Abstract : The basic reliability characteristics of a single computer and of a homogeneous universal computer system with reserve and recovery are considered. Their basic properties are determined: reliability functions, frequency of breakdown, average time of proper operation, degree of failure and recovery functions. Practical results obtained in verifying the reliability formulas for the Minsk-2 computer are described. Functions of readiness, reliability and recovery for universal computer systems with reserve and recovery are investigated. A general approach is developed for computing the reliability of such systems. The Erlang method is used to investigate several methods of restoring computer systems which are most frequently encountered in practice. Results of computing the readiness factor and evaluating the reliability functions as well as the recovery time for the Minsk-222 computer are presented. (Author)
