Abstract

A parallel system with n identical units is considered, and its mean time to system failure (MTTF) is obtained when the failure time is exponential. A simple asymptotic method of computing MTTF is proposed and its approximal values are compared with the exact MTTFs when the failure time has a Weibull distribution. It is of great interest that such asymptotic methods give good approximations to exact MTTFs. Furthermore, when the number of units is random, the MTTF and an optimal number of units to minimize the expected cost rate are derived.
