Reliability of an m-out of-n system when component failure induces higher failure rates in survivors

An m-out-of-n:G system is composed of statistically independent and identically distributed components with exponential lifetimes. The reliability of such a system is obtained under the assumption that the failure of a component changes the failure rate of the surviving components.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
