The current research on risk correlation focuses on the overall impact of the risk factor system on project such as cost and quality. While the identification and analysis of different kinds of risks in the system is insufficient to support the development of control measures, the network formed by the risk factors and their relationships can be used to express the risk factor system. According to the network characteristics, risk factors can be divided into aggregation risk, trigger risk, path risk and cycle growth risk. First, based on the indexes such as in degree, out degree and reachability matrix in the social network analysis (SNA) method, the above risks are identified. Then, according to the characteristics of each kind of risks, corresponding control measures are put forward. Finally, a real estate development project is taken as an example to show the analysis process of risk correlation network.%现有的风险关联研究主要分析风险因素系统对项目成本、质量等方面的整体影响.而对系统中不同类型风险的识别和分析不足,导致难以提出有效的风险管控措施.风险因素间交互影响关系形成关联网络.该网络可用于表达风险因素系统.根据风险因素的网络作用特点可将其分为汇聚风险、触发风险、路径风险和循环增长风险.社会网络分析(SNA)方法中的入度、出度和可达矩阵可用来识别上述风险,基于各类风险的网络作用特点提出相应的风险管控措施.最后以某房地产开发项目为例展示了风险关联网络分析的过程.
