Target generation system based on unlimited capacity allocation

摘要

A method and system for production line target generation based on unlimited capacity allocation utilizing an algorithm that begins with setting the required delivery date (REQ_DATE) from the customer's purchase order and using the REQ_DATE to define other related requirements by backtracking the production line requirements to determine how many stages need to be passed before delivery, and to decide where and how to setup and arrange the production equipment, in order to complete and deliver the ordered goods on time. Particularly, the processing of each lot is monitored while passing through the processing stages by: calculating the days remaining, DR, by subtracting the present date from the initial delivery date, REQ_DATE-TODAY, for each lot; calculating the processing stages remaining for each lot to reach the last processing stage, to determine the remaining stages, Sg=last processing stage's number-the instant stage number; and dividing the remaining stages by the remaining days, Sg/DR, to derive the penetration stages per day required for each lot; and then, using the derived penetration stages to target for the movement of the lots through each remaining stage to achieve the production goal in a timely manner.
