建设项目在政治、环境、经济、施工、安全等方面的风险评估的群决策过程中,各利益相关群体对于候选方案的每个属性都可以提出自己的个体决策信息,采用乘性加权集结算子构造群体决策矩阵,并判断群体决策矩阵与个体决策矩阵之间的相似度差异值,指导个体决策矩阵的修正,完成个体意见的一致化,得到最终确定评价方案的风险顺序.实例分析的结果表明,采用计算方法有利于提高多利益主体对建设项目风险评价的群决策过程中的综合满意度.
During the process of group decision-making of construction projects in the risk assessment of politics, environment, economy, construction and safety, each stakeholder group can propose his or her own individual decision information for each attribute of the candidate plan, and adopt the multiplicative weighted aggregation operator Construct group decision matrix and judge the difference of similarity between group decision matrix and individual decision matrix to guide the correction of individual decision matrix to complete the unification of individual opinions and get the risk order of the final evaluation program.Example analysis shows that , The calculation method is conducive to improving the comprehensive satisfaction of multistakeholder decision-making in the risk assessment of construction projects.
