编制新旧交替列车运行图客车车底周转图的实质是确定新运行图中所需客车车底的来源与旧运行图中所运用车底的去向,以实现新旧列车运行图的顺利交替。探讨交替期客车车底周转图的约束满足优化问题模型及其智能求解算法。模型以减少停运列车数量为目标,以车底技术作业时间、车底上下线地点为车底配属站等作为约束条件。利用启发式知识设计智能求解算法,得出新旧交替列车运行图客车车底周转图的满意解。
The preparation of new and old alternate train operation chart The essence of passenger car turnover chart is to determine the source of the required passenger car bottom in the new operation diagram and the direction of the undercarriage used in the old operation diagram so as to realize the smooth alternation of the new and old train operation plans. This paper discusses the constrained satisfaction optimization model and its intelligent algorithm for the turnover diagram of passenger car with alternating phases. Model to reduce the number of out-of-train as the goal, to the bottom of the technical operation time, the bottom line of the car at the end of the car attached to the station as a constraint. By using heuristic knowledge to design intelligent solution algorithm, a satisfactory solution of passenger car turnover diagram of old and new alternate trains is obtained.
