臺灣博碩士論文加值系統

傳統科技接受模式(Technology Acceptance Model, TAM)的研究多以因素分析或結構方程模式等方法建立及驗證變數之間的因果關係，可是有些科技系統專業度與複雜度高，並非所有的受測者都完整地瞭解科技系統，而且某些變數不一定符合獨立性的假設，加上當大量樣本取得困難時，便無法正確地分析，而導致錯誤的結論。本研究為解決上述問題與假設，創新採用模糊決策實驗室分析法(Fuzzy Decision Making Trial and Evaluation Laboratory, Fuzzy DEMATEL)驗證TAM變數之間的因果關係，其亦包含計算出變數之間的相互影響程度。此方法不受限於統計方法獨立性的假設與樣本數的限制，可避免變數之間因具因果關係或樣本蒐集困難時所導致的推論偏誤，另外，Fuzzy DEMATEL採用專家意見法，可避免受測者對科技系統不完全瞭解或無完整使用經驗的問題，此外，亦可解決傳統問卷調查沒有考量人類主觀認知判斷上所具有之模糊性，而造成錯誤的判斷。本研究藉由台灣光電產業之龍頭－友達光電應用產品生命週期管理系統(Product Lifecycle Management, PLM)的個案為例，說明本方法應用於TAM的效益，研究成果將提供管理者管理以及改善解決實務上複雜難解問題的參考。
本研究發現個案Fuzzy DEMATEL方法論所建構的TAM2 模式中，除補足傳統方法之不能計算變數之間的相互影響程度外，其變數相互影響關係與傳統TAM2模式變數相互影響關係之主要差異為，主觀規範(X5)並未對印象(X８)造成影響，經驗(X6)會直接影響認知有用性(X1)、使用意圖(X３)；自願性(X7)亦會直接影響使用意圖(X３)；以及使用意圖(X3)會影響認知有用性(X1)。

Traditional TAM studies establish and verify the model of causal relationship between variables by factor analysis or structural equation modeling. However, some technology is highly complicated, not all respondents have thorough comprehension. Certain variables are not compatible with assumption of independence, and causal relationship cannot be analyzed accurately if mass samplings are difficult to obtain, resulting in mistaken conclusions. The study establishes TAM through the DEMTEL method, which considers the influences of inconformity between variables. Respondents may completely understand the technology, but may not adequately express it through limitations of mass sampling. Score quantification through traditional investigation asks respondents to make a choice from limited wordings in order to stress maximum attribution without considering the fuzzy thinking of humans, resulting in an imprecise summary. This study adopts Fuzzy DEMATEL to calculate the causal relationship and level of mutual effect, building on the technology acceptance model by applying the PLM system, providing administrator references to improve promotion of new technology to solve complicated and difficult problems in practice. The example of product life cycle management adopted by the Taiwan optronics manufacturing industry is used to explain the application and effect of this theory. The research found that the influence is similar to the TAM2 model based on Fuzzy DEMATEL theory. The major difference is the subjective standard (X5) did not affect the impression (X８), while the experience (X6) directly affects the purpose of use (X1) and the purpose of use (X3) which also affects useful knowledge (X１),and voluntariness (X7) directly affects the purpose of use (X3).
