摘　　要：多属性反向拍卖作为一种电子采购方式已被广泛应用于电子商务中。在大多数拍卖模型中,投标者的标价信息对于拍卖者来说完全公开,在拍卖者和个别投标者共谋情况下,会造成投标者之间的地位不平等,给其他投标者造成经济损失。文中在逼近理想解评标方法和安全多方计算基础上,提出一种保护标价的多属性反向拍卖模型,该模型采用了安全逼近理想解协议,实现标价保密和投标者地位公平,抵御拍卖者与个别投标者的共谋。Reverse auction is widely used in electronic-commerce as an electronic-procurement method. However in the most auction models,the bid information of bidders is completely open to the auctioneer. It will result in inequalities between bidders and cause their losses in the case of complicity between the auctioneer and some bidders. Based on technique for order preference by similarity to ideal solution and secure multi-party computation,the bid price protected multi-attribute reverse auction model is presented. It makes use of a secure technique for order preference by similarity to ideal solution. This model realizes the security of bid-prices and the fairness of bidders, and withstands the complicity between auctioneer and bidder.
