軌道車輛產業選擇供應商評估之研究

Abstract

軌道車輛產業係由機械、電機、號誌、通信與資訊工業等高度整合性工業，該產業可以分為三類：軌道車輛製造業、零件業及維修業等。 該產業全部只有130多家，其中屬於製造業的只有5家。此5家必須仰賴其餘120家專業技術、品質保證，供應商提供技術支援，品質合乎國際標準或軌道車輛規範，因此技術支援、品質認證變成此產業的特殊因素。 問卷調查採用電子郵件方式，讓受訪人員可以直接傳寫完畢，由於母體數目太小，回收數量不多的情況下，因素分析的適合性檢驗不明顯，因此沒有辦法決定層級數目，改採項目分析法來刪除不需要的因素，並利用層級分析法(Analytical hierarchy process)與Belton & Gear兩位學者所修正AHP方法分別對製造業與零件業建立選擇供應商評估模式。 本研究的具體結果，包括(1)該產業選擇供應商之評估因素與其模式(2)探討該產業製造業與其零件業兩者評估因素與模式之差異(3)對兩者分別提出可行的建議，以提升競爭力。 關鍵字：評估因素、評估模式、層級分析法。

The railway industry is high integrated by mechanical, electric machinery, signal, communicatory and information industry. It can be classified into three parts: railcar-manufactory industry,railway-assembly industry and railway-repair industry. There are more than 130 factories with 5 railway-manufactories only. They rely on technologies from suppliers, international quality and reliability standards. Thus technologies, quality and reliability are the special factors of this field. The investigation in this research is made by E-mail questionnaire. This research use analysis to delete some unnecessary factors and Analytical hierarchy process and Belton & Gear modified AHP to build a supplier rating model. The results include of (1)The model and factor of rating suppliers.(2)Probe into the difference model and factors of between railway-manufactory industry and railway-assembly industry.(3)Bring up workable recommends to both of them. Keyword : factor, model, Analytical hierarchy process
