为充分利用高速铁路列车密度大的规模效应灵活编制乘务交路,提高乘务间休时间和减少外段过夜次数,研究固定区段轮乘制下高速铁路列车乘务交路计划的编制问题。建立以乘务交路总接续费用和过夜费用最小的双目标优化模型,并采用改进的蚁群算法求解。以京沪高速铁路本线和部分跨线列车为研究对象,对比研究现有乘务模式与固定区段轮乘制乘务模式的优劣性。研究结果显示:所有方案中,原乘务方案所需乘务组数最少;2个分界点方案过夜次数最少;所需乘务组数随着分界点的增加而增加。
In order to make full use of the large-scale effect of high-speed railway trains on the large-scale effect of expressways, it is necessary to flexibly formulate crew intercourse, increase the inter-crew rest time and reduce the number of overnight stayings, and study the compilation of high-speed railway train schedules. A dual-objective optimization model is established, which takes the total connection cost and minimum overnight cost of service delivery, and uses the improved ant colony algorithm to solve the problem. Taking Beijing-Shanghai high-speed railway line and some cross-line trains as the research object, the advantages and disadvantages of the existing passenger service mode and the fixed service ride mode are comparatively studied. The results show that the original crew scheme requires the least number of crew units in all the schemes and the minimum number of overnight sets in the two boundary schemes. The number of required crew groups increases with the increase of the boundary points.
