Confiabilidade Autovalidável para Sistemas com Processo de Falhas Exponencial

Abstract: RESUMO.A computação da confiabilidade envolve números reais, o que gera problemas numéricos decorrentes das limitações encontradas na manipulação de reais em máquinas digitais. Este trabalho propõe um método, implementado no Matlab utilizando a biblioteca Intlab, para a obtenção de intervalos que encapsulam valores de confiabilidade real de sistemas com processo Exponencial de falhas, controlando erros numéricos. O software SHARPE foi empregado para validar o método implementado.Palavras-chave: intervalo encap… Show more

“…In [4] it is outlined a focus in providing intervals to reliability based on Bayesian analysis. The work of [16] presents interval enclosures for reliability function values of systems with Exponential failure distribution. This paper has a new approach that is focused on computing intervals that bound numeric errors introduced during computation process of reliability metrics in digital machines for Exponential, Weibull and Normal failure distributions.…”
