| dc.description.abstract | A good maintenance plan can help Taiwan Freeway Traffic Center to efficiently perform maintenance so as to ensure its safety and travel punctuality. However, in the past ， maintenance scheduling tasks were mostly performed by staff based on experience, which is not only time-consuming but also ineffective in meeting the maintenance requirements,This result in waste of manpower. There was very little literature discussing such problems in the past. Although a preliminary research was carried on recently, and practical strategies were not considered, limiting its effect in practice.
In this research, mathematical programming techniques and computer algorithms were used, incorporating and developing suitable models and solution methods, in order to help Taiwan Freeway Traffic Center efficiently and effectively plan their maintenance schedules and manpower supplies.
First a basic model was developed to several strategic models . These models are formulated as mixed integer programs. Since their problems can be optimally solved in a reasonably short time, A solution algorithm was used to solve the problems. LINGO system was used to code all necessary programs and apply the mathematical programming solver, as well to develop the solution algorithm. Finally, to evaluate the models and solution algorithm, A case study using the real operating data from a major Taiwan Freeway Traffic Center was used. | en_US |
