Modeling Reliability of Critical Infrastructures with Application to Port Oil Transportation System

Abstract

A new approach to reliability investigations of multistate complex systems with dependent components at variable operation conditions called critical infrastructures is proposed. The multi-state reliability function of the critical infrastructure system is defined and determined for an exemplarymout oflcritical infrastructure. In the developed model, it is assumed that the system components have the multistate exponential reliability functions with dependent departures rates from the subsets of the reliability states. The model is adopted to reliability prediction of an oil piping transportation system operating at maritime port.
