考慮風險因素下之綠色供應鏈模糊多目標整合運籌模型

本研究以綠色供應鏈整合正流鏈和逆物流鏈的概念框架為研究背景。當全球競爭日益加劇以及供應鏈變得更大和更複雜，供應鏈建模已經成為至關重要的，因為公司面臨更為複雜的全球化和較高的顧客期望。此外，綜合物流模式和環保意識也已經引起了業者和學者相當大的興趣。由於環境的不確定性，很多學者使用模糊集合理論來處理不確定需求及外部原物料的問題。再加上最近商業社會也都面臨著愈來愈多的風險，現在供應鏈在複雜且不確定的環境中，許多真實的案例涉及有關供應鏈的風險。本研究的目的是提出一個考慮風險因素的綠色供應鏈模糊多目標整合運籌模型，且當正物流鏈加逆物流鏈時的利潤最大。因此本研究根據上述的概念框架來考慮在正物流的供應鏈風險，把風險以公式加以量化，定義風險等於風險因子的發生機率乘上風險因子所對應的成本，求解多目標決策模型。最後，一個實際的單一案例，將這些數值範例所給定的數值投入則可計算出答案，此例說明可以找出一系列的參數值使這個模型的總利潤最大。因此證明本研究所提出的考慮風險因素之綠色供應鏈模糊多目標整合運籌模型是可運作的。

並列摘要

When global competition is intensifying and the supply chains are becoming greater and more complex. Supply chain modeling has become crucial as companies face more complex globalization and increasingly higher customer expectations. Also, integrated logistics model and environmental awareness have attracted considerable interest from both the practitioners and academics. Due to the uncertain environments, a body of researchers have used fuzzy set to handle uncertain demands and external raw material problems. Business communities have increasingly faced more risks recently. Now in the supply chain, many real cases are closely related to a supplier-originated risk. This research defines some supply chain risk, which will be quantified as the multiplication of corresponding probability of occurrence of the risk factors and the corresponding cost of occurrence of the risk factors. The objective of this research is to propose a fuzzy multiple objective integrated logistics model in a green supply chain considering risk factors and to discuss the maximizing profit of both manufacturing and reverse chain in a fuzzy environment. Finally, numerical example study was conducted to illustrate the results of the proposed model. The results of this example illustrate a series of parameter values to make this model the total profit maximization. Furthermore, if there is a real case, then those values from the real case can be applied to the proposed model.
