PURPOSE:To reduce a time loss at the time of executing a scheduling once more by deciding a schedule objective date of a month when the schedule is executed by a simulation based on the information of an operational information data base by a periodic simulation means. CONSTITUTION:The calendar of the month when the schedule is attained is prepared by a monthly operating calendar preparing means 6. A period simulation means 7 decides the schedule objective date at each job by referring to the calendar prepared by the preparing means 6, based on the period of the job executable condition and the classification data of the calendar of an operational information managing data base 3. At that time, the simulation means 7 removes the job in conflict with the designation of the operational starting date, non-executable date, exclusive job of the job executable condition, from the scheduling at that date. Thus, the storage of the calculation of the scheduling time, and the scheduling result in a schedule data base can be omitted. |
