建立整数型轨道状态最优综合维修计划模型

Foundation of the optimized comprehensive Integral track maintenance plan model

为实现高效的轨道不平顺养护维修,建立最优养护维修计划模型和采用大型养路机械进行作业是十分重要的。本文以养护维修时间为决策变量,以年度轨道不平顺平均值最小为目标函数,在考虑了一系列约束函数的情况下,建立了整数型轨道状态最优综合维修计划模型。该模型能有效利用现场的养护资源,从安全和舒适的角度出发来制定养护计划,该模型的建立从理论上解决了轨道不平顺状态计算机辅助决策系统的关键问题。

In order to realize efficient maintenance of track irregularity, it is necessary to establish the optimized maintenance plan model and adopt large scale machineries to maintain railway tracks. In this paper, the optimized comprehensive integral track maintenance plan model is established in consideration of a series of restriction functions, and the maintenance time is used as the decisionmaking variable and the minimum mean annual value of track irregularity as the target function. This model can take full advantage of site maintenance resources, and help make maintenance plans from the angle of safety and comfort. Its foundation resolves the key problems of the track irregularity computeraided decisionmaking system in theory.
