Assessment of Grid Construction Project Risk of Process Based on Fuzzy-Event Tree-Fault Tree

Power grid construction projects play an important role in the development of economic as the infrastructure facility. But there is a lot of risk in the process of power grid construction projects. This paper evaluates the risk by the method of fuzzy-incident tree-fault tree. Fuzzy-event tree -fault tree is an integrated and qualitative analysis method that based on fuzzy math and fuzzy set theory. According to this analysis, we can avoid risk and achieve the goal for construction of the power grid project.
