HEATING-FURNACE-EXTRACTION ORDER GENERATION DEVICE, HEATING-FURNACE-EXTRACTION ORDER GENERATION METHOD, AND STEEL PLATE PRODUCTION METHOD

摘要

A pattern generation unit (103) generates a plurality of process patterns incorporating each process in a transit process for each rolling material and occupancy time of equipment used in the processes. An optimal heating-furnace-extraction order generation unit (104) generates modes incorporating the process patterns selected one at a time for each process in the transit process for each rolling material, selects, on the basis of equipment constraint conditions and constraint conditions for the quality of rolling-material manufactured articles, a rolling material mode combination having the shortest total rolling time, and generates, on the basis of the selected rolling material mode combination, a rolling schedule and a heating-furnace extraction order for the rolling material. As a result, steel-plate production efficiency can be improved while improving steel-plate rolling efficiency and satisfying manufactured article quality conditions.
