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。
Applying the present situation that the decision maker has the psychological threshold in the decision index to the multi-attribute decision-making problem, this paper puts forward the method that the policy-making goal is adjusted and then the decision is made first. First of all, corresponding index satisfaction functions and algorithms are constructed for benefit, cost and intermediate indexes. Corresponding algorithms are selected for different types of indicators to calculate the satisfaction degree of decision makers on the existence of psychological threshold attributes of each alternative. Secondly, we set up a new decision-making information table according to the decision-maker’s satisfaction and the psychological threshold. Thirdly, we propose a model of attribute empowerment and information aggregation based on the satisfaction of decision-makers to get the optimal decision-making plan. Finally, Life decision-makers purchase cases, indicating that the method of scientific rationality.
