Maximum entropy model applied to Reliability Centered Maintenance scheme for replaceable systems
Autor: Marco A. Fuentes-Huerta, Octavio Perez Gomez Gaona, David S. González-González, Rolando J. Praga-Alejo
Publikováno v: 2019 International Conference on Mechatronics, Electronics and Automotive Engineering (ICMEAE).
Based on methodologies of variational calculus and differential entropy, we propose in this work a non-parametric model that provides a robust estimation of reliability to be used in a RCM scheme. A Weibull analysis is presented first in a case study

A non-linear fuzzy degradation model for estimating reliability of a polymeric coating
Autor: David S. González-González, Rolando J. Praga-Alejo, Mario Cantú-Sifuentes
Publikováno v: Applied Mathematical Modelling. 40:1387-1401
Oftentimes, material components follow non-linear degradation because the material loss trough time is non-linear; the components present different levels of resistance during a degradation process. Constructing predictions of the component life span
