摘要

在產品設計過程中，配置設計為統整步驟，將先前設計的元件及條件組合。隨著產品功能複雜化，元件間的設計衝突也隨之增加。如何系統化地協調元件間的衝突，為配置設計方法的日趨重要的一部分。以往的設計方法大多僅從元件參數或僅以元件為單位討論，本研究從元件間關係著手，討論兼顧元件、元件關係和不同設計環境下的設計參考。
本研究以公理化理論設計模型及以環境為基礎的設計做為理論基礎，建立一套適用於配置設計的模型。模型包含環境定義、衝突辨識及概念產生三部分。在環境定義中，確認設計中環境與產品的邊界，以及環境、產品元件及元件間的特性；在衝突辨識中，整理元件間及元件與環境間的關係屬性、方向；最後經過協商排除衝突並產生設計概念。
本研究並提出元件重要性由每條相關的關係重要性所組成，並將關係重要性和元件重要性做為產品衝突發生時的協商依據。關係重要性的評估由潛在影響力和直接影響力構成。將設計模型在環境評估時輔以原子理論，以每兩元件間的接觸關係找出潛在影響力；潛在影響力在衝突辨識時搭配設計師評估的直接影響力，套入語意式模糊模型得到關係重要性和元件重要性，做為配置設計的協商指標，協助產生新的設計概念。其中元件重要性可依照設計屬性提供不同方向的設計參考。
最後，將設計方法應用在叉車系統的配置衝突協商以及控制器組件的重新配置，分別以關係重要性和元件重要性做為在配置設計過程中的協商指標。協商後設計結果成功達到設計需求，包含簡化結構和訊號傳遞過程，並依協商結果產生新的配置設計。

In the product design process, the design configuration step integrates objects and constraints that are defined in the early design stage. With increasing complexity, conflicts between design objects increase. As a result, research concerning techniques for resolving conflicts between design components is becoming more important. Most prior design methods only focus on design constraints. In this study, the relationships between design objects and different design environments are considered to produce better product design configurations.
In this study, Zeng's axiomatic theories of design modeling and environment-based design problem formulation are used as a theoretical foundation to create a model for product configuration design. Creating the model consists of three steps：environment analysis, conflict identification, and concept generation. Environment analysis consists of determining the boundary of the design environment, characteristics of the environment, the design objects, and the relationships between the objects. Conflict identification involves organizing and examining relationships between objects and between the objects and the environment, to find conflicts. Finally, concept generation consists of completing trade-off analyses to eliminate conflicts and generate new design concepts.
In addition, this study introduces the concepts of object and object relationship importance measures. Object importance is defined as the sum of all object relationship importance measures between the object and all other objects. Object relationship importance measures are determined based upon potential and direct impacts. Potential impacts that relate to contact relationships between objects are evaluated using atomic theory. Direct impacts that relate to the product are evaluated by designers. Potential and direct impacts are incorporated into a Mamdani fuzzy model to determine object relationship importance measures. The resulting object and object relationship importance measures are used to resolve conflicts during configuration design.
A forklift system and a controller assembly are used as case studies to examine the object relationship importance measures that impact trade-off analyses. By resolving conflicts, the method successfully meets design requirements and creates new design configurations.
