PROBLEM TO BE SOLVED: To deliberately execute the parameter adjustment work of a process. SOLUTION: The process monitor controller stores the subsequent fluctuation of a specified process in a process data storage means 3 as process data at a prescribed period whenever a parameter setting value is changed at the time of executing the detection work of an optimum value while the prescribed control parameter setting value is changed. For changing the parameter setting value for several times and detecting the optimum value from the situation of the fluctuation of process data in respective cases, the change time of the parameter setting value at respective times is set to be start time from the process data storage means 3 with the change time of the parameter setting value for respective times as keys. Plural groups of process data whose collection time differ are read and plural time fluctuation graphs by setting change time as a common condition to be start time is compared and displayed in a graph display means 9. Thus, the optimum value of the parameter is decided from the situation of the time fluctuation of the plural displayed graphs.
