AUCTION DEVICE, CONTROL METHOD FOR THE SAME, PROGRAM, AND NON-TRANSITORY INFORMATION RECORDING MEDIUM

摘要

Once a product in an auction has been purchased, a message relay (101) relays messages about sale and purchase of the product exchanged between a seller of the product and a bidder who is the winning bidder of the product, between a seller terminal used by the seller and a bidder terminal used by the winning bidder. A history storage (102) stores a history of the relayed messages. An information generator (103) uses the history to (1) estimate a seller's time that is required by the seller, in a period from when a not-yet purchased product is purchased until the product will be dispatched (2) estimates a bidder's time that is required by the bidder in the period from when the not-yet purchased product is purchased until the product will be dispatched and (3) calculates a sum of the seller's time and bidder's time, and employs the calculated sum as the expected period that is required from when the not-yet purchased product is purchased until the product will be dispatched.
