摘要
设计了一种先"组合拍卖"再"议价谈判"的多物品两阶段采购机制.研究发现,不同于单物品采购,多物品采购两阶段机制中,组合拍卖阶段的获胜者应该区分为不同类别-四种获胜供应商,进一步分析了采购商对其应采取的相应价格策略.基本结论是,拍卖阶段存在最优获胜者确定方案和相应的激励相容投标策略.谈判阶段中,就采购商的议价策略而言,四种获胜供应商应被区别为"第一类供应商"和"第二类供应商",并分别给出了采购商采取谈判策略、按照拍卖价格交易,或宣布交易失败的相应条件.
The paper designs a two-stage mechanism for procurement.The mechanism first implements combinatorial auction then price bargaining.Particularly,it shows that an important difference between one-unit procurement auction and heterogeneous procurement auction is that there exist four types of winning suppliers in the combinatorial stage.The result indicates that in auction stage holds optimal WDP for the procurer.The suppliers also have incentive compatible bidding strategies.In bargaining stage the four types of the winning suppliers are divided into two groups,＂first class suppliers＂and＂second class suppliers＂.Finally,the paper gives corresponding conditions for procurer＇s price strategies,i.e.,initiating bargaining,using auction outcome and declaring trade failure.
