摘要
在复杂系统的评价中,为避免传统TOPSIS法由主观判断确定指标权重方法的不确定性和随意性,本文提出了一种改进的熵权法,对指标权重系数进行客观的确定。在确定权重的基础上,提出三种综合评价指标的计算方法,并对三种评估方法的特性进行比较分析。将改进TOPSIS法用于航空公司安全评估,取得较为满意的结果。
When TOPSIS method evaluated the from subjective judgement, this paper proposed complicated system, In order to avoid uncertainty and random resulted a improved entropy weight method to determine subjectively weight coefficient. This paper also proposed three kinds of evaluation method, and make a comparative analysis to the characteristics of these methods. The improved method used to evaluate the airline＇s safe and made a comparatively satisfactory result.
