Method for optimizing bogie procedure in advanced repair of motor train unit and planning and scheduling method and system

Abstract

The invention discloses a method for optimizing a bogie procedure in an advanced repair task of a motor train unit and an advanced repair planning and scheduling method and system for the motor train unit. The advanced repair planning and scheduling method for the motor train unit includes the steps of receiving a scheduling time period and an advanced repair task in the time period, determining space overhaul capacity of a motor train with the advanced repair task, determining total time and work load in a unit time in the bogie procedure in advanced repair programs corresponding to vehicle types in the advanced repair task, determining the time when the motor train unit enters a warehouse in the advanced repair task, building a mixed integer programming model of the advanced repair program of the motor train set on the basis of the scheduling time period, the advanced repair task, the total time and the work load in a unit time in the bogie procedure and the time when the motor train unit enters the warehouse, and calculating a feasible solution of an output model. The plan of the advanced repair of the motor train unit can be efficiently made, and existing overhaul spaces and equipment can be made use of to the largest extent by means of the advanced repair task of the motor train unit.

Description

technical field [0001] The invention relates to the technical field of high-speed railway construction, and in particular to a process optimization method for high-level repairing bogies of EMUs, a method and system for planning and scheduling advanced repairs for EMUs. Background technique [0002] At present, my country's high-speed railways, subways and intercity railways in major cities are all under rapid development and construction. With the continuous expansion of the operation scale of EMUs and the continuous accumulation of running kilometers, in order to ensure the rapid and efficient operation of EMUs, it is necessary to carry out maintenance of EMUs. [0003] In view of the short operating time of EMUs in my country, maintenance operations are mainly arranged according to the regular maintenance mode. Periodic maintenance According to the technical parameters such as the traveling kilometers or running time of the EMU, the EMU maintenance plan is formulated in ...

Problems solved by technology

Under the premise that it is currently impossible to expand the maintenance site or provide sufficient equipment, how to reasonably arrange advanced maintenance tasks to maximize the use of existing maintenance sites and equipment has become a breakthrough point to solve the above contradictions

[0006] The existing high-level maintenance plan for EMUs is mainly based on the traditional manual preparation method, which cannot meet the needs of advanced maintenance tasks that are constantly changing with the EMU operation plan, and the complexity of advanced maintenance determines that the advanced maintenance plan manually compiled cannot take into account Various constraints, maximize the use of existing maintenance sites and equipment
