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。
Determining the traffic flow path is an important part of railway traffic organization. The merits of its choice directly affect the transport efficiency and economic benefits of the regional railway network. In this paper, a multi-objective optimization method based on the principle of satisfaction is proposed. In order to solve the difficulty and shortcomings of the objective optimization in solving general traffic flow routing problems, the multi-objective optimization method for traffic flow in two-way, The goal satisfaction optimization model, and through the establishment of independent satisfaction and comprehensive satisfaction to measure the quality of optimal solution. The case study shows that the satisfactory optimization method is more suitable and effective than the traditional optimization theory for the actual traffic flow routing problem.
