The Research on Development Risk of Green Construction Material Based on Fuzzy Comprehensive Evaluation

In order to analyze and select the development project of green construction material more scientific and rational, the fuzzy comprehensive evaluation method in fuzzy set theory is introduced in this paper to evaluate development risk and establish comprehensive evaluation model for development risk of green construction material. This paper adopts risk priority number (RPN) which from failure mode effects and criticality analysis (FEMCA), to analyze the risk scale, set risk weight, and let this setting closer to actual condition, then calculating examples. At last we conclude that the method provides feasible analysis foundation, and has the strong practical value.
