Abstract:
A target generation system for a production line, wherein a number of lots of workpieces are moved through a series of fabrication stages during processing, comprising:means for setting for each lot an initial delivery date (REQ_DATE), wherein the REQ_DATE is defined by a purchase order; means for monitoring the processing of each lot while passing through the stages, comprising: means for calculating days remaining (DR) by subtracting a present date (TODAY) from the initial delivery date (REQ_DATEâˆ’TODAY) for each lot; means for calculating remaining stages (Sg) for each lot to reach a last processing stage by subtracting a number of an instant stage from a number of the last processing stage; and means for dividing the remaining stages by the remaining days (Sg/DR) to derive penetration stages per day required for each lot; and means for using the derived penetration stages to target for a movement of the lots through each remaining stage to meet the REQ_DATE defined by the purchase order.
