Estimate the individual part failure rate given a base failure rate of failure/hour, a quality factor of and an environmental stress factor of Sol.) . p = b Q e = ( )( )( ) = 2. Three components each with a Reliability of are placed in series. What is the Reliability of the System ? Sol.) The System Reliability is the product of the component reliabilities. . Rs= 3. The components in the System below are exponentially distributed with the indicated failure rates. Develop an expression for the Reliability of the System . What is the System Reliability at time = 100 hours ? Chapter 5 : System Reliability . - 2 -Sol.) For the exponential distribution, the Reliability R(t)=e- t - The Reliability of the System .
