Abstract

A method is described for carrying out a reverse electronic online auction between a number of bidders and one buyer for the procurement of a product needed by the buyer, over a communications network, having the following steps:

selecting a limited number of bidders based on a specified request for bid by the buyer,

notifying the bidders concerning the point in time, the duration of the auction and the online auction room of the auction,

carrying out the auction at the time period stated, each bidder being able to make his bids during the permissible time period,

each bidder has indicated to him the most favorable bid of the competitors in anonymous form and the remaining auction time, and

calculating a comparison quantity overall costs as a function of the particular price and of further suitable criteria, for comparing the bids of the individual bidders online for each bid, the auction being extended by at least one predetermined time period.

Claims

1. A method for carrying out an electronic online auction between a number of bidders and one buyer for the procurement of a product needed by the buyer over a communications network having the following steps:

selecting a number of bidders who are able to make the product available,

notifying the bidders concerning the time, the permissible time period of the auction provided and the online auction room of the auction,

carrying out the auction at the specified point in time, each bidder being able to make his bids during the permissible time period which is formed by the specified first time duration, each bidder having indicated to him at least the lowest bid of the competitors in an anonymous form and the remaining auction time, and for comparison of the bids of the individual bidders, online, for each bid, a comparison quantity overall costs is calculated as a function of the particular price and of further suitable criteria,

wherein the permissible time duration of the auction is extended before its expiration by an extension interval, so that a new permissible time duration comes about.

2. The method as recited in claim 1, wherein a remaining time interval is defined, and only this remaining time interval is notified to the bidders when the remaining auction time is less than, or equal to the remaining time interval.

3. The method as recited in claim 2, wherein the extension of the auction is carried out in the remaining time interval.

4. The method as recited in one of the preceding claims, wherein the duration of the extension interval is selectable for each extension.

5. A method, particularly as recited in one of the preceding claims, for carrying out an electronic auction having a number of bidders and one buyer for the procurement of a product needed by the buyer over a communications network having the following steps:

selecting a limited number of bidders based on a specified request for bid by the buyer,

notifying the bidders concerning the point in time, the permissible time period of the auction and the online auction room of the auction,

carrying out the auction at the specified time period, each bidder being able to make his bids during the permissible time period, each bidder having indicated to him at least the most favorable bid of the competitors in an anonymous form and the remaining auction time, and for comparison of the bids of the individual bidders, online, for each bid, a comparison variable overall costs is calculated as a function of the particular price and of further suitable criteria,

wherein each bid includes a specified number of various cost variables, each cost variable being an essential quantity for the buyer'"'"'s decision making, and the overall turnover as well as further cost functions are ascertained for each bid from the stated cost variables of a bid according to a predefined algorithm, the overall turnover for each bidder being calculated online to the exact day, using his current bid for the delivery time period provided.

6. The method as recited in claim 5, wherein besides the parameter A-price, i.e. the price at the supplier, the bid of a bidder also includes at least one B-price, i.e. the price including delivery to a specified location, the possible delivery volume, the necessary investment on the part of the buyer, i.e., for example, tooling costs, and the long term conditions for a delivery in specified consecutive time periods.

7. The method as recited in claim 5 or 6, wherein the lowest bid, which is sent to each bidder in anonymous form, is composed of the most favorable cost quantities of all the bids made.

8. The method as recited in one of claims 5-7, wherein the savings are calculated for each bidder for the delivery time period provided, using the cost variables stated, the overall turnover of the preceding delivery period being used for the calculation.

9. The method as recited in one of claims 5-8, wherein the cost functions calculated online from the cost quantities are indicated to the buyer.

10. The method according to one of the preceding claims, wherein for admission to the auction, each bidder has to satisfy a set of quality requirements which is a component of the request for bid.

11. The method according to one of the preceding claims, wherein after the end of the auction, a subset of the bidders is selected with the aid of the calculated cost functions, using which, renegotiations are held in the form of a further online auction.

12. The method according to one of the preceding claims, wherein each selected bidder obtains access to the online auction by using an individual key.

13. The method according to one of the preceding claims, wherein a reverse auction is carried out.

14. A device for carrying out the method as recited in one of the preceding claims, having a server, for carrying out the auction, bidder stations connected to the server over a communications network and a device for ascertaining online the particular cost functions of a bid.

15. The device as recited in claim 14, wherein the communications network is formed by the Internet.

16. The device as recited in one of claim 14 or 15, wherein the communications between the server and the bidder stations take place in coded form.

17. The device as recited in one of claims 14-16, wherein each bidder station has an indicator device and an input device, a bidder form for inputting a bid being shown on the indicator device, and a bidder form includes information concerning the last valid bid of the bidder, the most favorable current bid of the other bidders in anonymous form, the remaining duration of the auction and the subject matter of the auction, and input fields for inputting a new bid are provided.

18. A computer program having program code means for carrying out all the steps of the method according to one of claims 1-13, when the program is run on a computer.

19. The computer program having program code means according to claim 18, which are stored on a computer-readable data carrier.
