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.
