定点集结是一种高效率的集结方式,有利于运输质量的提高,其解体顺序的确定是阶段计划的关键问题,优化解体顺序可以有效节约中时,组流上线。本文比较定点集结模式与定编集结模式的优缺点及适用性,进一步分析放宽条件定点集结模式对于解体顺序优化的影响,建立放宽条件定点集结模式下的解体顺序优化模型,模型利用编组站能力、作业时间标准、最小编成辆数等作为限定条件,以有调中时最短作为目标函数进行车流推算,并采用遗传算法得到满足条件的最优解体顺序。以丰台西编组站上行系统为例进行模型的实际应用,验证了模型的有效性。
Fixed-point assembly is a highly efficient assembly method, which is conducive to the improvement of transport quality. The disassembly sequence is the key issue of phase planning. Optimizing the disassembly sequence can effectively save time and streamline the flow. This article compares the advantages and disadvantages of the fixed-point assembly and fixed-assembly methods and their applicability. The paper further analyzes the effect of relaxed fixed-point assembly on the optimization of disassembly sequence, and establishes a disassembly sequence optimization model under the condition of fixed-point aggregation. Time standard, the minimum number of vehicles compiled as a limited condition, with the shortest time as the objective function of traffic flow calculation, and the use of genetic algorithms to obtain the optimal conditions to resolve the order. Taking Fengtai West Marshalling Station uplink system as an example, the practical application of the model is verified, and the validity of the model is verified.
