Limites para a confiabilidade de sistemas usados com componentes com tempo de vida M I F R
Keywords in Portuguese
Teoria Da Confiabilidade
Abstract in Portuguese
Consideramos um sistema usado, sua deterioração no tempo e a dependência estatística e estrutural de suas componentes através dos processos de contagem associados com as falhas dos componentes e com a falha do sistema. Utilizando a teoria dos Martingales para processos pontuais e assumindo que conhecemos um momento ou um percentual obtivemos limites para a confiabilidade de sistemas usados, complexos e com componentes dependentes sob a hipótese de que a distribuição conjunta dos componentes é M I F R/'F IND.t' (Multivariate Incrasing Failure Rate) relativa a história dos componentes

Abstract in English
We consider a used system, its time deterioration and the statistical and structural components dependence through the counting processes associated with the components and system failure. Using martingale theory for counting processes and assumimg one moment or one percentile known, we get reliability for used complex system with dependents components under the assumption that the components joint distribution is MIFR (Multivariate Increasing Failure Rate) relative to the components history
