Abstract:
1. A process control system including a processor, comprising: a process state detection unit that detects activation of a process in a computer and determines whether the process is a previously determined one of control-target processes; a comparison unit that calculates a prediction value of the CPU usage rate of the entire system by performing a multiple regression analysis on time-series data over a certain period of time about the CPU usage rate of the entire system and the CPU usage rate of each process and compares the prediction value with a target value; and a process suspension control unit that controls suspension and resumption of said control-target process based on the result of comparison by said comparison unit, wherein an upper limit value and a lower limit value are set as said target value of the CPU usage rate of the entire system, and said process suspension control unit suspends said control-target process if said comparison unit determines that said prediction value is greater than said target value, and resumes execution of the control-target process if said comparison unit determines that the prediction value is smaller than said target value and said control-target process is suspended.
