Operation adjustment method and system for metro trains under the condition of train out of service

An operation adjustment system for the metro trains under the condition of train out of service, comprising:

• an information acquiring module, configured to acquire, when a train has fault, basic parameters of a metro system, information of a train out of service and information of online normal running trains, wherein the basic parameters of the metro system comprise topological metro line information and a planned operation diagram;
• the planned operation diagram comprises train timetables and a rolling stock circulation plan;
• the information of the train out of service comprises a faulty train, train fault time, predicted time to stop service and a fault position;
• and the information of the online normal running trains comprises train service numbers, train velocities when the fault occurs and positions when the fault occurs;
• a follow-up train service and current train timetable determining module, configured to determine, according to the basic parameters of the metro system, the faulty train service out of service and the planned operation diagram, a follow-up train service set of the faulty train service and a current train timetable for each of follow-up train services in the follow-up train service set, wherein the follow-up train services comprise tracking train services of the faulty train and planned train services not started;
• a module for acquiring an adjusted train timetable of each follow-up train service, configured to adjust, according to the predicted time to stop service of the train out of service, with a minimum headway as a constraint and a minimal deviation from the train timetables as a goal, the current train timetable for each follow-up train service in the follow-up train service set to obtain an adjusted train timetable for each follow-up train service in the follow-up train service set, and determine initial adjusted train timetables;
• a module for determining earliest time that backup rolling stocks can run to the main line, configured to determine, according to the basic parameters of the metro system and the train fault time of the train out of service, earliest time that backup rolling stocks can run to the main line in the metro system;
• an adjusted rolling stock circulation plan acquiring module, configured to cancel, according to the adjusted train timetable for each follow-up train service in the follow-up train service set, the earliest time that backup rolling stocks can run to the main line, all planned train services to be executed after the fault, and the rolling stock circulation plan of the planned operation diagram, planned train services that are not executed according to the planned train timetables in the planned operation diagram, to obtain a set of planned train services to be canceled, and determine rolling stocks for executing remaining planned train services in the planned operation diagram, to obtain an adjusted rolling stock circulation plan;
• a module for acquiring information of an adjusted planned operation diagram, configured to adjust the initial adjusted train timetables according to a planned train timetable for each planned train service in the set of planned train services to be canceled, to obtain final adjusted train timetables;
• and
• an adjusted operation diagram generating module, configured to generate an adjusted operation diagram according to the adjusted rolling stock circulation plan and the final adjusted train timetables.
