純檢修資格航機修護人力供給模式之建立

A MODEL FOR AIRCRAFT MAINTENANCE MANPOWER SUPPLY OF UNIFORM CERTIFICATES

對航空公司而言，如何使航機修護工作能有效率且確實，以確保航機在飛行中的安全，並能配合該公司營運飛航班表的準時起降，是一項重要的課題。傳統航空公司維修部門對於修護人員的排班上，係基於人工經驗，以簡單的排班及輪班規則進行修護人員的排班。此排班方式除費時外，往往無法與實際營運所需的修護需求相配合，易導致人力供需不均衡的現象。本研究針對純檢修資格的航機修護人力供給問題，構建一整數規劃模式，並運用 CPLEX套裝數學規劃軟體求解模式，以期幫助航空公司的修護部門有效率地規劃修護人員之排班。最後，本研究以國內之一航空公司實際的修護資料為例，進行模式之測試與分析，初步結果顯示模式的效果良好。

It is essential for airlines to efficiently perform aircraft maintenance in order to ensure aviation safety and punctuality. In tradition, the maintenance scheduling, based on staff's experiences, was performed using a simple rule, which is not only time-consuming but also ineffective. In particular, the resulting manpower supply does not easily meet the minimum requirements, possibly causing imbalance between supply and demand. In this research, we develop an integer programming model and use the mathematical programming solver, CPLEX to help airlines efficiently and effectively plan their aircraft maintenance schedules and manpower supplies of uniform certificates for examining a set of aircraft types. Finally, to evaluate the model developed in the research, we perform a case study using the operating data from a major Taiwan airline. The preliminary results show that the model could be useful.
