以系統動力學方法建構動態設計決策模式

Constructing the Dynamic Design Decision Model in Light of the System Dynamics Method

受到物聯網、雲端運用、大數據等新資訊科技的影響，產品設計公司的管理者在進行決策時，不僅要考慮設計、製造及行銷領域因素的影響變化，並且需要考慮新資訊科技領域因素對設計決策的影響；其中任何一個領域因素的影響程度都會對其他因素產生極大影響，形成牽一髮而動全身之情勢，倘若決策失誤，對產品設計公司的發展極為不利。因此，本研究之目的為建構即時反應因素之間影響程度的模式，用模式計算的數據結果，來協助產品設計公司進行設計決策。透過個案公司實際驗證的結果顯示，動態設計決策模式可呈現達成決策目標之重點因素，有助於提高管理者的決策效率，並為產品設計公司提出具體建議和對策。

Influenced by new information technologies such as the Internet of Things, cloud application and big data, the manager of product design companies should consider not only the factors that influence the design, manufacturing and marketing fields, but also the factors of the new information technology that has an impact on the design decisions. The influence degree of any factor has a great impact on each other, forming a situation that affects the body as a whole, and the wrong decision will be extremely unfavorable. Therefore, the study aims to construct a dynamic design decision model (3DM) which assesses the degree of being influenced by real-time response factors and assists in design decision-makings by employing the data from the model. The actual verification of the case company shows that the dynamic design decision-making model can present the key factors to achieve the decision-making objectives, helping improve the decision-making efficiency by putting forward specific suggestions and countermeasures for product design companies.
