Nowadays,reliability is moving toward interdisciplinary research with ever-increasing connotations for full life-cycle system management,including system design,analysis,modeling,test,operation,optimization,etc.Meanwhile,complex systems,such as transportation system,power system,communication system and other various critical infrastructure systems,have posed a big challenge,which attracts great attention both in theory and application.Characterized by nonlinear interaction,emergent response,and high dimensional coupling,the complex systems are in the face of extremely high uncertainty and vulnerability.Therefore,failure of these complex systems could cause even more dramatic cascading impacts,leading to huge losses of life and property.All these realities put forward more urgent requirements for the fundamental theory and specific application of reliability management of complex systems.
