| Abstract(in English) | This paper proposes a new algorithm for computing failure frequency of telecommunications networks. The proposed method is based on a special modification that transforms the formula for computing the reliability into a formula that also gives the failure frequency formula. While the path, cutset, and reduction methods have already been successfully transformed into failure frequency formulae, the most efficient method called as the factoring algorithm had not yet been transformed, because its graph operations contraction and deletion of a link become complicated in the check failure frequency. A new matrix-style decomposition formula is derived in this paper, and allows us to transform the factoring algorithm into an algorithm that gives failure frequency as well as reliability. Some numerical examples show that this new algorithm simultaneously computes both measures in high efficiency. |
