考虑决策者心理行为的直觉语言多属性决策方法

Multiple Attribute Decision-making Method of Intuitionistic Linguistic Considering Psychological Behavior of Decision-maker

针对应用直觉语言集来表达决策信息的语言多属性决策问题,在考虑决策者有限理性的心理行为基础上,提出一种决策方法。该方法通过比较每个属性下方案之间的得分函数和精确函数,构建方案的收益-损失分析矩阵。在考虑决策者参照依赖和损失规避心理行为基础上,计算每个方案相对于其它方案在每个属性下的收益-损失值优先度;在此基础上,计算备选方案的综合优先度,并根据其大小对方案进行排序择优。最后通过一个算例验证所提出方法的有效性和合理性。

Aiming at the linguistic multi-attribute decision making problem in which intuitive linguistic sets are used to express decision information, a decision-making method is proposed on the basis of considering the decision maker’s bounded rational psychological behavior. The method constructs the benefit-loss analysis matrix of the scheme by comparing the score function and the exact function between the schemes under each attribute. Considering the decision-maker’s psychological behavior of dependence and loss avoidance, the priority of benefit-loss value of each alternative is calculated relative to that of other alternatives under each attribute. On this basis, the comprehensive priority of alternatives is calculated, and the alternatives are ranked according to their size. Finally, an example is given to verify the validity and rationality of the proposed method.
