分析定位式作业客运站调机应遵循的条件和目标,建立定位式作业客运站调机运用优化的多目标、非线性、混合0-1规划模型,对车站各系统间协调作业这一定性问题进行定量化描述。根据模型特点,基于分层序列法思想,将模型分解为成组作业方案优化、调机作业顺序优化、调机作业时间优化3个子模型,建立定位式作业客运站调机运用优化多层决策模型。针对多层决策模型的特点,设计定位式客运站调机作业计划的多层蚁群优化算法。

Based on the detailed analysis of the conditions and objectives of the shunting engines used in locationoperation mode in passenger station, the multi-objective nonlinear 0-1 mixed optimization model for the opera- tion of the shunting engines was established to describe the coordinated operation between subsystems of passenger station quantitatively. Based on the characteristics of the model and hierarchical sequence method, the model was decomposed into three sub-models, which are separate optimization group operation program, order and time for switching service, whereby the multi-layer decision-making model for the optimization of the operation of shunting engines in location-operation mode was established. In response to the characteristics of the multi-layer decision-making model, a multi-layer ant colony optimization algorithm was desiged for the switching service plan in location-operation mode passenger station.
