Abstract
The subject of the research is a duplicated computer system, which contains means of operational and test control, and will be considered as a basic computer node for infocommunication systems of responsible meaning. There are different ways of organizing system control: testing of only one node, testing of only two nodes and testing whether one or two computer nodes. Besides the functional and the failed states of the system, there are dangerous conditions that may be not detected by control malfunction. The inbound flow of requests is heterogeneous - there are non-critical requests as well as critical, which require duplicated computations. The aim of the work is to choose a discipline of test control and define optimal intervals of testing initialization that ensure the maximum probability of the system’s readiness for safe implementation of functional requests for different flows of requests. Research method is based on constructing a Markov model.
