چکیده
Abstract: In this paper, we study the reliability measures of a repairable system with M operating units, W warm standby units, and R repairmen in which switching failures and reboot delay are considered. It is assumed that there is a significant failure probability q in the switching process. Failure times of an operating unit and of a standby unit are assumed to be exponentially distributed with parameters and , respectively. The delay times of reboot are also assumed to be exponentially distributed with parameter . The explicit expressions of the reliability characteristics such as the system reliability, ( ), Y R t and the mean time to system failure (MTTF) are derived. Several cases are analyzed graphically to investigate the effects of various system parameters on the ( ) Y R t and the MTTF. We also perform a sensitivity analysis for the reliability characteristics along with changes in specific values of the system parameters.

Performance Analysis of a Repairable Robot Safety System with Standby, Imperfect Coverage and Reboot Delay
The present study deals with a robot safety system composed of standby robot units and inbuilt safety unit. When the main operative unit fails, it is replaced by the standby robot unit available in the system. The concept of reboot delay is also incorporated in this study according to which the robot unit is rebooted if it is not successfully recovered. The recovery and reboot times of failed u...
