An on-line supervisory system extended for supporting maintenance management
This paper describes the issues involved in the provision of maintenance support functions integrated in an existing plant supervision tool called FORMENTOR. The FORMENTOR project developed methodologies, models and software tools, aimed at offering real-time decision support to operators of complex industrial plant. This paper discusses, in particular, the definition of, and the constraints imposed by, plant maintenance requirements, along with user needs. The essential functionalities of such a maintenance support system are described and it is shown how the FORMENTOR concepts and knowledge schemes provide a kernel for supporting an important part of these functionalities. The maintenance strategies that potentially benefit most from such a FORMENTOR based maintenance support tool are the ones that integrate information on equipment conditions into their decision making process. The support given by such a system is useful for early warnings on failures relevant for corrective actions and for achieving longer operation periods, along with the foresight of degraded equipment states in the case of preventive and predictive maintenance. Finally, the functionalities supported by such a tool are briefly illustrated by a case study, in the refining domain.
