<p>PROBLEM TO BE SOLVED: To solve a problem wherein there is a case where a bidder must have a membership and pay a membership fee to operate an auction exhibiting commodities of a company, but the bidder is not guaranteed that he/she can make a successful bid for his/her desired commodity in this case and thereby the number of members cannot be easily increased. SOLUTION: Also a non-member is allowed to perform a bidding and is made to pay the membership fee when he/she made the successful bid for a commodity. When a successful bid for a general commodity with a high successful bid probability is made, a bidding entry number for auctioning a special commodity with a low successful bid probability is increased.</p> |
