隨著台灣與中國大陸7.5 世代及 8.5世代等大尺寸面板廠之相繼設立，相關搭配面板設備及設備周邊零配件產品的潛在需求強。面板設備業者因面板大尺寸化的趨勢，使運輸成本增加，因此提升大尺寸面板設備技術與相對應零配件自主供應已成企業致勝優勢之一。
以個案公司擬發展設備周邊零配件產品-大尺寸LCD面板承載Cassette產品，即面臨到是否立即擴張問題；及受到內外環境的刺激，如現有人力及廠房資源等考量下，對於公司是否確保或喪失公司競爭力呢。藉此自製或委外決策結構、德菲法、委外的型態、影響策略性自製或委外決策要點等文獻進行探討，做為研究理論基礎。接著以供應鏈作業模式SCOR分析，剖析個案公司研究產品產業供應鏈， 分別區分上游Source(原物料、次加工材)、中游Make(製造)、以及下游(含配送)-Delivery 及Return 等供應鏈模式，其中會就是否自製或委外決策去探討中游Make(製造)作業模式，並藉由修正式德菲法(專家訪談法)，透過學者(Goehlich，2009 )所提出策略性自製或委外決策架構與評估指標，依個案公司產業特性，得出適切性高的修正後決策決策架構與評估指標，並依據修正後決策架構進行個案公司的自製或委外決策分析，以及決策後委外分析。
最後透過本研究的納入可清楚歸納出公司策略目標與相關影響因素的自製與委外關聯趨勢；以及自製與委外兩觀點，提供LCD光電面板設備產業與配合供應鏈業者，做為未來制定自製或委外決策的參考。

With the increase of 7.5 and 8.5 generation large glass substrate factories in Taiwan and China, the demand for related equipments and accessories grows much stronger. Accordingly, transportation cost is raised as a result of the trend of the large glass substrate. Therefore, strengthening large glass substrate technology and corresponding in-house supply chain are key factors in the success of business.
For example, a case company plans to develop equipment in large LCD glass substrate to carry Cassette products; however, it will confront a decision that whether to expand immediately. What’s more, with the consideration of existing human resource and factory capital, the decision determines the competitiveness of a company. First, the thesis analyzes some papers, which are related to make or buy decision structure, Delphi Method, and the effect of strategic make or buy decision, as research theoretical foundation. Second, this research intends to analyze product supply chain of some companies with SCOR approach, which includes upstream firm (Source), midstream firm (Make), downstream firm (Delivery) and (Return) models. Last, the study examines Make model by in-house production or outsourcing decision. Moreover, we conclude appropriate modified decision structure and evaluation indicator from adjusting Delphi Method, referring to strategic in-house or outsourcing structure and evaluation indicator proposed by the scholar(Goehlich, 2009), and considering different characters of the company.
Last but not the least, this research summarizes corporation strategic goal and the effect factors of the trend of in-house and outsourcing structure. Moreover, the analysis is given to TFT-LCD Equipment industry and related supply chain company for decision reference.
