【摘要】 拍卖机制与竞标人出价策略是拍卖理论研究的核心问题,网上拍卖的时间终止规则有固定时间和固定期限无应答两种类型.网上拍卖最后时刻投标对竞标人往往是最优策略,但是会影响到拍卖的效率.有时间约束的多属性网上顺序拍卖,通过设定最后一轮的拍卖机制,在最后一轮拍卖中,新的竞标人不准许加入拍卖,每一个竞标人按顺序只能提交一次报价,在投标结束后拍卖人根据评分函数和最优权重对竞标评分.这种拍卖机制有利于提高拍卖人收益,同时又给竞标人提供一种稳定的策略,可以有效地避免最后时刻投标所带来的效率损失.更多还原

【Abstract】 Auction mechanism and bidding strategy are the core issues of auction theory.The rules of online auction for termination include two types: a fixed time and fixed-time with non-response.The last minute bidding for bidders is the optimal strategy,but it will affect the efficiency of online auction.To overcome the problem,a new scheme for multi-attribute sequential auction based on time constraints is presented.The scheme is defined as follows: new bidders are not allowed to join the auction in the final round;each bidder can submit their bidding price for only once;auctioneer grades to competitive bidding according to score function and optimum weights.Compared with previous work,this auction mechanism can raise income of auctioneer,provide a stable strategy for bidder,and improve efficiency effectively.更多还原
