摘要: | 由於科技的進步與消費者需求的改變,導致社會中大量產品快速的替換和淘汰,因此造成環境的破壞與污染。當產品在生命週期末期時,一個好的拆卸順序可以減少拆卸所花費的成本與時間,亦可使產品有效地回收再利用。然而,生成產品拆卸順序,需要產品零件之間的幾何關係與接觸資訊,而本研究是使用產品的幾何參數矩陣(Geometry Matrix)來表示產品零件之間的幾何關係與接觸資訊。本研究以SolidWorks API (Application programming interface)做二次開發,使用VBA (Visual Basic for Applications)函數編譯器開發一分析工具。此分析工具可以從使用者輸入的產品CAD檔中直接得出產品的幾何參數矩陣。本研究也設計出一個使用者介面,提供使用者輸入產品的各個零件資訊,之後自動規劃出最佳的拆卸順序,並輸出至使用者介面,以供使用者對產品拆卸順序規劃之參考。在拆卸順序規劃方面,本研究是利用雙目標最佳化的概念,考量拆卸成本效益與環境衝擊值並取得拆卸最佳停止點。 Advances in technology and changes in consumer demand, a lot of products are replaced and eliminated rapidly. Therefore, environment is destroyed and polluted by the waste products. When a product reaches its end of life, an efficient disassembly sequence can reduce the cost and time to disassemble the product and make the recycling process more effective. However, creating product disassembly sequences needs geometric relationship and contact information between parts in a product. This study uses the geometry matrix to represent geometric relationship and contact information between parts in a product. This study uses SolidWorks API and VBA functions to create an analysis tool. This analysis tool can generate geometry matrix of a product directly from the CAD files inputted by the users. This study also designs a user interface to let users to enter part information, and, then it will automatically generate an optimal disassembly sequence to the designers. In the step of disassembly sequence planning, this study uses the dual-objective optimization functions to determine the optimal stopping point based on the cost benefit and environmental impact. |
