PURPOSE:To improve producing efficiency by preventing the increase of the number of works in each process, thereby shortening a period required for production in the scheduling of a work start (input of products to the process) instruction in the plural processes. CONSTITUTION:A work start date and end date in a first process and the work start date in the second process are searched (step X1-X4), and the number of waiting days until the work start date in a second process obtained by subtracting the work end date in the first process from the work start date in the second process is compared with the preliminarily set number of permitted waiting days (step X5 and X6). When the number of waiting days is beyond the number of permitted waiting days, the work start date in the first process is delayed only by the difference (step X7). When the number of waiting days is less than the number of permitted waiting days, the work end date in the second process is calculated (step X8). Afterwards, the same operation is repeated in the following process. |
