石化工業是我國極為重要的基礎工業，其關聯製品涵蓋上游基本原料、中游中間原料至下游加工製品。依據經濟部工業局的統計，石化工業之總產值已超過12000億元，約佔製造業總產值之23%'故對國內經濟民生有相當重大的影響。近年來，全球石化產品的需求逐漸回暖，使石化原料需求快速成長，因此，石化專區必然成為兩岸積極推動的重點建設。目前石化業建廠，大多採統包模式，以提昇建廠效率，但由於統包商的遴選並無嚴謹的機制，且一般採最低價標，故統包商素質易參差不齊，部分案例設計與施工品質產生瑕疵，造成運轉不順利，並產生龐大維修費用。因此，如何選取優良可靠的建廠統包商，實為建廠成功與否的重要關鍵。本研究針對石化業評選建廠統包商，蒐集國內外學者、機構、公共工程等相關學術文獻及國內某石化集團等關聯產業之建廠實務著作，進行深入分析研究，以探討石化業建廠要素、公共工程等選商要素與石化業建廠統包商評選因素之關聯性，並利用彙整後之關聯因素，進行專家意見調查及問卷設計，問卷回饋的結果進行因素分析，以建構石化業建廠統包商評選之層級架構，再以層級分析法(AHP)進行評選因子之權重分配，進而建立嚴謹可行之評選機制。此研究之結論可供石化業經營者參考，並據以選擇出優質之建廠統包商。

Petrochemical industry is one of the most important primary industries in Taiwan. Products of this industry comprise headstream basic parts, middle stream medial parts, and down stream processing wares. According to Industrial Development Bureau (IDB), the total production value of petrochemical industry has exceeded 12000 hundred millions NT dollars, with the percentage standing at approximately 23% of the whole manufacturing industry. Therefore, it enormously affects the domestic economy. In recent years, global demand on petroleum chemicals is growing. The ongoing attempt to carry out the tenth five-year plan from the mainland China specifically and especially stimulates the rapid growth of the petrochemical industry. Building a petrochemical industrial park is becoming the priority construction across the strait. Currently, to ensure the plant-building efficiency, most petrochemical plant constructions adopt the design-build mode. In the past, on the contrary, since there were no formal and strict criteria for plant builder selection, quality of builders differs tremendously, such as producing flaws in certain design cases, making untoward operations, and creating tremendous cost in maintenance and resulting in huge waste. In light of the unsuccessful past domestic plant-building experiences, selecting a reliable design-builder is a key factor for petrochemical plant to finish construction without a hitch. This paper focuses on plant-building design-builder selection criteria for the petrochemical industry and analyzes in depth all relevant documentations, either domestic or abroad, regarding scholars, institutes, and public projects, and other related writings concerning plant-building practices from a certain petrochemical firm in Taiwan to discuss the correlations of petrochemical plant-building factors, builder selection factors of public projects, and design-builder selection criteria for the petrochemical plant construction. Based on the correlations established, expert interview is conducted, questionnaire is designed, and factor analysis is conducted to establish the criteria hierarchy. Then, the Analytic Hierarchy Process (AHP) is applied to determine each criterion weight and to establish a strict but feasible selection criteria mechanism. The results of this study may serve as a reference for managers of petrochemical industry in choosing the best plant-builder.
