The present work belongs to the field of decision support systems for complex process monitoring, such as chemical and petrochemical plants. Since it is not always possible to obtain a mathematical model for these processes, it is necessary to consider other approaches such as learning and classification methods, in order to identify their different operating modes (normal or faulty). We propose a strategy based on Data Mining techniques, which allows the construction of a discrete event model of the process behavior using historical and online data. This strategy consists on an offline learning stage for the elaboration of a first reference model. This model, in the form of a finite state automaton, must be validated and completed by the p...
