PURPOSE:To display equipment to be preferentially monitored at each time successively, by forecasting a system trouble, which is easiest to occur, on a basis of internal state quantities and input/output values of equipment constituting a plant system or the like and attaining a combination of troubles of devices which is the cause of this system trouble. CONSTITUTION:Internal state quantities and input/output values of equipment 102a-102n of a plant 1 are detected by detectors 103a-103n, and signals 104 are inputted to an analyzer 106 of equipment to be preferentially monitored. The analyzer 106 analyzes these signals and attains relations between them and troubles on a basis of data of preliminarily held system troubles and data of signal values and determines a trouble event to be noticed. Next, a cut set of system troubles is attained, and importance equipment are extracted by probability calculation to forecast the occurrence of the system trouble, and several important constituting devices are displayed on a display device 107 for the purpose of preventing the system trouble. A monitor inputs required operations from an input device 109 to report them to a controller 108.
