dc.description.abstract | Along with the economy flourishes development, a lots of people move in the metropolis area. In order to solve the gradually serious traffic congestion problem, decision makers adopt public transportation-oriented policies in most metropolitan areas at present. While developing MRT system positively, its maintenance and the quality control are quite important, in which electric multiple unit (EMU) system is rides in a carriage the security the direct matter to the passenger, therefore its overhaul and maintenance is not allowed to ignore. When carries on the electric multiple unit maintenance scheduling, in the practice mostly admired formerly is artificial experiences. However this policy easily makes method lacked the overall systematic characteristic to appraise. Hence this study viewpoint of by the system optimization, develops model for the maintenance scheduling of electric multiple unit, expected can provide the policy maker in deciding optimal scheduling the assistance.
In this study, we employ rolling analysis to make dynamic decisions and the mathematical programming, take the objective of minimizing the total manpower hours and in satisfies under the practice correlation limiting condition, to constructs the electric multiple unit maintenance scheduling model. In the solution aspect, we use the CPLEX mathematical programming software coupled with the C++ computer language to solve the problem. After all, we appraise the achievements of this model. The numerical tests using real data from a domestic MRT company are performed, and aims at the different parameter to carry on the sensitivity analysis and the plan analysis. The results showed that this research propose model could be utilized in the practice effectively. | en_US |
