Urban rail transit emergency intelligent scheduling method and system

The invention discloses an intelligent scheduling method and system for urban rail transit emergencies. The method comprises the following steps: S1) constructing a computational graph according to historical data of the urban rail transit emergencies; s2) instantiating the calculation graph to obtain an instantiated calculation graph; s3) constructing a train intelligent scheduling optimization model based on the instantiation calculation graph; s4) solving the train intelligent scheduling optimization model to obtain a train scheduling command decision scheme; and S5) the train dispatching command decision scheme is issued to an automatic train monitoring system for execution so as to realize intelligent dispatching of urban rail transit emergencies. Under the condition of emergencies, compared with a traditional dispatcher manual management and control method, the train operation can be dispatched more accurately and scientifically, and the handling efficiency of the emergencies is ensured; an intelligent
