This paper presents a methodology for reliability assessment of large-size network. The algorithm used is based on a partioning of the nodes of the original network into subsets that can be systematically analyzed. The exact and approximate approaches are carried out to compare with the results based on the existing methodologies. This application is illustrated through numerical examples of two lifeline systems to examine the accuracy and efficiency of the present method. Examples are performed using the four methods, i. e., 1) present algorithm, 2) inclusion and exclusion method with transformation to equivalent network of series system in parallel (SSP network), 3) Boolean algebra method and 4) Monte Carlo techniques. The major conclusions obtained in this study are as follows : 1) The proposed procedure brings substantial reduction in huge computer storage reguirement and CPU time for determining the exact solution of a large network, when compared to existing algorithms based on state, path or cut-set enumeration and Monte Carlo simulation. 2) A lower bound on the reliability can be estimated by applying the equivalent SSP algorithm, which deals with strongly connected components, to the dual network. 3) Approximate algorithm with the upper and lower bounds corresponding respectively to path and cut-set enumeration can give the adequate estimate and is an effecive method for dealing with a large network. The upper and lower bounds are more accurate than the existing approximato methods. 4) The approximate upper and lower bounds of network reliability are close togeter to the exact solution under certain circumstances.
