The process monitoring and diagnosis system is provided with a process modeling and supply unit (4) and a process monitoring and diagnosis unit (6) to monitor and diagnose processes. The process modeling and supply unit (4): collects time-series data for multiple instrumental variables comprising state quantities and operation quantities of processes to be measured by multiple process sensors in a predetermined cycle; has a unit for collecting and storing data (2) that is kept; and uses the previous time-series data of multiple instrumental variables that have been stored to construct and supply process monitoring models. The process monitoring and diagnosis unit (6) monitors process states and detects state changes and abnormal signs by using online data extracted from the unit for collecting and storing data (2) and the process monitoring models that have been constructed.
