由於環保意識抬頭,在相同功能與條件之下,環境衝擊越低的綠色環保產品越受消費者的青睞,所以許多企業紛紛自動自發的進行產品環境衝擊評估之認證,以提升自己的企業品牌價值,但其評估程序往往於產品設計至量產後,才執行相關產品的環境衝擊評估,若發現所設計之新產品對於環境衝擊程度過高,亦開始針對不良之高排碳與高成本之零組件/原物料進行事後改善,此舉不僅導致決策困難,同時造成產品開發之成本增加,以及產品開發時效性之延宕。因此本研究將彙整供應商蒐集而來之數據或利用先前已盤查過之資訊,求出新產品碳足跡與成本之極值解,再利用多目標之逐步法求解,同時考慮碳足跡與成本皆達到決策者所滿意解即低排碳及低成本之最佳零組件供應商之選擇,期望在設計端時就提供設計者一個產品環境衝擊與成本的評估方法,來篩選造成環境衝擊較大與成本較大之零組件供應商,讓設計者可以透過計算後之結果,來針對新產品之零組件結構做設計。
Due to rising awareness of environmental protection, more and more consumers paid their attention to the lower environmental impact product development under the same features and conditions. Many companies begin to perform the environmental impact assessment and get the certification for their products in order to enhance their brand value. However, this environmental assessment process is generally implemented only when the products are designed and mass produced. It is too late for the designers to change their product design when they found the product may have higher environmental impacts. The reason is that it will cost a lot of efforts and costs to perform the change. In this research, the products’ environmental impacts are provided and analyzed during the design stage based on the previous certified products. In order to solve the confiscation of carbon emission and cost problems, a multi-objective decision making method, step method. Finally, a case study is applied for the demonstration of the results.
