In practice, the scheduling of preventive maintenance for MRT platform screen doors in Taiwan is usually done manually by planning personnel, re-lying on their experience and past operating records. This method is not only time-consuming but also lacks effectiveness and efficiency. When the oper-ational environment changes, the scheduling must be redone, further increas-ing the time required. To address this issue, we apply network flow tech-niques to develop a preventive maintenance scheduling model for MRT plat-form screen doors in Taiwan, with the objective of minimizing the total working time, subject to the related operating constraints. The model is for-mulated as a binary integer network flow problem with side constraints and the C computer language, coupled with the CPLEX mathematical program-ming software, is employed to solve the problem. Computational tests, along with sensitivity analyses, are performed using data from Taiwan’s MRT com-pany. The results demonstrate the effectiveness and usefulness of the pro-posed model in scheduling preventive maintenance for MRT platform screen doors in Taiwan. |
