基于非对称投标人的反向多属性英式拍卖模型与最优投标策略

针对现有的模型均以投标人是对称的这一刚性假设的局限性, 建立了基于非对称投标人的反向多属性英式拍卖模型, 并在新的拍卖模型中加入投标质量属性最低值约束, 弥补了现有模型在没有考虑实际反向拍卖中拍卖人一般对投标质量属性值会有最低限制这一客观需求的缺陷. 最后基于新的拍卖模型, 给出了结构化的最优投标策略和拍卖过程描述及示例. 上述研究结果适用于通过反向多属性拍卖与信息技术相结合的网上自动化采购和投标人决策支持.

Reverse multi-attribute English auction model and optimal bidding strategies based on asymmetric bidders

The existing models all have a rigid assumption that the bidders are symmetrical.To improve the limitation of these models,reverse multi-attribute English auction model based on the asymmetric bidders is established.The new auction model includes the constraints of the minimum value of bidding quality attributes.The improvement of the model makes up the defect that existing models do not consider the auctioneer’s usually objective demand of the minimum value of bidding quality attributes in the reality.Finally,based on the new auction model,the author gives the structurized optimal bidding strategies and describes the process of auction and one example.The research results apply to online automatic procurement and bidders’ decision support through the combination of reverse multi-attribute auction and information technology.
