Reliability Modeling and Analysis in Random Environments

We consider a number of models where the main emphasis is on the effects of random environmental changes on system reliability. They include complex hardware and software systems which operate under some set of environmental states that affect the failure structure of all components. Our discussion will be of an expository nature and we will review mostly existing and ongoing research of the authors. In so doing, we will present an overview of continuous and discrete-time models and their statistical analyses in order to provide directions for future research.
