摘要/Abstract

摘要：

在多目标决策中，通常都涉及到指标权重的计算问题．针对现有权重计算方法中存在的不足，提出了一种改进的熵权层次分析法．该方法将熵权法和层次分析法的中间过程相结合，将熵权法的底层指标客观权重与层次分析法的子准则主观权重对应结合后，再与上层指标权重综合，归一化后得到最终的指标权重．结果表明，求得的权重具有更高的可信度．

关键词: 多目标决策, 层次分析法, 熵权法

Abstract:

In multi-objective decision, the problem of computing the weights of the indexes is usually considered In view of the shortcomings in the existing techniques, this paper proposes an improved weights determination method by the efficient combination of the entropy weight method (EWM) and the analytic hierarchy process (AHP). In the presented method, the amalgamation is firstly carried out between the objective weights of underlying indexes by EWM and the subjective weights of indexes on the sub-criterion level by AHP. The obtained weights of indexes are synthesized subsequently with the weights of upper indexes. After normalization, the final weights of indexes are obtained. The results show that the final weights by this presented method have higher reliability.

Key words: multi-objective decision, analytic hierarchy process, entropy weight method
