<p>PROBLEM TO BE SOLVED: To solve the problem that the operation rate of a line can not be increased when the line is constructed in a factory or the operation rate of manufacture and processing within a construction object range is extremely increased in a period other than the construction period to make the quality of a product not stable enough. SOLUTION: When the operation rates of respective stages are adjusted for construction such as installation and repair in a manufacture and processing field having at least one or more factories in which two or more manufacturing and processing stages having at least one or more devices are in operation, at least one of the operation rate before the start of the construction period of the construction object range, the operation rate after the completion of the construction period of the construction object range, the operation rate in the construction period of manufacture and processing stages except the construction object range, and the operation rate not in the construction period of the manufacture and processing stage except the construction object range is not varied to suppress variation in the operation rate of the processing stages except the construction object range.</p> |
