隨著產品製程趨於複雜，產品製程由單一製造廠區逐漸被切割成多個製造廠分別負責生產的型態。因此，企業從原先單一製造廠的生產環境，漸漸演變成為一個小型供應鏈的生產型態，企業如何妥善管理與規劃企業內部的小型供應鏈來滿足最多客戶的訂單，以賺取最大的利潤，是許多企業目前迫切追尋的目標。
本研究以TFT-LCD（thin file transistor-liquid crystal display）產業鏈面板製造商為例，探討供應網路之生產規劃問題。由於該產業因製程繁瑣、冗長，主要可分成陣列（Array）、組立（Cell）與模組（Module）三大製程階段，且隨著目前液晶顯示器尺寸的市場需求日益增大，TFT-LCD製造商先後擴建多個廠區來滿足大尺寸面板的需求，而因而形成多階層多廠區的生產鏈結構；於如此複雜的網路結構下，為了能得到準確的生產計劃，需在規劃的同時考量訂單資訊、產品結構、物料供應商特性與生產鏈架構，方能有效的規劃每筆訂單於適當的期間至適當的廠區進行生產。
當供應網路問題中訂單數量增加或產品結構越複雜導致問題的複雜度不斷的增加，而使得模型需花費大量的資源或時間求解。因此本研究依據TFT-LCD生產鏈包含推式（Push based）與拉式（Pull based）供應網路結構，並應用Decompose的方法將原本供應網路區分為推式與拉式供應網路模組，透過推式與拉式供應網路資訊回饋的方式來降低兩規劃模組生產計畫的衝突。
最後，設計單一產品與多產品的情境下，分別比較「傳統規劃流程」與「拉推式供應網路規劃流程」於訂單延遲的績效表現，實驗結果顯示拉推式供應網路規劃流程於兩情境下的表現均較佳，尤其是在低產品需求預測的情況下，更能表現出拉推式供應網路規劃流程的效益。
