由於時代的進步，各式產品與服務推陳出新，競爭態勢已自原先業內競爭發展到業間競合，食品飲料業也不例外。在加入WTO後，全球化的趨勢引發了產業結構性的改變，而國內食品飲料產業之市場競爭亦日趨熾熱。本篇論文擬探討食品飲料產業在面對劇變的競爭下，該如何運用決策支援資訊系統來因應外在持續變化的競爭環境。
本研究透過對個案公司重要的決策關鍵人物，以深入訪談方式及問卷資料分析整理後，藉由DeLone and McLean的資訊系統的成功模型，來探討個案公司導入決策支援系統的關鍵成功因素。本研究結果不僅提供個案公司日後經營管理的依據，更將讓食品飲料業發展決策支援系統之歷程與經驗，有系統的整理出來，以提供往後接續之研究參考。
關鍵字：食品飲料業、決策支援資訊系統、關鍵成功因素、資訊系統的成功模型。

As time progress, introduce new kinds of products and services, competition has been the development of competition to the industry since the original inter-competing industry, food and beverage industry is no exception. After joining the WTO, globalization led to changes in industrial structure, while the domestic food and beverage industry has become increasingly intense market competition. This paper was to explore the food and beverage industry in the face of dramatic changes in competition, how to use decision support information systems to constantly changing in response to external competitive environment.

Through a case study companies in this key decision makers in order to in-depth interview and questionnaire data sorted and analyzed by DeLone and McLean information systems success model to study the decision support system for the individual company's critical success factors. The results of this study not only provides case management company in the future based on, but will allow food and beverage industry, Decision Support System development process and experience, a systematic study of them, in order to continue the study for future reference.

Keywords: food and beverage industry, the decision support information systems, critical success factors, information systems success model.
