The simplest random point processes are considered for solving problems of reliability and safety assessment. The basic processes are the nonhomogeneous Poisson and the renewal process.

The developed methods are applied to modeling the reliability of software performance, to safety at sea assessment and to some other practical settings.

The systematic mathematical treatment of the general repair theory is performed for the first time in the literature. It is based on the notion of the generalized renewal process. A detailed description of applications of this theory is presented for solving the problems of planning accelerated testing and estimating the influence of random environment on a lifetime random variable to name a few.

The monograph can be helpful to those involved in reliability and safety analyses of various objects at different stages.
