On a two-unit cold standby system considering hardware, human error failures and preventive maintenance

This paper deals with the study of the stochastic analysis of a two-unit cold standby system considering hardware failure, human error failure and preventive maintenance (PM). All time distributions are considered to be arbitrary. Various measures of reliability of the system are obtained using the regenerative point technique. All these measures are also derived based on time t 0 . (Practically PM can be performed after time t 0 from the beginning of the system operation.) Finally a simulation study is carried out to illustrate the result.
