基于粗集的代建制项目风险因素模糊聚类研究

代建制自从在我国政府投资项目中应用以来,取得了明显成效,但是代建制风险研究相对滞后。根据代建制项目的特点,总结代建制项目风险因素和相应后果;在风险分析中属性权重的确定是一个重要过程,指出只考虑单一风险因素对项目影响的局限性,指出风险分析中应考虑风险因素之间的相互作用和风险因素组合对项目的影响,利用粗集原理对代建制项目的风险因素组合权重进行计算,最后应用传递闭包法对风险因素组合进行模糊聚类分析,为代建制项目风险管理提供了一种简便和较为客观的分析方法。

Fuzzy Cluster Analysis of Agency Construction Project Based on Rough Set

Since the application of agency construction in government investment projects,the obvious effects have been achieved,but the risk research is hysteresis.This paper points out the limitation of the traditional ways,put forwards the concept of combination weight and rough set to calculate the risk combination weights.According to the combination weights and the matrix of similarity coefficient,it classifies the risk factors based on fuzzy cluster analysis method.
