Abstract: Disclosed is a method for arranging parallel maintenance lines for railway wagons, including: (1) obtaining design information of the parallel maintenance lines; (2) initially designing the parallel maintenance lines; where the maintenance lines comprise a disassembly line and an assembly line parallel to each other, and the disassembly line and the assembly line are connected through a track; (3) establishing a multi-objective mathematical model for solving a parallel maintenance line balancing problem, where the multi-objective mathematical model comprises a first model for minimizing the number of workstations, a second model for minimizing an idle time of the workstations and a third model for minimizing the number of maintenance resources; and (4) obtaining a feasible solution using an intelligent optimization algorithm.
