Estimation of reliability characteristics and signature of binary-state flow networks

In this research, we assess the reliability characteristics of various networks, using the universal generating function (UGF), based on the flow of information/signals from a source node to a sink node. The basic aim of this paper was to demonstrate how the UGF can be adopted to solve the problems related to the network in which considering failure time distributions to be exponentially distributed. To measure the contribution of component (edge) in the system, sensitivity analysis plays a vital role in reliability analysis. The sensitivity measure is the same as Birnbaum importance measure. Moreover, for computing network signatures using Owens’s method, we assumed that all components are independent and distributed identically. Two networks, viz. bridge network and two-ring network, are considered to illustrate the proposed algorithms.
