Production management information output device and production management information output method

摘要

PROBLEM TO BE SOLVED: To output effective information for shortening production TAT without reducing the shipment of semiconductor products. SOLUTION: A production progress management system calculates the processing results of respective processes, the inventory of work in process (= arrival + inventory) of respective processes, etc., as an information indicating the states of manufacturing lines. Shipment data to 'arrival + inventory' in each prescribed period (e.g. a day) in each process are plotted on a graph and displayed on a data display terminal as a graph in each process. While observing the graph plotting the shipment to the 'arrival + inventory', a production manager detects the reach of the shipment to its limit even when 'arrival + inventory' is increased, sets up an objective shipment S1 near the reach of the shipment to the limit and can limit the 'arrival + inventory' within a range capable of obtaining the objective shipment S1. For instance, the 'arrival + inventory' can be set up to '11'.
