由於經濟活動增加的規模效應與大量且頻繁的運輸工具所產生的廢氣,使全球暖化的問題日益嚴重,其中又以工業與運輸部門排放溫室氣體為最多。為了有效的控制溫室氣體的排放,減緩氣候的變遷,京都議定書規定各國溫室氣體減量的責任。傳統的供應鏈網絡以經濟考量為主要目標,但是二氧化碳的與日俱增,環境的永續性,已經成為不容忽視的目標。因此本研究不僅考慮到成本,也兼顧到環境考量,設計一多目標最佳化模式,考量顧客多期需求之下,針對供應商選擇、工廠選擇、工廠生產批量,以及零組件與產品運輸量的多運輸模式之供應鏈網絡模型,解決多廠區生產資源分配與生產規劃問題。本研究透過正規化限制法,求解多目標問題。最後透過數值範例分析,提出管理層面意含。冀望本研究之模型,可供企業在全球佈局時參考,同時兼顧環境與經濟的發展。
Global warming has become an intensified issue because of increasing economic activities and the abundance of emission the industry department and transportation make. Kyoto Protocol provides for the responsibility of countries to reduce greenhouse gases, in order to effectively control greenhouse gas emissions and mitigate climate change. In the past, the objective of traditional supply chain was economic consideration. However, the increased carbon dioxide has led to the environmental sustainability becoming another objective, which cannot be ignored. Therefore, this research considers not only the cost but also environment protection to design a multi-objective optimization model. With multi-period customer demands, the model can solve a multi-plant resource allocation and production planning problem focusing the decisions on the suppliers’ selection, facilities selection, lot-size, transportation modes selection, and how to distribute materials and commodities of a green supply network. This research applies the normalized normal constraint method to solve the concerned multi-objective problem. Through numerical analyses, some managerial insights are concluded at the end. The proposed model, which simultaneously considers the environmental and economic developments, is expected to be a reference for the enterprises with global allocation.
