Abstract: We determine the index system for efficiency evaluation of empty wagon allocation by analyzing the influential factors of empty wagon allocation in railway networks.We also acquire the evaluation grade of an optimal target in the empty wagon allocation issue by the idea oftripartite game.We further construct anempty wagon allocation efficiency model in railway networks with fuzzy comprehensive evaluation method. The model is verified with the railway network in Lanzhou railway administration as an example. It has important practical significance for improving the quality of railway freight transportation.

Key words: efficiency, game;indexsystem, fuzzy comprehensive evaluation, empty wagon allocation
