模組化產品設計─以自行車產品設計為例
Product design with modules - an example of modular bicycle product design
摘要
模組化產品設計旨在發展一個實體可分離和組合之快速發展的產品，以利於裝配、服務、重新使用、回收等產品生命週期目標。本文主要在發展以知識推理架構為基礎的模組化產品設計系統，本文首先探討模組化產品設計於面對顧客需求與產品設計之間的關聯，然後嘗試將顧客需求與產品設計的關係應用專家推理系統建立起關聯知識庫，透過轉換機制的運作建立快速解決顧客需求與產品設計的問題。 本文應用專家系統工具Protégé 3.3.1來建立專家知識庫，並以自行車設計上顧客需求之產品設計上的問題為例，將自行車需求與設計的轉換機制加入至知識庫中，並使用專家系統發展程式語言JESS (Java Expert System Shell)為推理基礎，以法則推理為基礎呈現領域專家問題求解的方法，推理出滿足顧客需求之模組化零件選擇和建議出模組化零件之可行的裝配順序，最後將選用之零件以CATIA作出裝配順序之動畫範例，使客戶可以參考裝配之實體，讓顧客選擇購買更為方便。 總之，以知識推理為基礎之模組化產品設計具有滿足顧客之多樣性、互換性、相容性等特性，以及能夠縮短產品設計時間，仍然保有高品質、低成本的優點，達到為顧客而設計之目標。

Modular product design aims to develop a product architecture consisting of physically detachable components for rapid product development, ease to assembly, services, reuse, recycling and other product life cycle objectives. A product design with modules is one in which the input and output relationships between components, that is, the component interfaces, in a product have been fully specified and standardized. In this paper, the knowledge-based architecture for modular product design is suggested, which discovers and shares the product knowledge and design rules to increase the effectiveness/efficiency of the product design with modules. This solution approach involves modeling modular products knowledge, modular components selection, and feasible assembly sequence of modular product. In modular products knowledge model, an object-oriented approach is introduced to capture the knowledge of modular product. In components selection and feasible assembly sequence of modular product, a reasoning mechanism is fabricated based on JESS. Last, a particular case of bicycle design is studied through the use of this knowledge based prototype system to prove the effectiveness/efficiency of the product design with modules. However, a knowledge-based system of product design with modules is also implemented to provide adapted design rules and share design knowledge in distributed environment. It will greatly enhance the competitive capability of companies trying to reduce the engineering design change.
