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.
