In this article it is being studied a class of random discrete systems, developing polynomial algorithms for determining the basic characteristics of time evolution of their own. It is a generalized problem for the case when the transfer time of the system in the next state is also a random variable with known distribution law. The developed algorithms are based on probabilistic method of determining the characteristics of random variables, knowing the generating function or characte ristic function of them. Algorithms are being presented for numerical derivation of functions composed and rational fractions that appear later in main algorithms. It makes a brief foray into the theory of homogeneous linear recurring series to argue theoretically developed algorithms.
