This paper is part of the DHSS Workshop (International Defense and Homeland Security Simulation). Airport is a highly dynamic environment, turning emergencies into extensively costly and disruptive events with cascaded effects that will adversely affect the entire aviation system. Airports' management and safety divisions exercise precise and case-based procedures to accommodate any possible emergency scenarios. With this regards, airport emergencies have a number of challenges that require better and more adaptive way of addressing. Challenges such as lack of adaptive and customizable simulation-based decision support tools, infeasibility of conducting frequent physical emergency exercises, and the time-critical nature of emergencies in general raise an immediate need for a technology that collaboratively performs modeling, simulation, and visualization to guide first responders throughout the decision-making process. Here we propose a collaborative emergency modeling, simulation and analysis software system that provides an all-in-one simulation technology for enhancing emergency response at airports.
