基于心理阈值的多属性决策问题目标调整研究

将决策者在决策指标上存在心理阈值的现状应用到多属性决策问题,提出先对决策目标调整再进行决策的方法。首先,对效益型、成本型、中间型指标构建相应的指标满意度函数和算法,针对不同类型的指标选择相应的算法,计算决策者在每个备选方案存在心理阈值属性上的满意度;其次,根据决策者满意度与心理阈值,调整决策目标组建新的决策信息表;再次,提出基于决策者满意度的属性赋权与信息集结算法模型,获得最优决策方案;最后,通过一个实际生活中的决策者购房案例,表明该方法的科学合理性。

A Study on Revisiting Multi-Attribute Decision Targets Based on Psychological Threshold

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.
