Cascade system reliability with Rayleigh Distribution

Abstract

The stress-attention in cascade reliability has been studied when both stess and strength follow Rayleigh distribution. The expression for the relaibility R(n), for a system survive with the first (n-1) components failed and the n component active, is obtained R(n) is calculated numerically, for n=1,2,3 and 4, for different values of the parameter p and the attention factor k. It has been found that with lower attention factors in high degree of reliability can be attained.
