捷運系統短期電聯車維修排程最佳化

OPTIMAL SHORT-TERM MAINTANENCE SCHEDULING OF ELECTRIC MULTIPLE UNITS IN AN MRT SYSTEM

摘要


目前實務上在進行短期電聯車維修排程作業時,大多依據決策者以往經驗,然而此決策方法缺乏系統性整體分析。緣此,本研究以系統最佳化的觀點,考量實際的營運限制,並以總人力小時最小化為目標,運用數學規劃方法,構建一短期電聯車維修排程模式,且利用CPLEX數學規劃軟體求解模式。此外,本研究透過滾動分析方式,運用模式進行動態維修排程決策。最後,為適當地評估模式之績效,本研究參考國內某捷運公司的營運並做適當假設以產生資料進行測試。測試結果良好,顯示本研究之模式應可提供捷運系統業者作為短期電聯車維修排程規劃時之參考。

並列摘要


In practice, currently electric multiple unit maintenance scheduling in short-term operations is generally performed with the decision maker’s experiences, which lacks a systematically integrated analysis. Therefore, based on the viewpoint of system optimization, this study considers the practical operating constraints, coupled with the objective of minimizing the total manpower-hours, and adopts the mathematical programming method to construct a short-term maintenance scheduling model for electric multiple units, which can be solved using the mathematical programming software CPLEX. Besides, this study adtops the rolling analysis approach to deceide on the maintenance schedules dynamically. Finally, to suitably evaluate the model, this study performs a case study using real data with suitable assumptions from a domestic MRT company. The test results are good, indicating that the proposed model could be useful references for MRT companies in short-term EMU maintenance scheduling.
