Implementing optimization program for AS/RS picking scheduling in support of production lines

[[abstract]]自動倉儲系統(AS/RS)能大量減少操作時間、儲存成本，及人力資源的浪費，並可充分利用儲存空間被廣泛的應用及定位在支援現場的物料儲存。自動倉儲不僅影響物料搬運效率，在生產線的作業效率都受其深遠的影響，一般而言，自動倉儲系統是相當昂貴的，為了獲得更佳的生產力，自動倉儲系統物料揀貨排程變的極為重要，也就是說，必須設計自動倉儲系統的方法是很重要的。 本研究主要考量自動倉儲支援組裝工作單元供應其物料需求，建立考慮組裝線的物料需求，以及自動倉儲對物料供貨的能力，並建立兩階段的最佳化模式，第一階段為取貨端訂單分批次；第二階段為組裝端作業，並利用 LINGO 數學規劃套裝軟體運算求解。利用兩階段的數學模型找出相似程度最大的訂單批次組合。[[abstract]]In modern production and distribution systems the automated storage/retrieval systems (AS/RS) high-storage level systems that reduce labor cost required floor space and error rate while increasing product availability The AS/RS system not only has a profound impact on efficiency of material handling but also on operational efficiency of product line Generally AS/RS were equipped at great expense; however with the aim of reaching higher productivity growth the application of AS/RS should be given first priority which is to say that to design AS/RS system evaluation is inevitable We consider AS/RS in the support of an assembly line having multiple cells For the coordination between the assembly line and the AS/RS two-stage integer programming models are considered and using LINGO mathematical optimization software to construct the IP model Our goal is to find optimal orders combination
