Abstract

Abstract: In view of the subjective arbitrariness of objective weight in multi-objective decision making based on Vague sets and the monotong problem of evaluation function, a novel approach to multi-objective decision making based on entropy weighted-Vague sets was presented. Firstly, the decision matrix was transformed into the objective-grade-membership matrix. Then the objective weight of each objective was calculated by entropy coefficient method, and the weight vector interval of each objective was obtained by considering objective weight and subjective weight. Next the Vague evaluation was obtained by computing the sets of objectives being in favor, against and neutral. Finally, a new evaluation function was defined to sort the alternatives and select the optimal scheme. The rationality and effectiveness of the method were verified by an example.

摘要： 针对目前基于Vague集的多目标决策中目标权重的主观任意性以及评价函数的单一性问题，提出一种基于熵权Vague集的多目标决策方法。首先，将决策矩阵转化为目标优属度矩阵，再利用熵权系数法计算各个目标的客观权重，综合考虑客观权重和主观权重得到各个目标的权重向量区间；然后，通过计算方案的支持目标集、反对目标集和中立目标集得出方案的Vague估计值；最后，定义新的评价函数对方案进行排序并选出最优方案。通过算例验证了所提方法的合理性和有效性。
