Abstract:

We discuss a reliability model which reflects the dynamic dependency between system failure and system stress. In particular, a shot-noise process is used to model residual system stress which in turn drives a doubly stochastic Poisson process model for system failures. Intuitively, residual stress or susceptibility to failure may vary in a random manner yet be essentially unobservable, while system failures may be readily detectable and observable. Shot-noise distributions have a richness and subtlety which suggest untapped potential for applications. The doubly stochastic Poisson process provides a reasonable framework for modeling randomly varying rates of occurrence in a broad variety of settings. Author
