INDUSTRIAL SYSTEM FUNCTIONING/DYSFUNCTIONING-BASED APPROACH FOR INDICATOR IDENTIFICATION TO SUPPORT PROACTIVE MAINTENANCE

摘要

Failure Mode, Effects and Criticality Analysis (FMECA) is a well-known method used in safety analysis, reliability analysis, risk assessment and maintenance objectives. Moreover, in the manufacturing domain and particularly in the context of the deployment of the factory of the future, its usage is not entirely satisfactory in relation to the indicator to be observed. Thus, the paper presents a new methodology based on a coupled approach of FMECA and Hazard Operability analysis (HAZOP) which aim is to contribute to the deployment of proactive maintenance strategies by clearly identify pertinent indicator. This approach is based on the formalization of concepts of knowledge which permit to constitute the first pillars of proactive maintenance approach. Applicability of this methodology is illustrated on a machining center sub-system.
