METHOD FOR MANUFACTURING STEEL SHEET

PROBLEM TO BE SOLVED: To provide a method of manufacturing a steel sheet, wherein production efficiency can be improved. SOLUTION: This method is a manufacturing method of the steel sheet which is used on a manufacturing line provided with a rolling line 1, a finishing line and a cooling bed group consisting of a first cooling bed and a second cooling bed which are arranged between them. The manufacturing method of the steel sheet is provided with: a temporarily deciding stage where a cooling bed on which a plurality of the steel sheets are charged is temporarily decided in accordance with the shape of the plurality of the steel sheets which are conveyed in order on the rolling line 1; a first predicting stage where the idle time T1 which can be generated on the rolling line 1 when the plurality of the steel sheets 5a, 5x, 5b are charged to the cooling bed; a temporary decision changing stage where the temporary decision after changing is performed by changing the temporary decision of the cooling bed when T1>0; and an adopting stage where the idle time which can be generated on the rolling line 1 is predicted when the plurality of the steel sheets are charged on the cooling bed according to the temporary decision after changing and either the temporary decision or the temporary decision after changing is adopted as the normal decision after comparing with T1.
