Abstract
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.
