摘要:

空车调配优化直接影响铁路运用车辆使用效率和市场需求满足的程度.从实时性优化调整角度,通过定义配空弧与装运弧,确立了配空和装运之间的映射关系,从而形成空车调配服务时空网络.在此基础上,综合考虑决策阶段内收益、成本、服务能力等因素,以空车调配收益最大为目标,构建空车调配的多时点优化模型.最后以粤东地区空车调配为案例,对所构建模型进行验证.案例结果表明,所提出的空车调配时空网络构建方法,有助于综合考虑收益、成本和点线能力等因素,以及降低问题的难度,可为空车调整策略提供新的思路.

Abstract:

Optimization of empty railcar distribution helps to improve the railcar service efficiency and meet the transportation demand. This paper defines empty railcar arcs and loaded railcar arcs from the perspective of real- time optimization, the revenue, cost and service capacity can be denoted on those arcs during the plan horizon. A time space service network of empty railcar distribution is present after mapping the relationship of those arcs. Based on the time space network, a multi- time point optimization model is proposed, with the objective of maximizing the total revenue of empty railcar distribution. At last, the model is verified by a real world example of east region of Guangzhou Railway (Group) Corporation. The result shows that the proposed time space service network and the model can reduce the difficult of the real world problem, and provide a new idea for empty railcar distribution.

Key words: railway transportation, empty railcar distribution, time space service network, multi-time point, train operation
