In a network reliability evaluation, it is a problem to compute the probability that two specified nodes can communicate with each other in a given network, where each link breaks down with a some probability.
This paper is concerned with the network reliability evaluation in which switch failures also occur with some probabilities.
Binary Decision Diagrams (BDDs) are widely used for computing the strict probability of the reliability.
In this study, an algorithm directly constructing a BDD on the hypergraph converted from the input network graph is proposed.
A theoretical analysis of the algorithm is presented.
By appropriately determining the order of processing links and nodes, it is shown that the proposed method reduces the computation time and the memory usage by numerical experiments. |
