摘要:

制定铁路线路养护维修计划既要保证线路充分维修,又要兼顾经济效益.为此,以区域路网为研究对象,建立了基于整数规划的铁路线路养护维修计划优化模型.模型考虑了路网中线路之间维修资源的约束,以维修时间和股道占用状态为决策变量,以股道占用费用、维修费用及惩罚费用总和最小化为目标,通过集中安排线路中各项养护维修活动节省维修支出,减少维修活动对股道的占用时间进而达到优化目的.基于启发式算法设计了模型求解方法,仿真实验结果表明,模型具有较好的实用性,能够为编制铁路线路年度养护维修计划提供决策支持.

Abstract:

Scheduling railway maintenance should guarantee both sufficient maintenance and economic benefit. Therefore, taking regional railway network as research object, this paper develops an optimization model of railway maintenance plan based on integer programming. Considering the constraint of maintenance resources for lines in a regional railway network, the maintenance time and the condition of track possession are used as decision variables, and the minimum total cost of track possession, maintenance and penalty are used as target function in this model. The track possession time is reduced, and the optimal objective achieved finally with scheduling all the maintenance activities clustered. The simulated results based on the heuristic algorithm indicate that the proposed model is strong adaptability and can provide decision support for scheduling annual railway maintenance in a network.

Key words: railway transportation, maintenance plan, integer programming, optimization model, heuristic algorithm
