The invention discloses a subway departure scheduling method and system, and the method comprises the following steps: obtaining passenger riding information, line information and regular train information, and building a subway environment state matrix; obtaining metro reward and punishment data, and establishing a departure decision output by metro reward and punishment for judging a departure effect and generating a new departure decision; predicting a new environment state matrix at the next time point according to the subway environment state matrix and the riding information, and updating a departure decision output by the subway reward and punishment; inputting the subway environment state matrix and the reward and punishment data at each time point into a convolutional neural network for training, outputting a train departure decision after training, and executing subway departure according to the train departure decision. According to the method and the system, a Policy gradient algorithm is adopted to carry out reward and punishment output according to a subway environment state, intelligent optimization of subway scheduling can be realized, and an output result of output subway scheduling can more accord with a humanized design in combination with a convolutional neural network.
