【摘要】 基于现场生产需求，研究动车组交路计划优化问题。首先，界定动车组交路定义，分别以交路数最少、列车接续时间最短和车底数最少作为优化方向，分析3种目标下交路计划优化的不同效果，以及动车组交路计划的限制条件；然后，以所有动车组交路所需车底数最少为主要目标、以交路总时间最短为次要目标，考虑列车接续和动车组检修等约束条件，构建车底数最小化的动车组交路计划优化模型；最后，对整数非线性规划模型进行线性化处理，并依托上海局实际列车数据，对模型开展案例研究。结果表明：该模型可灵活转换优化目标，具有较好的灵活性和通用性；相比人工交路计划，该模型得到的优化计划减少车底数1列，缩短交路总时间420min；通过模型参数的灵敏度分析验证不同优化目标间的分歧性，并得出3条交路计划优化建议分别是，在保障动车组设备安全的前提下延长检修周期、提高车站作业效率并缩短动车组在站停留时间和压缩检修作业时间。更多还原

【Abstract】 Based on the field production requirements, the optimization problem of EMU circulation plan is studied. Firstly, the definition of the EMU circulation is defined, then 3 objectives are regarded as the optimization directions including the least number of circulation route, the shortest train connection time, and the least number of train-set, under which the different optimization effects of circulation plan and the constraints of EMU circulation plan can be analyzed. Secondly, taking the minimum number of train-set required for all EMU circulation routes as the primary objective, and the shortest total time of circulation routes as the secondary objective, the optimization model of EMU circulation plan with the minimum number of train-set is constructed based on the consideration of constraints such as train connection and EMU maintenance. Finally,the linearization of integer nonlinear programming model is conducted, and case studies are carried out relying on the actual train data from the China Railway Shanghai Group. The results indicate that the proposed model can transform optimization objectives flexibly, demonstrating good flexibility and generality. Compared with the manual circulation plan, the optimized plan obtained by the model reduces the number of train-set by 1 and the total time of circulation routes by 420 min. Through the sensitivity analysis of model parameters, the bifurcation among different optimization objectives is verified, and 3 optimization recommendations of circulation plan are proposed, which are to extend the maintenance cycle under the premise of ensuring the safety of EMU equipment, to improve station operation efficiency to reduce EMU waiting time at station, and to compress maintenance operation time.更多还原
