Given the ubiquitous nature of infrastructure networks in today's society, there is a global need to understand, quantify, and plan for resilience these disruptions. This work defines network along dimensions reliability, vulnerability, survivability, recoverability, quantifies as function component performance. The treatment vulnerability recoverability random variables leads stochastic measures resilience, including time total system restoration, full service specific α% resilience....
AbstractModern supply chains are increasingly vulnerable to disruptions, and a disruption in one part of the world can cause difficulties for companies around globe. This article develops model severe chain disruptions which several suppliers suffer from disabled production facilities firms that purchase goods those may consequently shortage. Suppliers choose management strategies maintain operations. A supplier with facility move an alternate facility, firm encountering shortage be able use...
Theory, methodology, and applications of risk analysis contribute to the quantification management resilience. For analysis, numerous complementary frameworks, guidelines, case studies, etc., are available in literature. resilience, documented sparse relative untested definitions concepts. This essay on resilience analytics motivates tools, processes that will achieve real systems. The paper describes how analysts lead modeling, quantification, for a variety systems subject future...
Recent studies in system resilience have proposed metrics to understand the ability of systems recover from a disruptive event, often offering qualitative treatment resilience. This work provides quantitative and focuses specifically on measuring infrastructure networks. Inherent cost are introduced: loss service total network restoration . Further, “costs” shared across multiple infrastructures industries that rely upon those networks, particularly when such networks become inoperable face...
As intermodal hubs connecting barge, train, and truck transportation modes, inland ports play an important role in U.S. global commerce. Like coastal ports, face the risk of malevolent attacks, man-made accidents, natural disasters. However, most port impact studies focus on consequences one these disruptive events suddenly closing a port. This paper examines economic by combining simulation multiregional input-output model. The models how companies may react if waterway closes, dynamic...
