Abstract: Decision maker's utility or value may not depend on the levels of performance on different criteria, but instead on whether the levels meet a target or threshold on one or more criteria. In this paper, based on this psychological threshold, a new decision analysis method is proposed. First, three criteria satisfaction functions are constructed corresponding to three different types of criteria, respectively. Second, the decision targets according to the satisfaction degrees of the decision makers are revised. Using the selected alternatives and criteria, a new decision table is constructed. Third, a new method is proposed to obtain the criteria and aggregate the information based on the satisfaction degree of the decision makers. Finally, an example is used to demonstrate that the method is scientific and effective as well as feasible.

Key words: decision analysis, psychological threshold, satisfaction degree, revisiting decision targets, obtaining criteria weights, information aggregation
