Abstract

The server registers a plurality of supplier groups composed of one supplier or a combination of two or more suppliers so as to offer all items constituting a procurement object in a supplier group list. Then, it receives a bid price of a first supplier for an item included in the procurement object from a supplier terminal. Further, it selects the supplier group to which the first supplier belongs to with reference to the supplier group list and calculates a group bid price by summing up the bid prices of the suppliers belonging to the selected supplier group. Finally, it compares the calculated group bid price with the group bid prices of other supplier groups and determines a supplier group to be a candidate for the procurement object.

Claims

1. A control method of reverse auction executed by a server connected to a buyer terminal and a plurality of supplier terminals through a communication network, the method comprising:

registering, in a group memory unit, a plurality of supplier groups composed of one supplier or a combination of two or more suppliers so as to offer all items constituting a procurement object;

receiving a bid price of a first supplier for an item included in the procurement object from one of the supplier terminals;

calculating a group bid price by adding the bid price of the first supplier and a bid price of another supplier included in a supplier group where the first supplier belongs with reference to the group memory unit; and

determining a supplier group to be a candidate for the procurement object by comparing the calculated group bid price with a group bid price of another supplier group.

2. The control method of reverse auction according to claim 1, wherein the registering step comprises:

receiving information of an item that the supplier desires to bid for and that is included in the procurement object from the supplier terminal;

creating a plurality of supplier groups composed of one supplier or a combination of two or more suppliers so as to offer all items constituting the procurement object based on the information of the item that the supplier desires to bid for; and

registering the plurality of supplier groups in the group memory unit.

3. The control method of reverse auction according to claim 1, wherein the determining step ranks supplier groups in ascending order of the group bid price and determines a supplier group with a lowest group bid price to be a successful supplier group for the procurement object.

4. The control method of reverse auction according to claim 3, further comprising:

notifying a rank of each supplier group determined in the determining step to each supplier terminal used by a supplier that belongs to each supplier group.

5. The control method of reverse auction according to claim 1, wherein at least one supplier belongs to two or more supplier groups contained in the plurality of supplier groups which are generated in the registering step.

6. The control method of reverse auction according to claim 1, wherein the registering step comprises:

transmitting a approval request to approve the plurality of supplier groups to the buyer terminal;

receiving a approval information for the approval request from the buyer terminal; and

eliminating a supplier group denied by the buyer from the group memory unit based on the approval information.

7. The control method of reverse auction according to claim 6, wherein the determining step further comprises:

determining the supplier group to be a candidate for the procurement object by comparing the calculated group bid price with a group bid price of the supplier group denied by the buyer.

8. A computer program product for causing a computer connected to a buyer terminal and a plurality of supplier terminals through a communication network to execute a control process of reverse auction, the control process comprising:

registering, in a group memory unit, a plurality of supplier groups composed of one supplier or a combination of two or more suppliers so as to offer all items constituting a procurement object;

receiving a bid price of a first supplier for an item included in the procurement object from one of the supplier terminals;

calculating a group bid price by adding the bid price of the first supplier and a bid price of another supplier included in a supplier group where the first supplier belongs with reference to the group memory unit; and

determining a supplier group to be a candidate for the procurement object by comparing the calculated group bid price with a group bid price of another supplier group.

9. The computer program product according to claim 8, wherein the registering step comprises:

receiving information of an item that the supplier desires to bid for and that is included in the procurement object from the supplier terminal;

creating a plurality of supplier groups composed of one supplier or a combination of two or more suppliers so as to offer all items constituting the procurement object based on the information of the item that the supplier desires to bid for; and

registering the plurality of supplier groups in the group memory unit.

10. The computer program product according to claim 8, wherein the determining step ranks supplier groups in ascending order of the group bid price and determines a supplier group with a lowest group bid price to be a successful supplier group for the procurement object.

11. The computer program product according to claim 10, wherein the control process further comprises:

notifying a rank of each supplier group determined in the determining step to each supplier terminal used by a supplier that belongs to each supplier group.

12. The computer program product according to claim 8, wherein at least one supplier belongs to two or more supplier groups which are generated in the registering step.

13. A server connectable to a buyer terminal and a plurality of supplier terminals through a communication network and implementing control of reverse auction, the server comprising:

a registration unit registering, in a group memory unit, a plurality of supplier groups composed of one supplier or a combination of two or more suppliers so as to offer all items constituting a procurement object;

a receiving unit receiving a bid price of a first supplier for an item included in the procurement object from one of the supplier terminals;

a calculation unit calculating a group bid price by adding the bid price of the first supplier and a bid price of another supplier included in a supplier group where the first supplier belongs with reference to the group memory unit; and

a determination unit determining a supplier group to be a candidate for the procurement object by comparing the calculated group bid price with a group bid price of another supplier group.

14. The server according to claim 13, wherein the registration unit receives information of an item that the supplier desires to bid for and that is included in the procurement object from the supplier terminal, creates a plurality of supplier groups composed of one supplier or a combination of two or more suppliers so as to offer all items constituting the procurement object based on the information of the item that the supplier desires to bid for, and registers the plurality of supplier groups in the group memory unit.

15. The server according to claim 13, wherein the determination unit ranks supplier groups in ascending order of the group bid price and determines a supplier group with a lowest group bid price to be a successful supplier group for the procurement object.

16. The server according to claim 15, further comprising:

a notification unit notifying a rank of each supplier group determined in the determining step to each supplier terminal used by a supplier that belongs to each supplier group.

17. The server according to claim 13, wherein at least one supplier belongs to two or more supplier groups which are generated by the registration unit.
