The invention relates to an urban rail transit train operation adjustment scheme optimization method and system. The method comprises the following steps: 1, constructing a rail transit train operation element constraint; 2, carding common train operation adjustment strategies, and abstractly expressing the common train operation adjustment strategies as mathematical formulas; 3, establishing a train operation adjustment scheme optimization model; and 4, solving the model by combining a greedy algorithm with a train timetable calculation method to obtain a train operation adjustment scheme. According to the method, urban rail transit train operation process elements and common operation adjustment strategies are abstracted into mathematical models, and compared with a mode of formulating a scheme mainly according to artificial experience in the current reality, the operation adjustment scheme obtained through a quantitative optimization mode is more scientific and reasonable. The method focuses on the typical'line traffic capacity decline 'scene in the actual operation process, the train operation constraint is considered in detail, and the applicability of the adjustment scheme is fully ensured. And the high timeliness requirement of train operation adjustment under emergencies can be met.

    本发明涉及一种城市轨道交通列车运行调整方案优化方法和系统。方法包括:1、构建轨道交通列车运行要素约束;2、梳理常用的列车运行调整策略,抽象表达为数学公式;3、建立列车运行调整方案优化模型;4、以贪心算法结合列车时刻表推算方法,对模型进行求解,得到列车运行调整方案。该方法将城市轨道交通列车运行过程要素以及常用的运行调整策略抽象为数学模型,相比于目前现实中主要依据人工经验制定方案的方式,通过定量优化的方式求解得出的运行调整方案更加科学合理。该方法重点关注实际运行过程中典型的“线路通行能力下降”场景,详细考虑了的列车运行约束,充分保证调整方案的适用性。能够满足突发事件下列车运行调整的高时效性需求。
