PRODUCTION INSTRUCTION SYSTEM AND PRODUCTION INSTRUCTION METHOD

摘要

To create production instructions in a short period of time, in the presence of a divergence between a planned production number and the number of performance generated by variations of production volume due to variations of yield with respect to production lines of electronic device products such as a hard disk and a liquid crystal display, a product ratio of input volume to a production line (product mix) is changed by calculating the average number of performance and a standard deviation in an arbitrary period from the divergence between the planned number of production and the number of performance at the present and the production performance in the past; calculating a target achievement probability to a final target from the average number of performance, the standard deviation and the production performance at present; and comparing the target achievement probability to the final target with a threshold.
