The Impact of Integrated Maintenance Actions Optimization on Strategic Machines Lifetime

This article is based on the quantitative study of reliability, maintainability, availability (RMA), on the Pareto diagram (ABC) and on the analysis of the failure modes and their impact on criticality (FMECA). The developed approach aims, at first, implementing two optimization procedures (code development, Simulink modelling in MATLAB) and using two methods (graphical, analytic) of the Weibull parameters. The results obtained via code (which is based on the Weibull graph method of two parameters) are a bit divergent. The evaluation criteria are rather far from that of the model (which is based on the maximum likelihood of three-parameter Weibull distribution). This will allow to locate the critical elements, and to determine the systematic preventive time of replacements. An application case validates the proposed study objective.
