在新產品開發專案中,產品設計進程必須在眾多可資利用的資源與資訊中,憑藉各類分析工具理出具效益的解答方案,本研究結合模糊計劃評核術和層級分析法探討企業內部的設計部門策略對其設計師的設計思維脈絡之影響。其做法為應用層級分析法(AHP法)的權重法則,建構模糊計劃評核術的網路結構,然後進一步應用模糊計劃評核術呈現個案設計師所認知最具影響性的模糊要徑,配合個案測後訪談歸納其認知原因與意見。結果發現其深受(1)主管、客戶所採用的具體重視手法。(2)設計師們對部門策略的具體指標性手法範疇印象深刻。(3)基於專業信賴度與設計默契的設計自主養成下,偏重於自身的經驗法則與實務的設計型態。(4)設計師們之彼此設計默契與設計資訊分享型態所促進之共識性看法。(5)在相異與雷同錯雜的產品定位訴求模式中,間接影響設計師之務實的設計型態的認知共識看法。(6)公司的產品設計慣例性型態觀念根深蒂固。等六大項因素所影響。
In the project of new product development, the product design process must be in the numerous resource and information that can be utilized, according to making use of all kinds of analysis tools to pay attention to the answer scheme which provide benefit, this research combines the Fuzzy PERT and the AHP approach and probes into the tactics of design department at enterprises inside to influence designers' context of design thinking. Its course is built the network structure of Fuzzy PERT by applying the weight rule of Analytic Hierarchy Process approach (AHP), then further use the Fuzzy PERT approach to present designer's cognitive most influential the Fuzzy-Path and sum up designer's cognitive reason and suggestion in interview after cooperating with the examined cases. The result with the cases examined had found more influence on the factors of six items (1) Concrete attention approaches which executive, customer adopted. (2) The impression of the concrete index approaches category of the department’s tactics to the designers is influentially deep. (3) Base on the trust of the professional specialty and the tacit design that are formed with independence from design category, it overweight one's own experience rule and design type attitude of the pragmatism. (4) The designers' design tacit understanding and design information sharing type attitude of each other would promote the common understanding view. (5) To Make a reservation and demand in the mixed products mold with heterology and duplicate, influence the cognitive common understanding view of the designer's practical design type attitude indirectly. (6) The notion of customary pattern to the product design of the company is deeply rooted.
