集群项目是一组相互关联并需要进行协调管理的项目.集群项目由于量大、点多,如标段划分不合理,导致管理困难,易出现质量问题.通过对影响集群项目质量的各类风险进行了量化分析,采用Borda序值构建了判断矩阵,运用风险矩阵计算出各方案的综合质量风险等级量化值,确定了集群项目基于质量风险的最优标段划分方案. Cluster project is a group of interconnected and need to coordinate the management of the project.Cluster project due to large amount, more points, such as the division of irrational, resulting in management difficulties, prone to quality problems.By the impact on the quality of the cluster project all kinds of risks A quantitative analysis was carried out, the judgment matrix was constructed by using Borda order value, the quantitative quality risk level of each plan was calculated by using the risk matrix, and the optimal segment division scheme based on quality risk of the cluster project was determined.
