摘要: 提出了不成对机车周转图的一种铺画方法, 在机车折返站, 运用网络流模型确定出不成对机车周转图上满足最优化要求的基本成对机车周转图方案, 为未获指派的机车就近勾画交路。在基本段所在站, 将附挂回送机车的运行线在该站的运行时刻插入相应的时刻序列, 将基本段所在站不成对机车周转图问题转化为成对机车周转图问题, 利用表上寻优算法求解成对机车周转图交路方案。分析结果表明: 对不成对系数为0.78、两端站机车停留时间标准相同的机车周转图, 计算得到机车在基本段所在站总停留时间与折返段所在站总停留时间之比不小于1.25, 该算法将机车在折返段的额外停留时间最大限度地转移到基本段, 满足了机车在折返站紧凑折返的要求。Abstract: One kind of plotting algorithm of unpaired locomotive working diagram was discussed. At locomotive return station, the network flow model was applied to figure out the scheme of paired locomotive working diagram, the diagram meeted the optimal requirements on unpaired locomotive working diagram, and could assign residual locomotives to their nearest train paths respectively. At locomotive home station, the departure or arrival time of train path with extra return locomotive was inserted into the list of train departure or arrival time, and the unpaired locomotive working diagram was transferred to paired locomotive working diagram, and the assigning problem of paired locomotive working diagram was solved by using searching-optimization-at-form method.Analysis result shows that when the unpaired factor is 0.78, and the locomotive staying time standards at both of station ends are same, the proportion between the general staying time of locomotive home station and that of locomotive return station is no less than 1.25. The extra staying time of locomotive at return station is further transferred to home station by using the optimal algorithm, so the locomotive can compactly return at return station.
