PROBLEM TO BE SOLVED: To improve the adherence ratio of indicated date of delivery by changing priority order in each process on the basis of relative ahead/delay degree and the importance of each products in relation to the appointed concluding time. SOLUTION: A computing unit 13 for computing ahead/delay time (d), a computing unit 14 for computing the standard working time D and a (d)/D computing unit 15 compute the relative ahead/delay degree (d)/D. A discrimination whether plural products compete with each other or not is done in each process. In the case where plural products compete with each other in the same process, priority order for specifying working order of the plural products is decided by a priority order deciding unit 16. After the priority order is decided, work is delayed from the working plan time of the process on the basis of a coefficient of importance previously given to each product competing with each other, and priority order of the products having high degree of importance regulated by the coefficient of importance is changed by a priority order changing unit 17. |
