In order to improve the reliability and safety of 2-out-of-3 safety computer system,this paper analyzes the different 2-out-of-3 voting models.They use the logic gates as minimal system unit and simplify the original voting model by different logical combinations.By analyzing these models according to Markov modeling method,it calculates the reliability and safety of Special-1 model,Special-2 model,and compares the results with Classic model.Comparison results show that the Mean Time to Failure(MTTF) of designed Special-1 model is higher about 10% than Classic model,and reliability is 0.333.
