Comparison of Two Approaches in Reliability Analysis for the Network of Trentinos Bridge Management System

The connectivity reliability of a network states the probability that the traffic can reach the destination from the origin. This paper is dedicated to find a reasonable and fast method to calculate connectivity reliability between any two nodes of a network. Monte Carlo simulation and ORDER algorithm are used and compared in getting the network connectivity reliability. The results show that ORDER algorithm can give more accurate bounds of connectivity reliability for network with high reliable components, while the computation time of Monte Carlo simulation is shorter than ORDER algorithm. Both approaches are applied to the network in the Bridge Management System in the Autonomous Province of Trento.
