The authors employ stochastic simulation in a reliability analysis of a regional water distribution network. The proposed stochastic simulation is aimed at evaluating the impacts of component failures on meeting demand at a certain quantity level and is intended to complement the connectivity-based reliability analysis presented in a previous paper. Simulation is conducted in a manner such that a sampling experiment of the system performance is repeated a sufficient amount of times and the results are analyzed to derive the desired reliability index. Given the mean time to failure and repair time of links, many synthetic system conditions are generated and operations of system under various conditions are simulated. Stochastic simulation of the system is conducted with a highly efficient embedded generalized network flow model to determine the optimal system operations for each scenario. The proposed reliability analysis method is applied to the water distribution network of the Metropolitan Water District of Southern California.
