A technological means that collects order applications from a larger number of buyers in a group-purchasing reverse auction. During an auction session T-k, a control unit 310 in a reverse auction support device 30 performs the following processes in parallel: displaying a latest bid price in response to a request from a buyer terminal 10-m; adding an order entry information item OD received from a buyer terminal 10-m, to an order management database ODB-k; displaying a latest total order count and latest bid price in response to a request from a supplier terminal 20-n; and appending a bid information item RD received from a supplier terminal 20-n, to a bid management database RDB-k. After the auction session T-k has ended, the control unit 310 selects a bid information item RD1ST that has the highest bid rank, from among all the bid information items RD in the bid management database RDB-k. |
