风险定量评估等风险图算法修正

Modification of Equal Risk Graph Algorithm for Quantitative Risk Assessment

等风险图法以其简便直观的办法可以快速对项目的风险做出定量评估,但由于其未考虑各风险概率与风险后果的权重,不能较为准确量化风险值,本文在等风险图法的基础上使用层次分析法对风险和后果引入权重因子,使风险量化更为准确。

The equal risk graph method can quickly make quantitative evaluation of the project risk with its simple and intuitive method,but it can not accurately quantify the risk value because it does not consider the weight of each risk probability and risk consequence.In this paper,the AHP method is used to introduce the weight factors into the risk and consequence in the risk evaluation,so as to make the risk quantification more accurate.
