Background. The methodological basis of highly reliable equipment with limited reliability of its components is the reconfiguration of redundant systems. The task of the article is to present and analyze the results of statistical modeling of the system, that implements the approach developed by the authors to control the redundancy of the on-board equipment complex based on configuration supervisors with an assessment of various options for organizing their arbitration. Materials and methods. The structure and main provisions of a stochastic model reproducing the processes of paired arbitration of configurations using configuration supervisors, as well as simulating random malfunctions (failures) of various configuration components and errors (failures) of analysis modules forming a decision on the preference of a particular configuration of a technical system, conditionally unlimited in terms of resources, are proposed. The model reproduces three arbitration algorithm variants: simplified binary, full binary (preference indexes – binary variables) and triplex (preference indexes – triplex variables), as well as the algorithm of a simple comparator for comparative analysis by criteria of reliability of preference selection and completeness of error diagnosis of analysis modules. Results. Comparison of the simulated algorithms showed the variability of statistical indicators with the accumulation of uncorrectable errors contained in the configuration supervisors. For a relatively small number of errors (within the first thousand), a certain advantage of binary algorithms over triplex and overwhelming over comparator is shown. Conclusions. The use of proposed type paired arbitration algorithms will make it possible to implement the required levels of reliability of on-board complexes with an excessive number of heterogeneous resources.
