Abstract

A procedure was developed to restore operability of the fault-tolerant digital systems with dynamic redundancy. A method of reconfiguration of the fault-tolerant graph, which allows one to use the redundant chords to eliminate the effect of the faulty chords of the working configurations of graph, was described. Indiscriminability of the faults of adjacent components does not inhibit restoration of operability of the fault-tolerant systems with dynamic redundancy. A procedure of single diagnosis of faulty components was developed with regard for the characteristics of the model. For some fault situations of the 2-fault-tolerant vertex 3-cube, examples of realization of the main stages of the restoration procedure—diagnosis of the faulty components and change of the working configurations—were presented.
