The Model and Algorithm of Route Decision in Out-of-gauge and Enhanced-load Freight Transportation

分析超限超重货物运输路径选取的特性将整个铁路路网划分为4层,建立在路阻限制、桥隧综合限界、区段限制等因素下的单层和多层路径决策模型,并为该模型设计了相对应的单层和多层路径决策算法。通过基于超限超重货物运输决策支持系统的电子地图子系统实验,表明该算法是有效的。

Considering the characteristics of route decision in out-of-gauge and enhanced-load freight transportation, the paper proposes to divide the whole railway network into 4 levels and establishes the decision models of monolayer route and multi-layer route under the constraints of roadblock, bridge integrated metro gauge, section limitation. It designs the corresponding algorithms for monolayer route and multi-layer route decision models. Through the experiment of electronic map subsystem of out-of-gauge and enhanced-load freight transportation decision support system, it can be drawn that this algorithm is effective.
