  • Patent number: 10175746
    Abstract: Provided are a power consumption control system and method that clarify the timing for carrying out each of a plurality of processes and thereby facilitate standby power control and the leveling of power consumption. To this end, PERT analysis is performed on the basis of process information that relates to a production line, process flexibility analysis is performed on the basis of the PERT analysis, process arrangement combinations and the total number of process arrangement combinations are determined on the basis of the process flexibility analysis, distributions of the total number of process arrangement combinations are determined for the process arrangement combinations, the process arrangement combination having the smallest distribution is selected from among the distributions, the processes are rearranged, and the progression of the processes is controlled on the basis of the rearranged processes.
    Type: Grant

  • Patent number: 8866420
    Abstract: Disclosed is an electric power consumption control system for a factory where a plurality of machine tools (Mi, Mp1, Mp2) are installed. A machine tool (Mi) is provided with a control device (10) whereby either the rotational acceleration/deceleration (Pi) for the motor for the machine tool and/or the rotational speed (Si) thereof is controlled on the basis of information regarding electric power consumption (Wt) in the factory so that electric power consumption will not exceed a specified value (We). This electric power consumption control system is also provided with electric power detection instruments (11, 12, 13) and an electric power monitoring instrument (20) which measure the electric power consumption of all the machine tools installed in the factory, thereby obtaining the electric power consumption of the factory, and provide information regarding the electric power consumption to the control device of the machine tool equipped with the control device.
