Analyzing the influence of Zeroth Responders on resilience of the Maritime Port Enterprise

Zeroth Responders are defined as the individuals who respond spontaneously prior to a coordinated response group. Their influence in both natural and man-made disaster response has been drawing attention to an increasing number of governmental, private and communities´ stakeholders. To effectively evaluate the influence of Zeroth Responder, and to better understand the challenge stated in the 2010 Department of Homeland Security (DHS) Quadrennial Homeland Security Review Report (QHSR): “neighbor-to-neighbor assistance, when done safely, decreases the burden on first responders, and individuals should be seen as force multipliers who may also offer specialized knowledge and skills”, this paper develops a quantitative resilience model that can be used to compute resilience figures-of-merit with focus of Zeroth Responders´ influence on the Maritime Port Enterprise. An initial Small Vessel Security threat scenario “Use of Waterborne Improvised Explosive Devices (WBIED)” is modeled to quantify the resilience on a port transportation network.
