Evaluation of financing scheme of railway construction project based on improved fuzzy AHP

China's railway development coincides with the comprehensive deepening reform. In order to promote the smooth completion of construction projects by adopting the best financing scheme, aiming at the technical problems that the financing scheme of railway construction projects is difficult to determine, on the basis of constructing the evaluation index system of project financing scheme, and based on the improved analytic hierarchy process and fuzzy comprehensive evaluation method, the evaluation index weights are determined from the angles of financing structure, financing cost, financing risk, profitability and viability. Then, the comprehensive evaluation of the financing scheme of railway construction project is carried out, and the effectiveness of the proposed method is verified by taking the Shanghai-Jiaxing-Ningbo railway project as an example. Combined with the evaluation results, relevant suggestions that are beneficial to the smooth implementation of the project are put forward. The results show that the proposed method can effectively evaluate the financing scheme of railway construction projects, and the corresponding research results can provide reference for the investment and financing of railway construction projects.
