| Summary: | 碩士 === 國立中興大學 === 統計學研究所 === 103 === This paper attemps to investigate the reliability and sensitivity analysis of a system with imperfect coverage and a repairable service station. Failure times and repair times of each unit are assumed to be exponentially distributed. With a coverage probability,a failed unit is immediately deteced and replaced by a standby if one is available. If the failed unit is not detected, the system enters an unsafe failure state and have to be refreshed by a reboot action. When the service station breaks down, it needs repair at a repair device. We present the expression for reliability function,Ry(t), mean time to system failure, MTTF. Several cases are analyzed to research the effects of various parameters on the system reliability and MTTF. Sensitivity analysis for the Ry(t) and the MTTF is also studied.
