Abstract

A method for controlling joint purchase reverse auction. The method first determines a contract price for a total procurement amount putting together purchase desires of a plurality of buyers according to a bid by at least one supplier. Then, it calculates a contract price of each buyer from the contract price for the total procurement amount at least according to a purchase scale of the buyer or a procurement price prior to reverse auction of the buyer.

Claims

1. A joint purchase reverse auction control method comprising:

determining a contract price for a total procurement amount putting together purchase desires of a plurality of buyers according to a bid by at least one supplier; and

calculating a contract price of each buyer from the contract price for the total procurement amount at least according to a purchase scale or a procurement price prior to reverse auction of the buyer.

2. The reverse auction control method of claim 1, wherein a price per unit quantity of the contract price of each buyer varies by the purchase scale of the buyer.

3. The reverse auction control method of claim 1, wherein the contract price of each buyer is calculated in such a way that a price per unit quantity of the contract price of each buyer is lower for a buyer with a lower procurement price prior to reverse auction.

4. The reverse auction control method of claim 1, wherein the contract price of each buyer is calculated in such a way that a price per unit quantity of the contract price of each buyer is lower for a buyer with a larger purchase scale.

5. The reverse auction control method of claim 1, wherein the contract price of each buyer is calculated in such a way that a price per unit quantity of the contract price of each buyer is lower for a buyer with a larger purchase scale and a lower procurement price prior to reverse auction.

6. The reverse auction control method of claim 1, wherein the contract price of each buyer is calculated by:

calculating a reduction amount of each buyer by dividing a difference between a starting price of reverse auction and the contract price for a total procurement amount by a rate weighted by the purchase scale of the buyer; and

determining an amount where the reduction amount of each buyer is subtracted from a procurement price of each buyer prior to revere auction to be the contract price of each buyer.

7. The reverse auction control method of claim 1, wherein the purchase desires are for a combination of different kinds of items.

8. A computer program product for causing a computer to execute control of joint purchase reverse auction, the computer program product including a computer readable medium storing a program code, the program code comprising:

a first program code determining a contract price for a total procurement amount putting together purchase desires of a plurality of buyers according to a bid by at least one supplier; and

a second program code calculating a contract price of each buyer from the contract price for the total procurement amount at least according to a purchase scale or a procurement price prior to reverse auction of the buyer.

9. A computer program product of claim 8, wherein a price per unit quantity of the contract price of each buyer calculated by the second program code varies by the purchase scale of the buyer.

10. A computer program product of claim 8, wherein the second program code calculates the contract price of each buyer in such a way that a price per unit quantity of the contract price of each buyer is lower for a buyer with a lower procurement price prior to reverse auction.

11. A computer program product of claim 8, wherein the second program code calculates the contract price of each buyer in such a way that a price per unit quantity of the contract price of each buyer is lower for a buyer with a larger purchase scale.

12. A computer program product of claim 8, wherein the second program code calculates the contract price of each buyer in such a way that a price per unit quantity of the contract price of each buyer is lower for a buyer with a larger purchase scale and a lower procurement price prior to reverse auction.

13. A computer program product of claim 8, wherein the second program code calculates a reduction amount of each buyer by dividing a difference between a starting price of reverse auction and the contract price for a total procurement amount by a rate weighted by the purchase scale of the buyer, and determines an amount where the reduction amount of each buyer is subtracted from a procurement price of each buyer prior to revere auction to be the contract price of each buyer.

14. A server for implementing control of joint purchase revere auction, comprising

a unit of determining a contract price for a total procurement amount putting together purchase desires of a plurality of buyers according to a bid by at least one supplier;

and

a unit of calculating a contract price of each buyer from the contract price for the total procurement amount at least according to a purchase scale or a procurement price prior to reverse auction of the buyer.

15. The server of claim 14, wherein a price per unit quantity of the contract price of each buyer calculated by the unit of determining a contract price varies by the purchase scale of the buyer.

16. The server of claim 14, wherein the unit of determining a contract price calculates the contract price of each buyer in such a way that a price per unit quantity of the contract price of each buyer is lower for a buyer with a lower procurement price prior to reverse auction.

17. The server of claim 14, wherein the unit of determining a contract price calculates the contract price of each buyer in such a way that a price per unit quantity of the contract price of each buyer is lower for a buyer with a larger purchase scale.

18. The server of claim 14, wherein the unit of determining a contract price calculates the contract price of each buyer in such a way that a price per unit quantity of the contract price of each buyer is lower for a buyer with a larger purchase scale and a lower procurement price prior to reverse auction.

19. The server of claim 14, wherein the unit of determining a contract price calculates a reduction amount of each buyer by dividing a difference between a starting price of reverse auction and the contract price for a total procurement amount by a rate weighted by the purchase scale of the buyer, and determines an amount where the reduction amount of each buyer is subtracted from a procurement price of each buyer prior to revere auction to be the contract price of each buyer.
