PURPOSE:To reduce the burden to succeeding scheduling and to prevent unnecessary schedule change by coupling a proper number of lots to one job. CONSTITUTION:In steps S1 to S2, the appointed date of delivery and the number of products in each lot are assigned as the request quantity in each certain time unit, and the production capability is assigned on the same time base. In a step S3, the time base is traced to detect the assignment time of the request quantity, and it is set as the calculation start time. In a step S4, the time base is traced to calculate the difference between the request quantity and the cumulative value of the production capability. In a step S5, the time when this difference is reduced to a negative prescribed value or smaller is detected, and calculation is temporarily terminated at this time. In a step S6, plural lots included from the calculation start time to the end time are coupled to one job. |
