PROBLEM TO BE SOLVED: To support selection of such a physical path in which influence due to a disaster relatively becomes small about a link added to a network.SOLUTION: A path length about each candidate path about a link added between a pair of nodes is calculated in each of a part or the whole of node pairs among a plurality of nodes constituting a network, a first index value showing the magnitude of influence due to an earthquake is calculated about each candidate path in each an assumed earthquake, and a subset is extracted from each candidate path on the basis of the path length of each candidate path about the pair of nodes and the first index value of each earthquake in each pair of nodes.SELECTED DRAWING: Figure 2
