In order to prevent faults, many methodologies have been proposed for process monitoring. When it is difficult to obtain a classical model, the use of fuzzy clustering techniques allow the identification of classes that can be associated to the process functional states (normal, alarms, faults). This paper presents a methodology for predicting functional states in order to prevent critical situations. Using the process historical data and combining fuzzy clustering techniques with Markov's chains theory a fuzzy transition matrix is constructed. This matrix called WFT is used later online in order to predict the next functional state of the monitored process. The methodology was tested in a boiler subsystem, and a water treatment plant. © Springer-Verlag Berlin Heidelberg 2012.
