Abstract
For the counting process N={N(t), t≥0} and the probability that a device survives the first k shocks\(\bar P_k \), the probability that the device survives beyond t that is\(\bar H(t) = \sum\limits_{k = 0}^\omega {P(N(t) = k)} \bar P_k \) is considered. The survival\(\bar H(t)\) is proved to have the new better (worse) than used renewal failure rate and the new better (worse) than average failure rate properties under, some conditions on N and\((\bar P_k )_{k = \rho }^\omega \). In particular we study the survival probability when N is a nonhomogeneous Poisson process or birth process. Acumulative damage model and Laplace transform characterization for properties are investigated. Further the generating functions for these renewal failure rates properties are given.
