Optimization of operation scheme for express freight railway

With the rapid development of economy, the industrial structure was adjusted constantly and the transportation demands of high value-added goods increased. The transportation demands were increased in the fast, punctual, convenient and safe way. However, China’s rapid rail freight transport had many problems, such as late start and low market share. In this paper, a multi-objective model was constructed with the maximum benefit of railway and the maximum satisfaction of freight transport demand as the target. At the same time, the method of transforming multi-objective model into single-objective model was proposed. At last, this paper took four logistics node cities in southwest China as examples to analyze the optimization method of operation plan.
