Abstract :
In this paper, we develop the AVTMR (all voting triple modular redundancy) system that is operated correctly in the case of a fault, and evaluate the AVTMR system in the failure rate based on MILSPEC-217F. The AVTMR system is designed in a triplicated voter and MC68000. The Markov model is designed to evaluate the reliability, availability and MTTF (mean time to failure). In this paper, we can see that the AVTMR system has a high dependability more than a single system by evaluation. Because the AVTMR system has a fault tolerant characteristic, it can be applied to airplane and railway systems
