This work is motivated by modelling of real information systems. Parallel and series reliability models or their combinations are usually used for these tasks. Common assumptions for such models are independent failures, exponentially distributed failures and recoveries. These assumptions...

This paper is a continuation of the previous author’s research on the ergodicity of some models for queuing networks. The set of random graphs and the sequence of matrices describing the changing network structure has been used instead of the fixed graph here. The main results about ergodicity...
