摘要
考量到資源的有限以及對環境衝擊的影響，因此產品從設計、製造、銷售、及回收最好能夠形成封閉的循環，才可降低生產成本以及減少環境衝擊。在各種方式中，產品之再製造最具有可行性。本論文提出產品再製造設計的研究架構主要包含了兩個部分，首先以類神經網路之倒傳遞網路來分析產品在使用之後的處理策略，其中包含了再使用、維修、再製造、材料分類回收、材料直接回收、與廢棄。第二部分則是以產品模組化的方式，在提昇產品再製造性的原則之下對於產品內之子模組作一規劃。
類神經網路具有使用簡便以及適合非線性問題之優點，在此以產品壽命終了之設計建議(End-of-Life Design Advisor)於產品處理策略之分析理論，來做為類神經網路架構建立之依據以決定適當之處理策略，並以自我組織映射網路來分析各種處理策略間之關連性。由此方式來快速模擬ELDA之分析模式，以提供使用者在相關領域之研究上一個較為簡單且易於操作之方法。
模組化在產品的設計過程上為相當重要之考量，特別是當產品具有升級的需求時。模組化一般是以產品的功能來做區分，為了能夠提昇產品再製造的可行性，因此對於功能模組下之子模組以材料、壽命、以及升級之考量來對子模組作一規劃，達到減少元件數量並提昇產品再製造性之目的。並提供設計者在相關設計考量上之原則及建議。

Abstract
Concerning the limits of natural resource and the effect on environmental impact, products had better consider the whole life cycle from the design, manufacture, sale, use and recycle in order to reduce the cost of products and reduce impact in the environment. In all kinds of ways, the remanufacture of the products is the most practicable strategy to arrive above goals. The main structure of this thesis includes two parts. First, it analyzes the end of life strategies that includes the reuse, service, remanufacture, recycle with disassembly, recycle without disassembly and disposal of products by the back propagation neural network. Another part is planning sub-modular of products with the way of product modularity to enhance the remanufactureability.
Neural network has the advantages of easily to use and feasible to non-linear problems with learning capability. The theory of End-of-Life Design Advisor (ELDA) is selected as the basic structure of back-propagation neural network to determine the useful strategy. Furthermore, self organize map neural network was selected to analyze the relation between each strategies. Hence, the trained neural networks can simulate the analysis mode of ELDA rapidly and offer the designer with an easy operation method in the relative research domain.
Product modularity plays a quite important role in designing procedure, especially when the products have to be up-graded. General speaking, product modularity is divided from the functions. In order to enhance the possibilities of remanufacture and decrease the quantity of parts, we divide the sub-modular of products based on the point of view of material, life and up-grade. Finally, this thesis provides the designer the design principles and suggestions in product remanufacture design tasks.
