1ERP 的演进史.ppt

1、,ERP 的演進史,ERP 演進圖,1960 MRP,MRP之前 (電腦發明前),訂貨是以所賣的商品為基準。 “預測需求”在當時是大工程，很不易達成。 事實上 “再訂購點系統” 對於管理這些採購的部分，成效還有很大的進步空間。 (True reorder point system to effectively manage those purchased parts failed miserably.),MRP shows up ! (因為: 電腦被發明了 O),電腦發明後 (1950s),隨著cpu的發明，物流管理的王道也出現了! (With the invention of the CPU

2、 an epiphany in material management occurred.) IBM位於Poughkeepsie廠的Dick Ling博士寫出了第一個物料需求軟體。 (According to Dick Ling,CFPIM,at an IBM plant in Poughkeepsie, NY, the first requirement generation software was written .),APICS,資源管理學會在1957創辦了美國生產與庫存協會 - APICS。 American Production and Inventory Control Soci

3、ety. 三個業務要項: 1.教育 2.訓練 3. 形式化(formalization) 目標: 整合兩種最關鍵的企業資源庫存及直接勞工 (inventory & direct labor),1970年代,MRP已是世界常見的技術。. 1975 Joseph Orlicky 寫了一本 ERP經典之作: “ The New Way of life in Production and Inventory Management” ！,1970 Closed-loop MRP,閉環式物料需求規劃 （Closed-loopMRP）,除了物料之外，還必須擁有足夠的產能才能達到目標。 必須定義生產路徑。 T

5、nd operations planning to the management toolbox. During this time, few computer tools were commercially available to complete these calculations. The sales and operations planning process was accomplished offline in a manual process and reviewed on a monthly basis.,The Oliver Wight ABCD Checklist (
