Abstract: With the development of railway transport enterprises, the quality of railway freight service has gradually become the key to improve the competitiveness of transport enterprises and win the market. This paper determined the weight of the index based on the analytic hierarchy process (AHP), and used the fuzzy comprehensive evaluation method to evaluate the freight service quality, which improved the accuracy of the traditional fuzzy comprehensive evaluation results. Taking Nanchang North Freight Station as a representative monitoring station, the railway freight service quality index system was established to monitor and obtain relevant data. According to the analysis results, the paper pointed out existing problems of railway freight service quality, and put forward suggestions for improvement, so as to improve the overall level of railway freight environment and provide customers with better service.
