【摘要】 多属性采购拍卖在企业采购中具有重要意义。在已知买方效用函数的前提下,传统多属性采购拍卖主要从买家角度出发,致力于拍卖机制和赢者决定问题,而供应商的决策模型少有研究。在采购商的效用函数未知的前提下,基于DEA理论,利用以往赢家的信息建立了供应商投标的数学模型,并通过数值例子阐述了模型了应用价值。所得结果既有助于供应商正确推断卖方属性偏好权重值,确定投标策略,增加胜标机会,又有助于提高供应商的能力,促进供应商之间的竞争,增加采购商的效用。更多还原

【Abstract】 Multi-attribute procurement auction is gaining significant importance in industrial procurement.In a traditional model,a great deal of efforts is addressed issues relating to auction mechanism design and winner determination problem under the known utility function of auctioneer.There is little research on the bidding strategies model of supplier.Based on the DEA theory,the prior winners’ information was used and the bidding strategies model of supplier was proposed with the unknown utility function of procurer.The numerical example expounded application of the model.The results both help suppliers correctly infer the seller’s attribute weights and determined bidding strategy.It also can help procurer increase competition between suppliers and improve buyer’s utility.更多还原
