Purpose&strategy,Modeling integrated dispatch rule in dispatching system in order to systematized.,Purpose:,Achieve monthly/quarterly production plan,create the maximum revenue,reduce production cycle

同,沒有一定的模式,現場派工訊息直接傳遞,現場派工有一定的模式,產品交期,人工處理更改產品交期,系統自動調整交期,機台負荷,機台負荷平均化不易全,盤掌握,系統自動調整機台負荷,平均化,Back,Basic Dispatch Strategy,-1/13,Example:Lot priority for priority class,EQP A,Lot2,Lot1,Ready,Lot3,Super
