模糊多階層多目標供應鏈規劃-以紡織業為例

Abstract

在面對全球化競爭的壓力下，強化供應鏈的管理能力已成為產業提昇本身競爭優勢的一種趨勢。過去的供應鏈管理多以單一目標、同一層面作規劃，然供應鏈體系實為上中下游階層關係，具有上下交互影響之特性，故實際狀況需以多階層多目標方式考量之；據此，本研究建構一多階層多目標供應鏈模式，及研擬一套互動式多階層規劃法用以求解此一供應鏈模式，並以國內某一紡織業供應鏈體系為實證對象，研究結果顯示本研究之互動式多階層規劃法可使各個廠商在所有利潤目標及產能控制目標皆可接受(滿意)下，作出最佳的生產、配銷及存貨決策；此外，本研究以傳統的模糊多目標規劃法與互動式多階層規劃法作比較，首先界定兩者間行為模式之差異，其次，根據兩種求解方式所規劃之結果分析其優劣，由其個別的規劃內容顯示，在比較之下本研究之互動式多階層規劃法較優於模糊多目標規劃法。因此，本研究之多階層多目標供應鏈模式及互動式多階層規劃法兼具可行性及有效性，期望能運用此一模式及方法提供業者在營運與管理策略之參考，以提昇其全球化的競爭能力。

Under the pressure of confronting the globalized competition, it has formed a tendency of strengthening supply chain management ability for industries to enhance themselves competition advantage. In the past, most supply chain management programming researches were focused on single objective, single level, but actually, the supply chain system have upper-middle-lower stream relations and interactive properties between all members, so we have to put the multi-level multi-objective ideas in consideration in real word situation. Therefore, in this study we construct a multi-level multi-objective supply chain model, and design an interactive multi-level programming method for solving the model. In order to demonstrate our model and method, we apply them to a domestic textile industry, and after real case study analysis, we find that: applying the interactive multi-level programming method we can obtain the optimal production, distribution, and inventory decisions under all profit objectives and product quantity control objectives are accepted (satisfied). In addition, this study compared the interactive multi-level programming method with traditional fuzzy multi-objective programming method, at first, to define the difference of behavior model between the two methods, second, to analyze their superiority or inferiority from their programming results, the results revealed that: the interactive multi-level programming method is superior to traditional fuzzy multi-objective programming method by comparison. As analyses aforementioned, the multi-level multi-objective supply chain model and interactive multi-level programming method are practicable and effective simultaneously, they can be manipulated to assist decision makers in operating and managing to enhance their globalized competition capability.
