For assessing the seismic reliability of large scale lifeline networks we developed an algorithm which had only polynomial complexity to enumerate paths in the network. Using this algorithm we have developed two program packages. One is composed of a vectorized program to increase computing efficiency and the other is a program coded by a new approximate calculation scheme, named as the point matching method. The vectorized program can solve seismic reliability of a network with up to 3500 elements using the super computer, FACOM VP-400E. If the number of elements of network exceed 3500, only the point matching method can provide a feasible solution from the practical stand point of computing time. This program can also ran on a 32 bit desktop computer with the main memory of 16 MB and the operation time of 5.3 MIPS. This program package offers you an interactive capability, to select supply and demand nodes as well as show them on screen. To check the applicability of the program package, we considered a gas supply network composed of 3529 elements. キーワード（英）： - 記事区分： - 区分 　　　委員会論文集
