基于前景理论和模糊理论的在线多属性采购拍卖供应商选择决策

Decision method of supplier selection for online multi-attribute procurement auction based on prospect theory and fuzzy theory

在线多属性采购拍卖已在工程招标、政府采购等诸多领域有着广泛应用.由于在实际的采购拍卖活动中,往往采购方对采购商品的相关属性指标存在不同程度的不确定性,采购商在对采购品属性的描述及相应权重的确定上都存在困难,进而导致采购商在面临供应商选择决策上难度增大.为了解决这些问题,从采购方利益角度出发,考虑风险态度对决策者行为的影响,引入前景理论,研究4种模糊描述方式并存情况下的在线多属性采购拍卖的供应商选择决策问题;在综合考虑主客观因素确定属性权重的情况下,提出一种新的在线多属性采购拍卖供应商选择决策方法;最后通过相关的算例分析与比较说明所提出方法的有效性.

Online multi-attribute procurement auction has been widely used in many fields,such as project bidding,government procurement and so on.However,in the actual procurement auction,purchasers often have varying degrees of uncertainty about the information such as commodity related attributes.So it is difficult to describe related attributes and determine the corresponding weights,thereby increasing the difficulty of purchaser’s decision on supplier selection.To deal with these problems,from the purchaser’s interests,considering the influence of the risk attitude on decision-making behavior and introduce the prospect theory,we study the decision question of supplier selection for online multi-attribute procurement auction in the case of coexistence of four fuzzy description modes.Under the condition of comprehensive considering of the subjective and objective factors for determining the attribute weights,we propose a new decision method of supplier selection for online multi-attribute procurement auction.Finally,relevant example analysis and comparison illustrate the effectiveness of the proposed method.
