摘要
如何编制列车占用到发线计划 ,是铁路车站作业计划编制过程中一个关键问题。本文通过分析车列占用到发线时区集合的特点 ,提出到发线运用安排图论模型 ,将到发线运用问题转化为图的 k-顶点着色问题。然后将模拟退火算法运用于该问题 ,最后给出了相应算法实例.
The key problem of how to make the plan of using arrival and departure lines in the process of making operative plans for reilway district station is studied in this paper. We construct the model of using arrival and departure lines for railroad district station, and convert it into the problem of k-vertex graph coloring. We exploirt the method solving the problem with simulated annealing algorithms. Finally, an example is given.
