| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Triple modular redundancy (TMR) is a major method that is used for implementing fault tolerant systems. In TMR, a module unit is triplicated, and the outputs of these three units are compared by a voter. A system connecting multiple TMR in series is called a cascading TMR system. Traditionally cascading single-voter TMR systems use voters of fan-out three.Recently, however, a new cascading single-voter TMR system configuration which uses voters of fan-out one was proposed. This study proposes a method of calculating the reliability of cascading single-voter TMR systems and an algorithm for finding the optimal configuration of a cascading single-voter TMR system. The method of calculating reliability uses a case-splitting based on the state of the values of the three lines in a cascading single-voter TMR system to calculate the occurrence probability of each state at every stage. The method of finding the optimal configuration of a cascading single-voter TMR system uses the branch and bound approach to explore the solution space effectively. | |
