浅析基于多属性决策理论的评估系统中的熵权法

Entropy Method in Evaluation System Based on Multiple Attributive Decision Theory

面向多属性多指标评估系统,在测评者对各指标及受测者都很熟悉的情况下,探索一种适合的赋权方法。主要阐述了熵权法的原理及计算过程,并结合实例进行应用分析,结果表明,熵权法比其他方法能更好地解决该情况下的指标赋权问题。由此得出结论:熵权法是非专业性评估系统中各指标的最佳赋权方法。

This paper attempts to find a suitable weighting method for the evaluatien system with multi-characters and multi-indexes on the condition that the evaluator is familiar with each index and subject of the evaluation system. The principle and calculation process of the entropy method is explained with analysis made in accordance with actual examples. Analysis shows that the en- tropy weight method can better solve the index weighting problem than other ones.It is conclu- ded that entropy is the best method for index weighting in non-professional evaluation system.
