近年來各國之間注重環保的聲音越來越大，政府之間開始規定法規，規定製造商必須處理它們生產出來的所被廢棄的物品。像是廢電子電機設備指令(Waste Electrical and Electronic Equipment) 和禁用有害物質條款(Restrictions on the use of certain Hazardous Substances)都會影響以代工電子產品為主要產業活動的臺灣。 在環保的主題，主要有二塊領域在探討著。一塊是設計具有環保要素的產品；另一塊是研究回收材料的技術領域。本文所研究的會針對於設計環保要素的產品上面。過去傳統只考慮到產品的生產時間以及製造成本，在本文之中，加入了產品回收之後的處理成本和時間考量。在此考量之下，原本在製造時間成本較具有競爭性的產品設計方案，也許會被其它考慮到回收階段的產品設計方案所打敗。 本文的主要架構是建構在多項式同步工程之下，在此架構之下，製造商將會有一群的產品設計方案。本文將會利用事件驅動流程圖（Event-driven process chain）來規畫產品的整個生命周期，並且利用作業成本制（Activity-based costing）來分析產品所需要的成本以及資源；接著，我們將會利用斐式圖（Petri Net）來模擬產品的整個生命週期流程，進而得之產品在各個階段的時間和成本。最後，我們會利用多屬性決策方法（TOPSIS）評估所有的產品設計方案，並且找出最適合的產品方案。 Recently, countries and society pay more and more attention to improve environment. For example, Environmentally Conscious Manufacturing and Product Recovery (ECMPRO) has become an obligation to the environment and enforced primarily by governmental regulations. RoHS (Restrictions on the use of certain Hazardous Substances) and WEEE (Waste Electrical and Electronic Equipment) are set up in Europe, and it will affect the electronic industry especially in Taiwan. Considering environment issue, there are two commonly accepted primary objectives have been gaining momentum. One is creating environment products, and the other is developing techniques for product recovery and waste management. This research focuses on creating environment products. At designing product stage, designer consider many factors to gain the lowest time and cost. In traditionally, a designer estimates forward logistics issue and this research will extend the scope that includes reverse logistic. Propose of this research is building a decision support framework. Scheme of this research is developing a Set-based concurrent engineering approach for environment product design. SBCE seeks to regions of the design space, characterize boundaries of current capabilities and discover where these boundaries can be expanded. There are two benefits of applying SBCE. One is firms could get more competitively product alternative by intensifying competition between the design teams. The other is the unselected design alternatives can keep on record to reuse for future if business condition changes. This research will accord several steps to model this decision support framework with SBCE for environment-conscious product design. We will model the process according the product life cycle, and apply the Activity-based costing to calculate the cost. Finally, we simulate this model by Petri net and evaluate by TOPSIS.
