摘要
属性权重研究是IT项目风险分析的重要过程,在分析属性权重、研究同类方法的基础上,指出了通过传统方法以及粗集方法确定单个属性权重存在的一些问题,由此提出了基于粗集理论的属性组合权重的概念与计算方法,最后根据组合权重的相似系数矩阵,对风险因素进行聚类分析,为项目管理提供决策依据。
The weight of factors is an important process in IT project risk analysis. After discussing the relative methods of factor weight evaluation, some problem in the traditional ways were pointed out, the concept of the combination weight was put forward, and a way to assess its weight based on rough set was given. According to the combination weight and the matrix of similarity coefficient, the risk factors in IT projects were classified by cluster analysis to make the correct decision for project management.
