Management system and management device for a plurality of industrial machines supplied with power from a power supply facility

A management system, comprising:

• a plurality of management devices connected to each other via a network, wherein
• each management device among the plurality of management devices is for a plurality of industrial machines supplied with power from a power supply facility, and comprises:
• a processor configured to
• collect data (i) related to power consumption supplied to the plurality of industrial machines from at least the power supply facility and (ii) obtained based on a detection value detected by a sensor, and
• create power consumption data indicating information related to the power consumption supplied to the plurality of industrial machines during a predetermined time based on the collected data;
• and
• a learning model storage for storing a learning model associating a value of a behavior of allocating a predetermined total suspension time to the plurality of industrial machines with a state of power consumption by the plurality of industrial machines, wherein
• the processor is further configured to
• determine a behavior of allocating the predetermined total suspension time to the plurality of industrial machines with respect to a current state of power consumption by the plurality of industrial machines using the learning model stored in the learning model storage based on the created power consumption data,
• allocate the total suspension time to the plurality of industrial machines based on the determined behavior, and
• decide the suspension time for each industrial machine to suspend an operation after a series of operations,
• the processor is further configured to
• collect a suspension time after a series of operations of the industrial machine,
• create the power consumption data, suspension time allocation data, and power consumption determination data, and
• generate a learning model,
• the suspension time allocation data indicate allocation of the predetermined total suspension time to the plurality of industrial machines after a state of power consumption indicated by the power consumption data is observed,
• the power consumption determination data indicates a determination result for power consumption within a predetermined time by the plurality of industrial machines in the case where the total suspension time indicated by the power consumption data is allocated after the power consumption indicated by the power consumption data is observed,
• the learning model associates states of power consumption by the plurality of industrial machines with allocation behavior of the predetermined total suspension time to the plurality of industrial machines based on the power consumption data, the suspension time allocation data, and the power consumption determination data, and
• a learning result by the processor of one of the plurality of management devices is allowed to be shared among the plurality of management devices.
