Abstract
Provided are a reliability estimation system and a reliability estimation method capable of reducing a calculation amount of a reliability of a plurality of networks between terminals in communication between the terminals over the plurality of networks. The reliability estimation system according to the present invention calculates, for each network, a contraction reliability R, a contraction reliability R' when nodes are contracted, and a contraction reliability R′ between the networks including the terminals, and a true value of the reliability between the terminals over the plurality of networks is between a product P1 (=R′ R) and a product P2 (=R′ R′). Instead of calculating the true value of the reliability, only an upper limit and a lower limit are calculated, and thus, it is possible to significantly low additional remark the calculation amount.
