Research of Fuzzy Entropy Weight Model on the Risk Evaluating of Wuhan Yangtze River Highway Tunnel

摘要

The quantitative description on risk analysis is the assumption of risk management. Traditional risk assessment methods of engineering project are often affected by subjective factors. Fuzzy comprehensive evaluation by entropy weight model serve as a tool provide us a way to assess the risk. This new method could reduce or avoid the effect of subjective factors and fuzzy factors. This article introduce the basic theory of the method and analyze the risk of Wuhan Yangtze River Highway Tunnel ,then calculates various risks factor using the entropy power the weight, and combines fuzzy mathematics method to establish evaluation model by combining qualitative analysis and quantificational computability, to evaluate the risk factor and to draw the conclusion. The practical analysis has proven that this method is preferable and feasible.
