铁路客运站候车区运用方案优化方法和模型

Method and Model for Reasonable Use of Railway Passenger Waiting Compartment

候车区是铁路客运站内旅客聚集密度最大、停留时间最长的区域,其合理运用对提高客运站的运输组织效率有着重要的作用。文章对铁路客运站候车区车次分配问题建立了基于三目标的数学优化模型(优化的3个目标分别是:一个候车区在同一时间只能被一个车次占用、便于旅客进站上车、保持候车室运用和负荷均衡性),并对该模型进行算法设计和求解。通过实例验证和参数微调对比,对候车室运用方案的优劣进行了评价,验证了数学模型和算法的正确性。

Waiting compartment is one of the most significant facilities in railway passenger station.It accommodates most of passengers in railway passenger station.Besides,passengers also stay here for a long time.Therefore,making reasonable use of it is very important in improving the efficiency of passengers transport organization.In this paper,a multi-objective optimization model for utilization of railway waiting compartment is established for three objectives including: passengers of a train occupying the only waiting compartment at the same time,minimizing the distance of passengers and balancing the utilization of waiting compartment.Furthermore,the algorithm of the model is designed and solved.With the example verification and parameter adjustment,the paper evaluates the operation plan's advantages and disadvantages,and verifies the correctness of the mathematical model and its algorithm.
