The development of radio-electronic industry leads to rapid growth of functionality of manufactured products and complication of radio engineering systems (RES) structure at simultaneous increase in the requirements to their reliability. The aim of this work is the development of general methods to research reliability of RES allowing to consider various algorithms of configuration and reservation of systems with restoration. The model of refusal stream for RES with restoration is accepted taking into account the introduced restrictions. The algorithm of differential equations formation to determine the probability of RES states with refusals and restoration is offered. Calculation of readiness function for RES with restoration without reservation is given. The order of calculation of readiness function, readiness coefficients and idle time for RES with restoration and duplication is shown.

Key words: aprioristic reliability, radio engineering systems (RES), state graph, reservation, streams of refusals and restorations.
