accept orders and process them from a given time periodically recurring, identical individual orders exist. The This design enables market participants to be available at all times to meet the need.

In a further advantageous embodiment, the vending machine can be used for one Purchase order from a market provider, a percentage contained in the order parameters  Consider matching coverage. This means that the Han delsautomat when comparing the one to the market test parameters Market inspection order matching order parameters of a complementary Order takes account of a parameter range, for example a price deviation that is seen as a one- or two-sided percentage deviation from one preferred mean, for example the desired price, is given. Thus, when creating the matching proposal from the retail machine Offers are also taken into account, the parameters of which are not exactly the same Market test parameters correspond.

In a further advantageous embodiment, the vending machine can Quantity-dependent price when looking for suitable complementary offers messengers are used. This quantity-dependent price can be determined be that in the order parameters and / or the market review parameters a plurality of product quantity-unit price pairs are included. Based This data enables the vending machine to compare parameters according to an inter polishing of the product quantity-unit price pairs and creation of a price Perform quantity function.

After the market competitor automatically receives a matching Proposal has been made, the market competitor may appear interesting to him Orders from market providers with a new market review with changed ones Market test parameters react, to which the vending machine automatically works created a new matching proposal. This process continues until the Market applicant decides to accept an offer. In this case, a sent the signal indicating the conclusion of the contract to the vending machine. In The Han enables a further advantageous embodiment of the method automatic and electronic payment processing according to Ab conclusion of a contract between two market participants. Again this can be done the data communication interface via which the vending machine Exchange messages with external payment institutions and payment of the Market candidate to the market provider can make perfect.  

In a further advantageous embodiment, the vending machine can open the door the contract for which a contract was concluded, automatically to the extent the contract covers. This ensures that there are no duplicates Sales of the same thing take place. If only a part of the ent quantity of product sold or bought, only this part remains deletes. The remaining part remains available through market test orders.

In a further advantageous embodiment, the vending machine can open the door store sluggishly in an order database after receipt. From there are the up sluggishly readable immediately using a reading unit to make a matching comparison create.

A problem with conventional methods for computerized trade or With vending machines arises when a single order, this can be an order from a market provider or a market review order from a market applicant, not from a single one, but only from a plurality of complementary ones Orders is matched.

The method according to the invention and that he sees to solve this problem Vending machines according to the invention in an advantageous embodiment, ei Several market completing a market review order from a market applicant Messenger of one or more market providers, preferably through a linear or non-linear optimization, automatically assign. This has the advantage that also large order quantities that do not have the same large complementary order contracted amount, can be traded. In this case, collect the vending machine automatically several, according to predetermined or adjustable Compiled orders optimized according to their criteria, with a smaller order volume to match the large amount of orders.

In a further embodiment it can be provided that the Han delsautomat originally received separately from a market provider other independent individual orders for a bulk or envelope order auto summarized mathematically. The vending machine can provide this summary  depending on the market inspection order according to a cost function count.

The vending machine according to the invention can be in a further embodiment Have evaluation module that on the marketplace for individual versions achieved prices by calculating the price of all traded pro products calculated as a function of a certain product parameter. This is just in the standardized description of the products via a predetermined type number of product parameters possible.

Before going on to depict the structure and function of the inventor electronic marketplace in accordance with the invention should initially the terms used are explained. These terms are based on the terms common on stock exchanges.

Thus, as a "market participant" all registered users of the electronic Marketplace understood. Market participants can take the role of a buyer or a seller, with a single operator both can act as a buyer as well as a seller. Regardless of the buyer Every market participant can act as a seller in the role of a "market provider" or a "market applicant". In the role of the market provider, the Market participants make a (buy or sell) offer to the electronic marketplace offered. In the role of the market candidate, he observes the right for him relevant market offers and concludes a contract with a Market provider.

An "order", also called a "bundle", is the offer of a market participant, to buy or sell a certain number of products. A sale order consists of a number of order items or orders. Every up carrying position defines for a certain product, within which period, how long and in what quantity the market participant delivers a product wants to sell. The same applies to purchase orders.  

A "blanket order" corresponds to a set of periodically recurring ones Orders. The individual orders that form the outline order are up to identical to the delivery date.

Under a "private area" one becomes invisible to the other market participants understandable area. In the private sector, every market participant can to prepare his orders.

If the market participant makes his offer for market created in the private sector keeps it ripe, he can transfer it to the "public area", where it is for everyone Market participants are visible. With the transfer to the public area can every market competitor take advantage of the offer.

A "market check" here means the automatic check of an offer against the market, d. H. the amount of public area offers available for the market participant with regard to the criteria he chose on the güns most are understood by the vending machine.

A proposal made by the electronic marketplace that offers the in the market test meet the criteria is called "matching proposal ". Finally, the market candidate decided to go for a market decided, the corresponding matching suggestion becomes a "match".

The "portfolio" is the quantity of all orders and order items in a market participant understood. It includes all orders in private and in public Area.

After all, the "marketplace" is the set of all orders and associated orders supporting positions of all market participants in the public sector.

In the following the method according to the invention for computerized trading with these products and the vending machine according to the invention with the aid Taking the drawing explained.

Fig. 7 shows an example of the automatic calculation of the transfer costs by trading machine at a buyers market as candidates.

First, the structure of the electronic marketplace according to the invention described.

Fig. 1 shows an indefinite number of systems 1.1 to 1 .n of market participants, in total n = 1, 2 ,. , , Market participants, whereby a system can also be assigned to several market participants and a market participant to several systems. In Fig. 1 are shown as Marktteilnehmer- or user systems by way of example computer systems. The user systems 1.1 to 1 .n are each connected to a communication system 3 via a data communication line 2.1 to 2 .n. The communication system 3 can be any digital communication system that allows data transfer in both directions. The communication system 3 can be based on a wide variety of standards and a modem connection, a connection based on communication protocols such as WAP, TCP / IP, CORBA etc., generally an Internet connection, or a Datex-P connection, a LAN or WAN Network etc. or any combination of these connections.

A vending machine 10 is connected to the communication system 3 via a data communication line 7 . The vending machine 10 generates the virtual electronic marketplace and can be formed by any electronic device. In Fig. 1, the electronic marketplace 10 is shown schematically by a computer. However, the electronic marketplace can also be distributed over a large number of computer systems. The vending machine 10 allows simultaneous use by any number n of user systems 1 .

In FIG. 2, the internal structure is a user system 20 and the commercial machine 10 shown schematically.

Via a user interface 11 , data can be entered directly into the trading machine 10 by a user. This can be useful, for example, for system administration of the vending machine 10 . The user interface 11 can be designed as a screen with a keyboard, as a floppy disk drive, as a CD-ROM drive, etc.

The vending machine 10 also has a digital communication interface 12 , via which the vending machine 10 can exchange data with other systems connected to the communication system 3 , for example user systems, other exchange systems, debt collection systems etc. Several communication interfaces 12 can also be provided. The communication interface 22 can send data to the communication system 3 and receive data from the communication system 3 .

The vending machine 10 furthermore has a main processor, on which the method for trading on the electronic trading place essentially runs. A CPU 13 is shown in FIG. 2 as the main processor. Any number of CPUs can also serve as the main processor. By the CPU 23 who processed the instructions that are stored in a memory 24 . The user interface 11 , the communication interface 12 , the CPU 13 and the memory 14 are connected to one another via a data bus of the commercial machine 10 . The data bus can be an internal data bus or, in the case of a distributed system, a network.

The memory 14 has a section in which an operating system 15 is stored. The operating system 15 controls basic operations of the vending machine 10 , such as the input and output of data, access to peripheral devices, prioritization of processes that run on the CPU 13 , etc. The memory 14 also has an area 15 in which one or more executable programs are stored which can run on the CPU 13 . Furthermore, part of the memory is provided with data 16 with which the operating system 15 or the program 16 work. The memory 14 can consist entirely or in part of a memory with read access only or in whole or in part only from a memory with read and write access. CD-ROMs, hard drives, other computers etc. can also be used as the memory 24 .

As can also be seen in FIG. 2, a user system 20 , corresponding to one of the user systems 1.1 to 1 .n in FIG. 1, is constructed analogously to the trading system 10 .

Fig. 3 shows schematically the interaction between the Handelsautoma ten 10 and a user system 20th A user program 101 runs locally on the user system 20 and exchanges data with a user process 102 via the data communication line 2 and the data communication system 3 . The user program 101 represents the interface via which a market participant interacts with the vending machine 10 . On the part of the vending machine 10 , a communication process 102 is running, which receives the data sent by the user system, the “market participant”, and forwards it to internal processes for further processing. In the vending machine 10 there are also a number of databases 103 in which data are stored. This data is used to further process the data sent by the market participant to the vending machine 10 , for example an order or a market inspection order. A part 104 of the databases can also be outsourced and automatically provided by external systems 105 at the request of the vending machine.

Fig. 4 shows the functional division of the vending machine 10 , as it is realized by the various programs stored in the memory 14 and executed by the CPU 13 th programs.

The electronic marketplace 10 includes a core system 110 that performs the essential functions of the vending machine to create the electronic marketplace, such as receiving orders and market review orders, processing the order parameters, and creating and sending matching suggestions.

The core system includes a transfer cost module 112 , by means of which the transfer costs are calculated and the order parameters are changed depending on the respective market applicant-market provider pairing. For this purpose, the transfer cost module has arithmetic units such as multiplication units, adders or units, integrators and interpolation units.

The core system 110 further includes a comparator 114 , which compares the order parameters of an order from a market provider with the market review parameters of a market provider and provides a comparison result in digital form. The comparator can also include arithmetic units, in order to be able to carry out comparisons between parameters which themselves do not represent an exact value, but rather represent a function defined over a range of values.

The core system 110 also comprises a generator 115 , to which the comparison result of the comparator 114 is forwarded and which creates a matching proposal from the comparison result. For this purpose, the generator 115 also has arithmetic units in order to carry out an evaluation and weighting of the individual orders contained in the matching proposal as a function of the market test parameters or the order parameters.

Finally, the core system 110 also comprises a plurality of databases 117 , in which information is stored, which the vending machine 10 automatically accesses when the matching proposal is created. These databases 117 include an order database 118, in which are currently in force, the Han 10 received orders dels machines from market vendors with their job stored parameters, a product database 119, which are hedged vomit in the produktspezi specific parameters of tradable with the trade machine products. Under the databases 117 there is also a user database 120 in which user-specific information about the market participants operating on the trading machines is stored. In addition, a transfer cost database 121 is provided, in which information about the transfer costs for moving the products from one place to another is stored.

The databases 117 are usually not visible to the market participants in their entirety.

The vending machine 10 also has an administration module 125 , an accounting module 126 , a payment module 127 , a voice module 128 and a currency module 129 , which are briefly described below:

The management module 125 is used for the maintenance and care of the vending machine 10 and permits interventions in the modules 110 to 129 of the vending machine 10 by the operator of the electronic marketplace.

In the electronic marketplace 10, an accounting module 126 may be included, which automatically executes the accounting over the electronic marketplace 10 for the Operator Op. The accounting module 126 monitors the orders received from the market providers and the market review orders from the market applicants as well as the contracts concluded between market providers and market applicants. Based on this information, the accounting module automatically creates fee invoices for market participants, which can then be processed automatically via the payment module.

Via the payment module 127 , the payment can be processed automatically when a purchase contract between a buyer and a seller is successfully concluded. For this purpose, the payment module 127 is connected via a data communication line, not shown in FIG. 3, to an external collection system, for example a credit institution 130 . Through the data exchange with the credit institution 130 , money transfers between market participants or market participants at the trading machines can be carried out automatically by the trading machine 10 .

In order to be able to use the electronic marketplace 10 internationally in a large number of countries and to take into account that buyers and sellers do not have to be located in the same countries, the electronic marketplace 10 has a language module 128 and a currency module 129 .

The language module 128 is equipped with a language database 128 a, in which the various languages are stored, with which the user program 101 , cf. Fig. 3, representing the data received from commercial machine 10 data.

The currency module 129 takes into account different currencies on behalf of a market provider and the market applicant's market review request. The vending machine automatically determines these differences by comparing the market test parameters and the order parameters and activates the currency module in order to convert the currencies to the currency specified in the market test order. For this purpose, the currency module can be connected to an external system 131 , for example a currency exchange, which forwards the exchange rates to the vending machines continuously or on request via a data communication line.

In the following, the function of the electronic marketplace is described using Be usage examples described.

Before a user can participate in the electronic marketplace as a market participant, he must register as a new user in the vending machine. The registration preferably takes place automatically via the data communication line 2 . The new user dials into the vending machine via the data communication line and provides information about his identification, his location and his contact. The new user data are automatically entered into the user database 120 by the core system. The authenticity and quality of the registering users can be checked and individual users can be prevented from accessing the vending machine via the management module 125 . The vending machine 10 automatically creates identification data such as passwords and user IDs for the user identification.

After the registration is completed, the vending machine notifies the new one User through the data communication line through the successful registration tion.

To secure data exchange between the user system 20 and the commercial machine 10 to ensure the trade machine can 10 for data transmission an encryption module (not shown) used by the exchanged information is not made available to third parties.

In order to be able to participate in the market, the registered user dials into the vending machine via his user program 101 and enters his identification and his password there. If the identifier and password match the identifier and password stored in the user database, the core system 110 enables the user access to the electronic marketplace.

With the access authorization, the user can change his user-specific at any time change data. These user-specific data include the user-identifying information including order-specific data or parameters, specify the individual criteria to be taken into account for orders. These criteria rien correspond to the presettings for later orders.

The order-specific parameters include, for example:

• - the minimum weight per order in order to be able to ship the purchased o prevent the sold goods from being sold in too small quantities;  
• - the minimum rating of the contractual partner with regard to product, delivery, Payment and packaging quality;
• - the minimum matching coverage of an order in terms of price, Quantity and number of products delivered in percent;
• - the identifier of market participants with whom he has no contract wants to do (negative list) or with whom he prefers to conclude contracts wants to eat (positive list), whereby each market participant is a member of his own Negative list is to avoid matching with your own orders the; and
• - the preferred currency and language of market participants mers.

The function of the commercial machine 10 is shown schematically in FIG. 5. The order parameters of orders - purchase offers or sales offers - of individual market providers 20 are stored in the order database 119 .

The creation of an order takes place in the private area of the market participant on the user system 20 or in the vending machine 10 , without another market participant being able to see the order creation process. The private area may be physically located on user system 20 , on the trading venue, or on any other system.

To create his order, a user enters the product-specific order parameters by which the product is described on his user system 20 via the user interface 21 and the order-specific or order-specific order parameters, for example the number of desired products, the desired price and the delivery date.

An important aspect of the vending machine according to the invention is the ability of the market provider to generate orders that are out of focus. Various products, each with a finite number of product parameters, are described in the product database 119 . For screws, these product parameters include size, material class, surface treatment and color. These product parameters can be determined in the market test parameters either exactly, by specifying the desired parameter, or unsharp, by specifying a parameter range or several characteristics. If a characteristic of the product parameters, for example the color, is completely uninteresting for the market competitor, he can leave it as a "wild card" completely indefinite. An order with a subset of product parameters specified or released in certain areas is referred to as a fuzzy order.

Finally, the user has to specify how long his order is valid should. The vending machine only considers orders within the order validity period of activity. Before the start or after the validity period expires, the Han delsautomat the orders for market inspection orders are not available.

A blanket order can be created in the same way as a single order become. To do this, the user must also specify when the frame order to be executed for the first time, how many individual orders and in the distance between these individual orders. Because the single orders of a blanket order are identical, if the Individual order all associated individual orders changed at the same time.

The vending machine also allows the indication of quantity-dependent prices. For example, a different unit price can be specified for a minimum quantity and for a maximum quantity. The core module then interpolates between these two limit values to produce a price function depending on the order quantity. In this case, the matching proposal is calculated by vending machines based on the interpolated price. The core system 110 also accepts a plurality of unit price-quantity pairs and automatically selects an appropriate interpolation function depending on the number of price-quantity pairs.

After specifying all the job parameters, the user can decide whether he should the order in the public area on the order database by the  Vending machines provide controlled access from market competitors wants, or whether he ge the order just created as part of a market review wants to test the orders in the order database.

If the market participant decides to publish his order, he generates an order signal on his user system 20 by actuating a switching element. Upon the order signal, the vending machine 10 automatically takes the offer of the market participant from their private area and stores it in the order database 118 . In order to enable quick access to the database 118 , the vending machine 10 can automatically process and convert the order into the database format before it is stored in the database.

If the market participant decides to carry out a market test, he generates a market test signal on his user system 20 by actuating a switching element. The vending machine 10 tests the created order against the market in response to the market check signal. The market is formed by the currently valid orders stored in the order database. The market test forms the main function of the vending machine 10 and can be carried out by the vending machine 10 for an order in the public or private sector.

The process of the market check will now be described with reference to FIG. 5.

The vending machine 10 receives, via its communication interface 12 connected to the communication system 3 , a market test order 150 which is in digital, electronic form. The market test application contains order-specific parameters 151 and product-specific parameters 152 .

The vending machine 10 can perform market review orders from a variety of product classes, such as bolts and nuts. The core system automatically determines the product class within which the market review is to take place based on the product-specific parameters 152 .

Once the product class has been determined, the core system 110 can initially carry out a rough search in the order database in order to carry out a first rough selection based on a subset of the order and product-specific parameters of complementary offers. For this purpose, the comparator module 112 can be preceded by a comparator with an arithmetic unit (not shown) which has access to the job database via a reading unit.

The transfer cost module 112 calculates the transfer costs as a function of the market provider-market applicant pairing and the or- and product-specific parameters 151 , 152 .

For this purpose, the transfer cost module 112 reads information about the product-specific transfer costs from the product database 119 . This is, for example, the unit weight and the packaging volume of the products contained in the market inspection order. Furthermore, the transfer cost module 112 reads information about the location and the preferences of the market applicant and the market provider from the user database 120 . For example, user preferences may include certain shipping method requirements. With the information about the user-specific and the product-specific transfer costs, the transfer cost module 112 automatically calculates the transfer costs with the aid of the transfer cost database 121 . The transfer cost module 112 automatically takes into account the order-specific parameters such as the order quantity.

With the help of an integrated arithmetic unit, the transfer cost module 112 calculates the transfer costs 153 for the individual order and the individual market provider-market applicant pairing and changes the order price accordingly in the order parameters. The order parameters 153 and the product parameters 152 changed by the transfer costs are then forwarded to the comparator 114 in digital form.

The comparator 114 uses an arithmetic unit to compare the at least partially changed order parameters 153 with the order-specific market check parameters 151 . The comparator 114 automatically filters out the matching complementary market offers as a function of the order-specific parameters. The comparator automatically takes into account imprecise offers, quantity-dependent prices and overlaps specified in the order and market test parameters. As a result, generator 114 sends an electronic list 154 to generator 116 .

The generator 116 organizes the electronic list generated by the comparator 114 and generates a matching proposal 155 , which it sends to the market applicant's user system in digital form.

The generator 116 calculates, depending on order-specific parameters and information from the user database 120, a list order in which the list 154 generated by the comparator 114 is sent to the user system 20 . For this purpose, the generator can also be physically located in the user system 20 . The generator uses an optimization function to calculate the sequence.

The market applicant can have the matching proposal 155 listed on the user system 20 and compare it with his order. If he finds a suitable offer, he can initiate a contract. Otherwise, he can observe the market situation for all displayed offers from the perspective of the market provider in order to be able to react accordingly to the competition.

The market applicant can then carry out a new market test with changed market test parameters in order to search for other orders which were not found during the first market test. The renewed market check then runs again according to the scheme described in FIG. 5.

In the automatic market check, the market applicant can control the selection of the offers stored in the vending machine by changing his market check criteria. For example:

• - an accepted deviation of the offer from the desired price,
• - compliance with the desired minimum weight and / or  
• - specify a deviation from the negative list, d. H. whether also offers to be displayed by market participants who are on the negative list of the market candidate.

This means that a matching proposal that has already been created can be processed further the and the complementary orders found according to other rules evaluated and listed.

By specifying the market review parameters, the market applicant can choose whether the selection of offers should be optimized according to the number of order items, price, weight or quantity. The user system then lists all offers that have an overlap with the current order of the market candidate in the desired order on a screen or prints this list. It shows the following order parameters:

• - Number of order items, number of items and weight of the coverage (in each case absolutely and relatively related to the current order of the evaluator bers),
• - Proportion of the cost of the surplus arising from the claim of the provider taking into account transport and customs costs (absolute and relative to the current job of the applicant),
• - Proportion of the cost of the surplus arising from the current order of the Provider arise (absolute and relative to the current order of the applicant) and
• - customs and transport costs.

All of these parameters are displayed from the perspective of the market applicant.

Incorporated Figs. 6 and 7 illustrate how the transfer costs in the matching proposal. The calculation of the sales price depends on whether the current order is a buy or a sale. For simplicity, the example is limited to a single order item. If there are several order items, the individual orders are included in the calculation based on their total share.

In FIG. 6, the following situation is depicted: A seller wants to sell 200 a lot of screws, which is assumed to be 100%, for a total price of $ 1000 from the factory. With this market review request, the vending machine searches for complementary buy orders in the order database 118 . In the order database there are two purchase offers, 201 and 202 , of which one buyer 201 wants to buy a relative amount of 50% of the products sold by seller 200 free of charge for a total price of $ 570. The other buyer 202 wants 40% of the quantity offered by seller 200 free for a price of $ 450. Without taking the transfer costs into account, the free house purchase offer of buyer 201 is therefore greater than that of buyer 202 .

Trading Machine calculated for the pairing of the buyer 201 to the United buyer 200 the total transfer cost of transporting the goods from the seller to the buyer 200 201 to $ 80. These costs must be deducted from buyer's 201 home offer to be compared to seller 200's sale offer.

For the pairing of the buyer 202 with the seller 200 , the trading machine calculates the total transfer cost at $ 50. As with buyer 201 , transfer costs are deducted from buyer 202's purchase offer. Taking the transportation costs into account, this results in a purchase offer price of $ 400. The purchase offer of the buyer 201 therefore corresponds to the sales offer of the seller 200 for the quantity sought by the buyer 201 , taking into account the transfer costs. The vending machine 10 will therefore include the purchase offer of the buyer 201 in the automatically created matching proposal.

Since the transfer costs depend on the respective buyer-seller pairing, for another seller 203 with different sales parameters, for example a price of $ 900 for 100%, the offer of buyer 201 may be more attractive with regard to the prices adjusted for the transfer costs prove.

FIG. 7 shows a case example analogous to the case example of FIG. 6, in which a purchase demand is to be matched by the commercial machine as a market check request: buyer 205 searches for a quantity of 100% free of charge for a total price of $ 1000. In response to this market test request, the vending machine 10 searches in its order database 118 for offers that match the product test-specific parameters with the market test demand. The vending machine finds the sales offers from sellers 206 and 207 . Seller 206 offers 50% of the quantity requested by buyer 205 ex-factory at a price of $ 600. Seller 207 offers 60% of the quantity requested by buyer 205 ex works at a price of $ 670.

For the automatic creation of the matching proposal, the transfer cost module first calculates the transfer costs for the two pairings buyer 205-seller 206 and buyer 205 to seller 206 at $ 70 and $ 80, respectively. These costs must be added to the ex-works offers of sellers 206 and 207 before the vending machine optimizes the offers for the market test order with regard to their prices. After taking the transfer costs into account, both sales offers are above the price sought by buyer 205 .

The vending machine will evaluate the offers of buyers 206 and 207 according to a cost function, for example the deviation from the desired unit price of buyer 205 , and send them to the system of buyer 205 in the order evaluated.

Decisive for the automatic evaluation of the order in the optimization according to the price, as it is carried out by the vending machine, is the diffe difference between the desired price and the offer price based on the Total price of the coverage.

The current order is against all offers (i.e. orders) in the marketplace checks where there is an overlap of delivery times between the current order and the offer there. In the case of fuzzy purchase orders, the Han leads automatic blurred matching by: order items in which the Buyer multiple occurrences or a range for a product-specific  The parameters of an article are selected by the vending machine with all Sales orders matched with one of these characteristics.

It can happen that several offers of the same one occur in the market review Market participants are displayed. This can lead to the maximum possible scope of matching between the participating market participants does not he is enough because matching can only take place on an order basis. To this situ The market test algorithm tries to limit the limit as far as possible After determining the matching candidates, orders from the same provider summarized in a (virtual) collective order by the individual Order items of the orders involved are added up. It is to be make sure that the delivery time overlaps and the excess requested by the buyer cover volumes for the matching are observed. There are various Heuristics possible.

To get an overview of how the current order in the Be the market owner can draw on a specific order from a market provider advertise a market review with the order parameters of a matching Execute the proposal contained in the proposal. The market competitor slips in the role of the complementary market provider. The vending machine creates too this market check request automatically a matching proposal, as above has already been described. In this complementary matching proposal are for the complementary offer to the original market review request all possible matching candidates are shown, who are for the corresponding An bid are currently in the marketplace.

This result corresponds exactly to the view that the market provider has on the market review of his order would be received. So every market participant has the opportunity before entering into a contract or rejecting an offer adjust his order according to the market situation.

When the competitor finally finds an acceptable offer, he can send the transaction signal to the vending machine Make trading perfect. In this case one speaks of a match. After that  the overlaps from the orders involved in the order data bank extracted and the reduced orders in the respective portfolio of the market participant taken over.

A blanket order can only be matched with another blanket order (or be included in the list of suggestions). The prerequisite for this is that Start time and number and frequency of repetitions of the two frames orders match. In order to be able to comply with these restrictions, Every market participant has the opportunity to view all the frames in the market place order orders without checking his own order against the market fen. However, the user can also use each individual order as a blanket order Mark the current order and then check against the market. As soon as a sol individual order is matched, the blanket order is automatically entered in the pri vaten area withdrawn.

Automatic matching is described below using an exemplary embodiment a market review order with orders for bundled orders changes, as it is from the vending machine taking into account the of the respective depending on the market competitor-market provider pairing dependent transfer costs to be led.

A bundle of individual orders is placed under a bundled order understood different product classes that combined into one order are summarized and accordingly delivered by the supplier in one delivery.

In the following example, transfer costs include transportation costs and the handling costs.

The transport costs are the sum of all costs to transport the product quantity specified by the market applicant in a single order from the market provider to the market applicant. It is assumed that the transport costs P _{T are} only a function of the weight and volume of the order: P _T = f (kg, m ³ ). However, other dependencies are also conceivable here, such as a dependency on the distance, the time of delivery or the countries crossed during transport.

In the following example it is assumed that the transport costs are only from Ge weight and distance.

From the buyer's point of view, the handling costs are the sum of all costs for for example the handling of the goods in the incoming goods department, the internal processing processing the supplier's invoice and all costs of the money transfer to the Supplier's account.

From the seller's point of view, the handling costs are set, for example, how follows together: handling of the goods in the warehouse, packaging ready for dispatch, hand ling in the goods issue and the internal processing of the invoice for the customer the.

The handling costs on the part of the seller and the buyer are always the same for each unbundled order and are reduced according to a function with the number of orders in a bundle P _HK = f (number of bundled orders).

According to the following example, the vending machine uses a screw stock exchange used.

A screw dealer A in Germany urgently needs the following screws and, as a market applicant, specifies the following market test parameters during its market test:

The handling costs per delivery from one supplier amount to 1 DM. This information is in the vending machine in the user database on one Storage medium saved, but can if necessary in the market review para meters to be adjusted. The one specified in the market test parameters Value overwrites the value specified in the user database if both are different.

The transfer cost module determines the weights of the from the product database Product classes for the following who are included in the market test parameters ten:

At the time of the market inspection by the screw dealer A are in Han the following orders exist:

The dealer B from the country W has an order to follow as a market provider the order parameters sent to the vending machine. Since the dealer B the dealership has written its order in the local currency mat the currency with the help of the currency module, which is via a data communication cation management receives the current exchange rate, all prices automatically the currency of trader A.

The handling costs of dealer B are according to the order parameters 1 DM per delivery from a supplier.  

First, the vending machine compares the product-specific parameters of the Order of the B and the market test order of the A. Since no differences in these parameters, the vending machine next compares the offered quantities.

In the case of individual orders, there is a deviation from the retailer's quantities A and the dealer B. Therefore, the vending machine then tests whether these deviations within those in the two complementary offers specified coverage areas. For example, dealer B is on given to deliver only if at least 30% of the quantity is accepted Dealer A has indicated to only accept an offer if at least 40% of the quantity can be supplied by one supplier. In the present For example, the two complementary offers are in the respective Überde area, so that the vending machine next the transfer costs calculates.

If the quantities offered for individual individual orders are not in the respective excess area and has determined the market competitor, only case offers one individual market vendor, the vending machine would be available in the do not end with the offer of A when creating the matching proposal take into account.

In order to generate the matching proposal, the vending machine first determines the transport costs that are incurred for the market provider-market applicant pairing of the A and the B. The vending machine reads transfer cost information on the location of A in country V and the location of B in country W from the transfer cost database and calculates the transport costs. As a result of this calculation, the transportation costs depend on the weight of the delivery:

With this information, the transfer cost module calculates the price free of charge for the delivery of the bundle order from dealer B to dealer A by adding the prices in an adding unit as follows:

Since the prices are below the price specified by dealer A, the Vending machine with the order of dealer B in the matching proposal.

Trader C, based in country X, has placed the following orders on screws in the system:

Dealer C's offer becomes the vending machine without consideration the transportation costs are not included in the matching proposal because of the envelopes order of the A and the cover order of the C different product-specific Show parameters: The case application of the C does not include any screws Product class DIN 931. The same result would be achieved if in one Individual order of a different length or a different diameter or a late delivery date would be given.

The order from dealer D in country Y is saved in the vending machine with the following parameters:

The handling costs for dealer D are 1 DM in the order parameters hold.

First, as described above, the vending machine compares the product specific parameters as well as the order quantities and their respective excess coverage areas. In the following case it is assumed that D is no excess level of coverage. With this information, the commercial car takes into account mat only the degree of coverage of the A. Since the quantities offered by D are internal The order fulfills half the coverage ratio of the individual orders of the A des D the quantity criterion of the D.

The vending machine then, as described above, first calculates the transfer costs for the mart provider-market applicant pairing of the A with the D using the transfer cost database. The result is the following assignment in the memory of the vending machine:

Taking into account the quantities in the market inquiry, the vending machine calculates the following prices:

When comparing the total prices, the comparator finds a deviation in individual order 3 in the vending machine. If this deviation lies outside a range determined in the market test parameters, the offer of A is included in the matching proposal. If this deviation exceeds a maximum price set by A, the vending machine ignores the offer of D.

In the example above, an envelope order from the vending machine was only in the matching suggestion added when all individual orders in their product-specific parameters matched. However, the trade can automat can also be set up in such a way that he receives an order from a market supplier ters first cut into his individual orders and the individual orders together other compares. The individual orders with matching product parameters, which is also within the coverage specified by the market competitor range of the order-specific parameters are then in a residual envelope packaged by the market provider. Via a linear or nonlinear optimization the vending machine can process the remaining envelopes after their agreement with the entirety of those in the market test order weight certain individual orders and in the weighting order in the mat Ching suggestion.

Finally, the vending machine can also be set so that the night question of an individual order from the market applicant from several individual orders satisfied by market providers. The composition of individual orders as Answer to a single order can also be linear or not linear optimization take place in commercial machines. You can in the Opti multiple orders from the same market provider Market candidate pairing are weighted and compared against each other.  

For this purpose, the vending machine can be connected to the comparator downstream Evaluation unit, which is the result of the parameter comparison evaluates using a cost function.

In this case, the individual orders of the C would be about the 8 mm and the 12 mm long screws with the corresponding individual orders of A over these Compare screws in the manner already described above.

Finally, it should be noted that the vending machine is also automatic Individual offers originally specified independently of each other if available can combine a market inspection order into an envelope order.
