<p>PROBLEM TO BE SOLVED: To provide production management method and apparatus which inexpensively and effectively make the most of space in a production line and realize first-in first-out control of products to be processed. SOLUTION: The apparatus comprises a feed speed manager for managing a production progress degree of a semiconductor wafer 1, a personal computer 3 connected to the progress degree manager for displaying thereon production progress degree information stored in the progress degree manager, a storage shelf 6 having an accommodation case 4 having the semiconductor wafer 1 housed therein and having a sequencer 5 connected to the personal computer 3, and a bar code reader 8 for inputting a lot number 7 of the semiconductor wafer 1 to the personal computer 3. Installed in the storage shelf 6 are a sensor 9 for detecting presence or absence of the accommodation case 4 and a display LED 10 indicative of detection information of the sensor 9, so that the sequencer 5 controls the sensor 9 and display LED 10 to thereby control input and output of the accommodation case 4.</p> |
