摘要

Voting algorithms have been widely used in the realisation offault-tolerant systems. We propose a new software voting algorithm whichuses the history record of redundant modules to compute the finaloutput. Two versions for the novel algorithm are introduced In the firstversion any module result is assigned to a weighting value such thatmodule results with higher history record value, are assigned to ahigher weighing value than those with lower history record value. In thesecond version of the novel voter, those module results which have ahistory record value, less than the average record value, are allocateda weight of zero and removed from the contribution toward the voteroutput. Furthermore, a novel method for creation of a history record ofmodules is proposed. Empirical results show that both versions of thenovel voter give higher safety performance than the Standard WeightedAverage voter with permanent and transient errors
