Managing apparatus and managing system

A managing system, comprising:

• a plurality of managing apparatuses for factory equipment, the plurality of apparatuses being connected with each other via a network,
• each managing apparatus of the plurality of managing apparatuses being used in a manufacturing site in which a first machine tool for high-precision machining and at least one other machine are in operation, and used for managing an operation of the other machine, the each managing apparatus comprising a processor configured to:
• collect quality information on a workpiece having been machined by the first machine tool and operational information on the other machine,
• perform an analysis for determining correlation between the quality information on a workpiece having been machined by the first machine tool and a change in the operational information on the other machine,
• make an operation plan, based on the determined correlation, for imposing a restriction on an operation of the other machine to reduce a change in an environmental temperature of the first machine tool during high-precision machining performed by the first machine tool,
• provide an operation instruction to the other machine based on the made operation plan, and
• share an analytical result obtained by the processor with other managing apparatuses among the plurality of managing apparatuses.
