因應航空交通運輸產業發展,提供新穎並具有現代化飛機技術、設計、設備與系統給乘客成為趨勢。租賃飛機為航空公司提供了根據市場變化和營運需求波動調整機隊規模、技術、系統的靈活性,同時減輕了航空公司的財務壓力,因此成為許多航空公司的機隊營運策略管理模式。然而,租賃飛機在租賃期間,除了必須遵守民航法規以確保飛機適航性之外,同時必須按照租賃合約約定的條款進行維護保養,以維持飛機價值。因此,飛機租賃週期之還機階段,飛機適航狀態與合約還機條件不符,致租賃機無法在租期終止時歸還,為大多數航空公司面臨的困境。 本研究旨在尋求租賃飛機延遲歸還之受理機制且提升還機比例。首先,以個案研究方式,分析公司修護部門執行還機前的還機檢修運作模式。其次,從修護部門組織架構上,比較了組織再造(BPR)前後兩種不同類型的運作模式:一種是功能導向的矩陣模式,另一種是任務導向的專案模式。透過分析,本研究發現專案模式的組織運作模式,可以減少專業單位和管制單位之間的作業干擾。最後,透過個案公司實例分析的運作環境下,給予個案公司建議,作為個案公司還機作業流程改善之參考。 ;In response to the development of the aviation transportation industry, providing innovative and modern aircraft technology, design, equipment, and systems to passengers has become a trend. Leasing aircraft provides airlines with the flexibility to adjust fleet size, technology, and systems according to market changes and operational demands, while alleviating the financial pressure on airlines, thus becoming the fleet management strategy for many airlines. However, leased aircraft must comply with civil aviation regulations during the lease period to ensure airworthiness, and maintenance must be performed according to the terms stipulated in the lease contract to maintain the aircraft′s value. The discrepancy between the aircraft′s condition during the return phase of the leasing cycle and the return conditions stipulated in the contract poses a dilemma faced by most airlines. This study aims to mitigate delays in returning leased aircraft and improve return efficiency. It analyzes the operational mode of the maintenance department of a case company regarding the pre-return maintenance operations. In terms of organizational structure, two different types of operational modes before and after Business Process Reengineering (BPR) are compared: one is a function-oriented matrix mode, and the other is a task-oriented project mode. Through the analysis results, it is found that the project mode′s organizational operational mode can reduce operational interference between professional units and control units. Finally, recommendations are provided for the case company based on the operational environment analyzed, serving as a reference for improving the aircraft return process.
