One of the main limitations of the current plant supervisory control systems is the correct management of multiple simultaneous faults, which is crucial for supporting plant operators decision-making. In this work, Support Vector Machines (SVM) are used because of its proved efficiency dealing with multiclass problems in other technical areas. A Fault(More)
This work presents an alternative MILP mathematical formulation for the short-term scheduling of pipeless batch plants based on a continuous-time representation that relies on the general precedence notion. Besides of the intrinsic characteristics of a pipeless plant, this model considers the moveable vessels as an additional resource that has to be(More)
This work addresses the design and operation of treatment systems for processing a set of wastewater streams in the most efficient way, thus solving the trade-off given by the minimization of investment, operational and environmental costs. An open framework is proposed for solving treatment networks, including any kind of objective function or treatment(More)
In this paper, the Real Time Evolution algorithm (Sequeira et al., 2002) is applied to the on-line optimization of a debutanizer distillation column. A fault diagnosis system (FDS) implemented within a supervisory module is responsible for handling incidences (faults and disturbances) happening in the plant by taking the appropriate corrective actions,(More)
