<p><P>PROBLEM TO BE SOLVED: To provide an operation system of a factory which can be stably operated while saving energy by preventing the unexpected decrease of a pressure for a factory having a plurality of production facilities consuming compressed air. <P>SOLUTION: An operation system 100 of a factory is provided with: a database 113 for storing the time series data of the flow rate consumption of each production facility and the tact time of each production facility (a); a facility operation schedule determination part 114 for specifying the maximum operation valid section whose total flow rate consumption is equal to or less than a threshold and the first and last tact start time of each production facility in the maximum operation valid period from the simulation result of the time series change of the total flow rate consumption by using the time series data of the flow rate consumption of each production facility and the tact time of each production facility (b); and a facility operation control part 115 for repeatedly starting the operation of any of production facilities 105 to 107 in the first task start time, and for stopping the operation of any of the production facilities in the last tact start time in the cycle of the maximum operation valid section. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
