Production scheduling system

摘要

The present invention provides a master production scheduling system in which overstocked parts are disposed of with minimum loss. The master production scheduling system refers to data stored in a data storage apparatus 101 and performs the following processing: an MRP explosion apparatus 115 explodes a product listed in a production plan into gross requirements; a retired parts estimating section 116 specifies overstocked parts based on the explosion results; a producible product quantity calculating section 117 calculates a producible product quantity for a retired model which can be produced using the overstocked parts; an additional parts order estimating section 118 calculates the value of an additional parts order (which is an amount of money to be paid for parts to be additionally ordered) for each quantity of retired model products to be produced; and a retired parts disposal section 120 drafts a production plan for the retired model in which the value of the additional parts order is minimized based on the producible product quantity and the value of the additional parts order.
