Modelado estocástico de confiabilidad para activos físicos reparables. Caso de estudio aplicado a la minería chilena

Abstract

 The reliability modelling, calculating and projecting for  industrial equipment and systems are today a basic and  fundamental task for reliability and maintenance engineers,  regardless of the nature or genetics of those industrial assets.  In this paper, the stochastic models PRP, NHPP and GRP  are explained in detail with the corresponding conceptual,  mathematical and stochastic development. For each model,  the respective conceptualization and parameterization is  analysed in detail. The practical application is developed for a  real case in the mining industry, which shows step by step the  appropriate stochastic and mathematical development. Finally,  this research becomes an analytical and explanatory procedure  on the definition, calculation, methodology and criteria to be  considered for industrial assets parameterization with partial or  null post maintenance degradation.
