Reliability Investigation of TMR and DMR Systems with Global and Partial Reservation

In this article are considered three types system structures: TMR ("2-of-3"), "2-of-2" global reservation by replacing and "2-of-2" with partition reservation by replacing. Here are considered formulas for calculation of reliability the indices "System Availability" and "Mean Time Between Failures." On this basis here is conducted an analytical research of the reliability of the three systems. In conclusion, here is made a comparative analysis to determine which structure under what conditions is most reliable.
