Research on Risk Element Transmission of Enterprise Project Evaluation Chain Based on Trapezoidal Fuzzy Number FAHP

摘要

In this study, a new modeling method based on trapezoidal fuzzy number FAHP has been proposed to solve the problem of risk element transmission in enterprise project evaluation chain. We firstly put forward enterprise project chain risk element transmission and constructs enterprise project chain risk element transmission tetrahedron model and then proposed the theory of enterprise project evaluation chain risk element transmission based on trapezoidal fuzzy number FAHP. After that, we introduced COWA operator and expect complementary judgment matrix and make an order about trapezoidal fuzzy number weight. Finally we prove the feasibility of this theory by an example.
