路网车流径路的满意优化

确定车流径路是铁路行车组织中的一项重要内容，其选择的优劣直接影响了区域铁路网的运输效率和经济效益。本文应用基于满意度原理的多目标优化方法，针对一般车流径路问题求解中追求目标最优的难度和不足，改进了在一定运输需求条件下对路网上双向、空重车流径路同时进行优化的多目标满意优化模型，并通过建立独立满意度和综合满意度来衡量优化解的品质。实例分析表明，对于实际的车流径路问题，满意优化方法比传统的最优化理论方法更适用和更有效。

Satisfactory Optimization of the Wagon Flow Problem in Railway Network

Problem of the wagon flow path is important in the organizing of the railway transport. The scheme of wagon flow path directly affects the efficiency and benefit of transportation of railway network. Against at the difficulty and fault of the general multi-objective optimization of the wagon flow problem, based on the multi-objective satisfactory optimization theory, the paper improves the multi-optimization model of the bidirectional, empty-loaded car wagon flow problem for the certain transportation demand. Then, the paper establishes the independence satisfactory degree and comprehensive satis factory degree for the solution to appraise the optimization result. The application shows that the satisfactory optimization is more applicable and effective than the general theoretical optimization for the wagon flow problem.
