Contribution à la maintenance proactive par la formalisation du processus de pronostic des performances de systèmes industriels

Abstract : Today requirements and constraints on industrial systems about economic, safety, ecological... points of view lead to consider their performances with a global view taking into account all the system lifecycle. Thus the design of the system-of-interest has to be connected as soon as possible with the enabling systems designs, and more particularly the logistic support based on the key process of maintenance. This new consideration about maintenance allowed to change practices from reactive to predictive ones with the emergence of the proactive maintenance built on the prognostic process. However this process still lacks of generic formalization and existing works focus mainly on component level without tackling system performances. Therefore our contribution is related to the modelling of generic architectures for the systems prognostic which assesses future evolution of degradation/failure components and system/subsystem/component level performances: either by prognosticating with an adapted model, or by modelling the dysfunctional causality with logical relations supported by a neuro-fuzzy tool ANFIS. A methodology is given to define indicators for degradations and performances and to build architecture. Finally, the feasibility of this approach is shown on the manufacturing TELMA platform.
