A Dynamic Grey Fuzzy Evaluation Method for Financing Risk in Freeway Project

There are many risks that influence freeway project financing and the influence of these risks differ by project stage. However, it is impossible to analyze the total risk of project financing objectively and accurately merely using the fuzzy or grey evaluation methods. These methods cannot reflect the dynamic characteristics of financing risks during freeway project construction. A dynamically grey fuzzy comprehensive evaluation method was established and used to evaluate the financing risks of a freeway project. The results indicate that this method can not only make full use of the rich experience of the experts, but also reduce the influence of subjective factors. In addition, this method can reflect the dynamic characteristics of the financing risks during freeway project construction. Investors therefore can pertinently prevent and control financing risks based on the results of the evaluation of financing risks in every stage of the project. A demonstration shows that the method is suitable for comprehensive evaluation of financing risks of infrastructure projects such as freeways.
