PROBLEM TO BE SOLVED: To provide a scheduling drafting method that reduces power expenses and can flexibly deal with even changes of production conditions or the like. SOLUTION: This scheduling drafting method defines each of a processing time by the equipment related to production, the amount of used power, the number of necessary workers, a time that can start processing the next process earliest, and a time that can start processing the next process latest by a linear equation that takes the production amount as a variable, and divides the processing into plural small processing, defines the processing time of the equipment, the amount of used power, and the number of necessary workers by the linear equation that takes the production amount as the variable and makes a production unit as production equipment information obtained by giving these linear equations the production amount of a plan object production as a unit of a plan drafting when the amount of used power and the number of necessary workers are different from time to time in a single processing. Also, each production unit is preferentially allocated to a time band during which charge for power amount is cheaper in the decreasing order to the amount of used power. |
