| dc.description.abstract | With the rapid growth of the urban population, the demand for ＂travel＂ has increased, so governments are actively promoting the mass rapid transit system. While the MRT transportation system is in operation, the maintenance and repair of its various repair systems are also continuously carried out. In the past, the cost of the maintenance team’s travel in the road network and the cost of repairing the location of the maintenance site were mostly repaired by manual experience. The location of the maintenance site has long lacked comprehensive planning of the overall maintenance system and systematic consideration of cost resources. Therefore, in this study, from the viewpoint of system optimization, the development of the MRT maintenance site selection and the optimization model for the assignment of preventive maintenance tasks are designed to provide operators with the ability to make decisions when designing and planning maintenance site locations.
In this study, the mathematical planning method was adopted to establish the location and preventive maintenance of MRT maintenance bases with the minimum total operating cost as the target when meeting the practical emergency emergency repair time limit, site space and preventive maintenance and other relevant constraints. Task assignment mode. Due to the large scale of the problem, this study developed two heuristic algorithms to solve the problem, and evaluated the performance of the algorithm through the scheme of expanding the scale. In order to evaluate the performance of the model, this study tested the sensitivity analysis of different parameters. The results show that the model of this study can be effectively operated in practice, which can be used as a reference for the MRT company in the planning of maintenance base location and preventive maintenance task assignment. | en_US |
