| 摘 要： | 针对信息系统风险的信息不完全性和概念不明确性的特点,从风险控制角度构建一个递阶层次结构的风险评估指标体系.以灰色系统理论、模糊数学和从定性到定量的综合集成方法为理论基础,建立灰色模糊综合评判模型;并采用灰色模糊算法计算信息系统项目的风险等级,最后借助排序可能性矩阵对评价结果进行修正.通过算例分析可知,该模型的实验结果更客观.

| Abstract: | The riskes of informaiton system project are of high incompleteness and ambiguity,so an evaluation indicator system was constructed from the risk control point of view.On the theoretical basis of Grey System theory,Fuzzy Mathematics and Meta-Synthesis from qualitive methods to quantitive methods,a grey fuzzy comprehensive evaluation model was established.Then the gray fuzzy algorithm was utilized to compute the risk rank.At last,with the help of the sorting possibility matrix,the risk rank can be rectified.... |
