Integration of maintenance in the enterprise: Towards an enterprise modelling-based framework compliant with proactive maintenance strategy

Abstract

The aim of this paper is to propose an enterprise modelling-based formal framework Architectures for Enterprise Integration (London: Chapman & Hall), Vernadat 1996, Enterprise Modeling and Integration, Principles and Applications (London: Chapman & Hall)], as a common model of understanding between all the actors involved in a proactive maintenance strategy implementation. This enterprise modelling-based formal framework extends GERAM and CIMOSA modelling frameworks to integrate, from the shop-floor level to the business one, the three basic \\[Bernus et al . 1996, processes of prognosis, diagnosis and monitoring which make up a proactive maintenance system. This extension is mainly based, first, on the systemic paradigm taking into account some other principles (e.g. modularity or mapping mechanism); and second, on the federation of scientific and normative works related to maintenance processes (i.e. model-based diagnosis, IEC 191- 1990, etc.). This formal framework has been applied within the European ESPRIT IV REMAFEX project to two hydropower plants for maintenance system modelling. The results of these methodological and applied researches from PhD thesis (Le´ger 1999, Methodological contribution to the proactive maintenance of the industrial production systems: proposition of a formal modelling framework. PhD thesis of the Nancy University Henri Poincaré, France) have been the roots to start up the innovative PREDICT company for consulting, training and software development in proactive maintenance area.
