Abstract in Portuguese
Neste trabalho apresentamos uma análise Bayesiana para confiabilidade de sistemas de redes usando métodos de simulação de Monte Carlo via Cadeias de Markov. Assumimos diferentes densidades a priori para as confiabilidades dos componentes individuais, com o objetivo de obtermos sumários de interesse. A metodologia é exemplificada condiderando um sistema de rede com sete componentes e um caso especial de sistema complexo composto por nove componentes. Consideramos ainda confiabilidade de redes tipo k-out--of-m com alguns exemplos numéricos

Abstract in English
In this work we present a Bayesian approach for network reliability systems using Marov Chain Monte Carlo methods. We assume different prior densities for the individual component reliabilities th to get the posterior summaries of interest. The methodology is exemplified considering a network system with seven components and a special case of complex system with nine components. We also consider k-out-of-m system reliabiility with some numerical examples
