Abstract (English):
A model of a parallel computing process with temporary redundancy in a fault-tolerant on-board computing system under external influences is presented. A computational process is described, including periodic preservation of the current state of calculations with the possibility of their restoration. A particular optimization problem of choosing the periodicity of maintaining the current state of the computing process under possible external influences is solved. An algorithm is described for planning parallel processing of information in a fault-tolerant UAV with periodic preservation of the state of the computing process and its restoration during degradation of the UAV. A simulation model of the functioning of a fault-tolerant UAV is presented when solving target tasks under conditions of external influences, an analysis of the results of modeling parallel data processing is given.
