Then, a path-based recursive decomposition algorithm and a cut-based recursive decomposition algorithm are derived to calculate the seismic reliability of lifeline networks. These two algorithms can enumerate the disjoint minimal paths and the disjoint minimal cuts simultaneously. As the result, a probabilistic inequality can be used to give the approximate reliability. Based on seismic reliability analysis of lifeline networks, a topology optimization model is established. The goal of the model is to find the least-cost network which satisfies specified seismic reliability. Combining with the path-based recursive decomposition algorithm, three optimization algorithms, genetic algorithm, simulated annealing algorithm and simulated annealing genetic algorithm, are presented to obtain the optimal solutions. Above approaches have been used to a practical gas network.
