Methods involving structural redundancy are of great importance in solving the problem of reliable operation of automatic control devices. This article examines certain fundamental possibilities of signaling or predicting breakdowns in automatic control devices. One principle previously described by the author which governs these possibilities is that determination of the minimum number of extra internal elements necessary to provide requisite reliability completely coincides with the problem of determining the minimum number of supplementary symbols needed to construct correction codes for the corresponding number of mistakes. This method involves construction of tables of states and relates to the case where failure probability is the same for all internal elements, element failures are symmetrical, and individual failures are independent. Other conditions demand a different approach. The discussion expands the application of this method.
