%X 摘要 优化到达列车的解体顺序和出发列车的编组顺序是编组站作业计划的核心内容之一.基于车流接续与分配方案，构建综合考虑解体顺序和编组顺序的优化模型，包括单溜放驼峰、峰尾一台调机情形，多台解编调机情形的解编顺序优化模型.所构建模型还可进一步扩展至考虑列车技术检查顺序的优化.最后设计案例验证模型的正确性，通过对不同数量解体调机、编组调机情形的列车解编顺序优化的测算可知：受车流量的影响，双推双溜的作业效率不一定比双推单溜高；解编作业相互影响，两者的作业能力也应相互协调，只增加解体作业能力或者只增加编组作业能力对整个系统作业效率的影响较小.<br>Abstract：Daily operation of marshalling yard mainly focuses on optimizing the hump sequence of arrival trains and assemble sequence of departure trains. Based on the wagon-flow allocation plan, this paper presents two sequencing models of hump and assemble, such as the sequencing model with one hump engine and one-yard engine, as well as a general model with multi-engines, which can be improved to take the optimization of technical inspection sequence of trains into consideration. At last, numerical examples are proposed to verify those models. The calculation results of different numbers of shunting engines show that the efficiency of parallel hump process does not always better than single hump process and the hump sequence and assemble sequence are interacted, and the capacities of two parts should be coordinated with each other. The efforts on the efficiency of the whole dispatching system appears insignificant, if only the capacity of the hump side or assemble side is increased.
