摘要
对于信息系统方案评价这种复杂问题提出一种新的方法 ,以避免主观判断的不确定性和随意性。针对传统信息系统项目评标中单纯由主观判断确定指标权重方法的不足 ,提出了将主观判断与客观情况相结合、定性定量相结合的熵权法来确定指标的权重系数 ,进而将 TOPSIS法与熵权系数综合集成进行合理方案的评价。将该方法应用于评标过程的实践 ,取得了较为满意的结果。
A new approach to the complex problem of the rationality in evaluating information system integration is proposed to avoid non-determinacy and optional judgement resulted from subjective opinions. To ameliorate the inefficiency of means to decide proportion coefficient in the course of the evaluation of information system integration, subjective opinions are combined with objective situations and the quantitative analyses are combined with qualitative analyses. The weight coefficient is given by means of entropy coefficient and TOPSIS method for the first time. The proposed method is applied to evaluating information system integration solutions and satisfactory results are obtained.
