铁路超限货车挂运方案优化模型 - 图文(3)

摘 要

铁路超限货物运输对于满足国家大型工程项目和国防建设的运输需求具有十分重要的意义，它将占据越来越重要的地位。

超限货物车运行条件复杂，装有超限货物的车辆在接近沿线建筑物或设备时往往需要限制运行速度，甚至停车后再起动慢行通过；在复线线路上与邻线列车交会时往往需要限速，甚至禁止会车。因而超限货物运输占用线路的能力多，对正常的运行秩序干扰大。

在此背景下，本文从超限货物运输特征和运输组织出发，研究了超限货物运输的特点，对超限车挂运方案选择的影响因素进行了分析。采用模糊综合评价法构造超限车挂运方案优化模型，将影响挂运方案的定性、定量因素协调统一起来，以模糊综合评价结果向量作为判定标准，选择整体效益最优的超限货车挂运方案，为超限货物运输组织者提供决策支持，同时以上海铁路局管辖内金华东站的超限货物运输情况作为实例，利用优化模型对其超限车挂运方案进行优化，得出最优超限车挂运方案。

Abstract

Railway out-of-gauge goods transportation is of great significance to satisfy the transportation demands of large-style engineering project and the construction of national defense, Railway out-of-gauge goods transportation will occupy an increasingly important role.

Out-of-gauge goods wagons runs conditions of complex, in general, some trains with vehicle loaded with out-of-gauge goods must run more slowly than other trains when the trains approach the buildings and equipment near the railroad or meet trains on adjacent lines. In some case, they cannot meet trains on adjacent lines. Out-of-gauge goods transport occupies more capacity of lines and railway operational scheme is affected. Against this background, this article, based on the theory of out-of-gauge transport characteristic and transport organization, analyzing the factors affecting of the picking up and transport program. Using fuzzy comprehensive evaluation method to construct the optimization model of the picking up and transport program integrates the qualitative and quantitative factors affecting. Use of fuzzy comprehensive evaluation result vector as the criterions and then chooses the optimum program, Providing decision support for the organizers of the gauge freight transport .And using out-of-gauge goods transport situation in Jinhua east station within the jurisdiction of the Shanghai Railway Bureau as an example , the use of the optimization model for its overrun car linked to transport program to optimize the obtained optimal overrun car linked to the transport program.
