Gray Correlation Comprehensive Evaluation of Port Intermodal Transport Development Level Based on Expert Group Decision-Making Weight Optimization

Abstract

This paper adopts the weight optimization method based on expert group decisionmaking technology to optimize the weights of the influencing factors affecting the development level of port intermodal transport, and then adopts the gray correlation comprehensive evaluation method to evaluate the development level of port intermodal transport in China from three aspects of supply capacity, service level and development environment. The results prove that the evaluation method is practical and effective, and can provide support for the evaluation of the development level of port intermodal transport in China.
