多機廠捷運路網兩階段列車排點分析方法

A Two-Stage Method for the Construction of Multi-Depot MRT Timetables

捷運系統列車排點(timetables construction)乃拍在現有軌道設施、廠站配置及控制系統等環境下，運用既有車隊規模排定合適班表(timetable)，以做為設定列車自動控制(ATC)及相關車輯、人員排班作業之基礎。本研究皆在延續蘇昭銘等人[民90]針對單一路線、單一機廠捷運*統環境所進行之列車排點研究，將多機廠及路網之特性納入分析方法中。由於在路網環境下需考量不同路線令併點之列車銜突;而多機廠之環境則除需考慮、個別機廠併入點衝突外，尚需加入個別機廠容量限制、營運收發車平衡及尖離峰轉換時段增減車輛來源等多項因素，將大幅增加分析之複雜度與困難度，因此本研究結合收發車策略之故發式求解法及調整街突之數學規劃模式，建立多機廠捷運路網之捷運系統之兩階段列車排點分析方法，並以台北捷運系統之淡水線、中和線及新店線為實例研究對象，測試結果發現本研究所產製之班表不論在班距符合率或是變動幅度等評估指標，均優於具有實務經驗專家所排定之班表，將有助於解決未來各大都會區捷運系統陸續通車營運後之列車排點作業。

The timetables construction of mass rapid transit system is to use the existing vehicle facilities of rails, station location and control system to generate a suitable time table for ATC (automatic train control) and the relevant vehicle and staff. The purpose of our research is to extend Jau-ming Su's study ofthe timetables construction on the single line and single depot in mass rapid transit system to the multiline and multidepot. The multiline environment needs to consider conflicts of vehicles occurrence in different lines at junction points and the multidepot should consider vehicles from a depot entering master line, while the multidepot capacity confinement of individual depot, the balance oloperation vehicles and the increase or decrease of vehicles when peak hours transler to off-peak so that these causes have substantially increased the complication and difficulties for the analysis. Therefore, our study integrates Heuristic Algorithms of strategy oloperation vehicles and mathematical planning model of adjusting conflict of vehicles to develop the timetables construction analytic process of mass rapid transit network. This study has been implemented in Tamshui, Chungho and Hsintien Line in Taipei, and the result shows that through the analysis process it not only creates a suitable timetable but also will help to solve timetables construction of mass rapid transit in every city in the future.
