A study of network optimization model and algorithm for carrying capacity of station throat

随着铁路运输全面走向市场 ,列车全面提速 ,开行种类更加丰富多样 ,开行时间、作业方式等变动更加频繁 ,这使得车站咽喉作业能力的动态复杂性更加突出。同时 ,为满足既有铁路扩能、提速改造的需要 ,对车站咽喉作业能力的评价、设计应有准确的把握和先进的操作手段。论文运用图论和网络优化技术对车站咽喉布置、咽喉及车站作业过程进行抽象建模 ,建立车站咽喉作业占用安排网络优化和咽喉作业能力复合递阶决策模型 ,以及模型实现的计算机算法。

With the railway transportation opening for the market, the travelling speed of large number of trains becoming faster, and the kinds of trains, operation styles and time arrangement being more variable, the dynamic complexity of the operation capacity of railway station throat pops out than ever before. Thus, in order to meet the requirements of railway upgrading and evaluation, the advanced and accurate methods and tools are needed. This paper models the layout and configuration of the station throat and operation processes. The network optimization model of throat operation arrangement and the compound staged decision model of throat opration capacity are presented. Furthermore the computer based algorithms for the models are given out. At last, the models and algorithms are justified with the calculation results of simulation for the practical operations.
