METHOD FOR DESIGNING PRODUCTION LINE

摘要

PROBLEM TO BE SOLVED: To reduce production costs by optimizing the number of devices and the number of workers even in a production line in which one worker operates a plurality of devices. SOLUTION: A processing capacity parameter is defined for each device variety, in which a device for integrating and processing an (n) number of lots is set as (n) and a device for processing by dividing one lot into (m) batches is set as 1/m. A value obtained by dividing the actual reaching rate of objects to each device group with a processing capacity parameter is set as a reaching rate to its device group (step 106), and the number of necessary devices is calculated for each variety (step 108). Workers are grouped according to the levels skills. The sum total of reaching rates to all the devices operated by each group of workers is set as a reaching rate to the group (step 103) and the number of necessary workers in the group is calculated (step 105).
