基於成本效益分析的產品拆卸序列規劃

Abstract

由於環保意識高漲，綠色設計成為產品開發中重要的一部分。拆卸規劃為綠色設計中一項關鍵的因素，拆卸規劃用於增加零件的再使用、再製造、以及回收的比率。然而，大部分產品仍以手動的方式進行拆卸，因此，產品進行拆卸時需付出較昂貴的成本，而拆卸規劃正是用於妥善規劃拆卸過程並減少成本。本研究結合拆卸規劃以及成本效益分析，並規劃最少成本的拆卸以讓零件進行再使用、再製造、以及回收等產品生命週期末期(End-of-Life, EOL)之處理方式。而本研究進行之方法包含使用者介面，使用者依照產品輸入資訊於使用者介面後，介面利用產品資訊，規劃最佳的產品拆卸序列。本研究利用雙目標最佳化之概念規劃拆卸最佳停止點，在環境衝擊與拆卸利潤中取得最佳的平衡。

Due to growing concern for the environment protection, green design is becoming an important part of product development. Disassembly planning is a key element of green design. Disassembly planning is used to increase component reuse, remanufacturing, and recycling. In addition, most products are still disassembled manually. As a result, disassembly is very expensive. Disassembly planning is used to reduce disassembly costs. This thesis combines disassembly planning and cost-benefit analysis to create minimum-cost disassembly plans for component reuse, remanufacturing, and recycling. The method has a user interface. Users can input product data. The method uses the product data to find an optimal product disassembly sequence. The method uses a dual-objective optimization function to determine the optimal stopping point for removing components from a product to achieve an optimal balance between environmental impacts and financial benefits.
