PROBLEM TO BE SOLVED: To renew, for the next slab, the plan of the extraction order and the rolling order for a heating furnace by taking into consideration a rolling treatment of a following material during a cooling treatment of a preceding material, with changes in real operation made reflected.SOLUTION: An operation part creates planning data including an order of extraction from a heating furnace and a rolling treatment pattern on the basis of data on a to-be-treated slab (target slab) (step S2) and optimizes the plan of the order of extraction of the target slab from the heating furnace and the rolling order (step S3). When the achievement of the order of extraction of the slab from the heating furnace and the rolling treatment pattern is different from the plan, the planning data is changed so as to match the achievement of the order of extraction of the slab from the heating furnace and the rolling treatment pattern is changed (steps S6 and S2), and the plan of the order of extraction of the target slab from the heating furnace and the rolling order is optimized while meeting the restriction condition of not changing the actual achievement of the order of extraction from the heating furnace and the rolling treatment pattern. |
