  • Renewal Process

    Consider a system consisting of N components, all working independent of each other, and with life spans of each component exponentially distributed with mean ?^(-1).When a component breaks down, repair of the component starts immediately and independent of whether any other component has broken down. The repair time of eachcomponent is exponentially distributed with mean ?^(-1). The system is in state n at time t, if there is exactly n components under repair at time t. This is a birthand death process.Let ?=? and assume that all N components are working. Find the distribution function F(t) of the first time, when 2 components does not work.
