| dc.description.abstract | With the increasing demand for transportation, mass transportation must not only satisfy people′s needs, but also attach importance to the safety experience. The operation of the MRT system must be synchronized with the maintenance and consideration. The equipment can maintain it in good condition and reduce the risk of failures through maintenance operations. The MRT platform screen doors serve as barriers to the safety of passengers and trains, and the maintenance cannot be ignored. The operation management facilitates the maintenance operation by scheduling. In practice, the scheduling is made mainly based on the personal experience of the decision maker, which lacks the perspective of system optimization. Therefore, this study takes the approach of system optimization and develops models for the maintenance scheduling of MRT platform screen doors, hoping to effectively assist business operators in deciding optimal scheduling.
In this study, preventive maintenance scheduling models for MRT platform screen doors are developed, which are target one maintenance working team and multi maintenance working teams. And the time-space network flow technique is utilized to formulate the potential movements of working teams among all stations in the dimensions of time and space. The objective is to minimize the total working time. The C computer language, coupled with the CPLEX mathematical programming software, is employed to solve the problem. In order to evaluate the performance of the models, the numerical tests using real data from a domestic MRT company are performed. The results show that the proposed models and could be used in practice. | en_US |
