Study of the Decision-Making Based on Two Targets in Bidding

On condition that the numbers of participators are uncertain,this paper,based on introducing a proportion coefficientα,constructs a decision-making model of two targets,which improves the single decision- making model based on expected profits in Friedman model and Hassman-Rivett model.In the two models above, winning probability and expected profits vary inversely which cause the difficulty of decision-making.The model we construct effectively resolves the defect above.
