Method for allocating steel for ladle, method for operating steelmaking factory, and apparatus for allocating steel for ladle

摘要

Based on the steelmaking plan data including information on the steelmaking start time and casting end time for each steelmaking charge, and information on the next available time for each molten steel pan (step S1), the calculation unit (step S1) A plurality of plans for allocating molten steel pans are created by satisfying the constraint conditions excluding the predetermined constraint conditions (step S2), and a plan satisfying the predetermined constraint conditions is extracted from the created plans (step S3). ), For the extracted plan, a predetermined evaluation index including an evaluation index for the maintenance workload of the operator is calculated (step S4), and the extracted plan is presented in association with the calculated predetermined evaluation index (step S5).
