| contents | The establishment of the time interval between inspections for a cold standby system with component repair Angélica Alebrant Mendes José Luis Duarte Ribeiro Ingeniería Cold standby Availability Markov process Cost optimization Periodic inspections The time interval between inspections of cold standby systems is a crucial decision to ensure the appropriated system reliability and the lowest costs possible. This paper presents a model developed to establish the optimal time interval between inspections for a two-unit cold standby system with component repair and subject to periodic inspection, considering reliability and costs. A Markov chain is used to define possible states, their transition probabilities and the mean time to system failure, as a function of the time interval between inspections. Given the mean time to system failure, the steady state availability is determined. Finally, the costs related to the system maintenance are established and a cost function is developed and optimized for the time interval between inspections. Numerical examples are presented and results for different system parameters are compared. Besides optimizing the time interval between inspections, the analyses also reveal the effect of repair time on system availability and mean time to system failure. 2017 artículo científico 0103-6513 https://www.redalyc.org/articulo.oa?id=396751070010 https://www.redalyc.org/journal/3967/396751070010/ https://www.redalyc.org/journal/3967/396751070010/html/ https://www.redalyc.org/journal/3967/396751070010/396751070010.epub https://www.redalyc.org/journal/3967/396751070010/movil 10.1590/0103-6513.004917 en http://www.redalyc.org/revista.oa?id=3967 Production application/pdf Associação Brasileira de Engenharia de Produção Production (Brasil) Vol.27 |
