Attorney, Agent or FirmInternational ClassG06F 019/00AbstractA method/system for performing dynamic re-scheduling of priorities of work-in-process in a fabrication plant for manufacturing of a product is provided. It reads a key stage report for the work-in-process and a master production schedule for the work-in-process from stored data. It generates a master production schedule report from the key stage report and the master production schedule following only Due_Date data for the work-in-process, and generates a work-in-process distribution matrix for integrating the master production schedule report with work-in-process quantity data within a deliverable cycle time; allocates selected lots from the work-in-process distribution matrix using a snake pattern method to allocate the selected lots from the matrix, and changes the due date for the selected lots of the work-in-process selected by the snake pattern method. It generates a final re-scheduling table for the work-in-process including the selected lots.Other References
