Simulation & modeling

Researchers in Safety and Security at the Division of Human-Centered Systems use several kinds of simulation and modeling in research projects for various purposes. Also, we develop simulation and modeling concepts and tools to be used in research and development.

Simulations can be used to simulate environments that people interact with, synthesizing critical aspects of real-world environments and tasks that are subject of scientific investigation. Simulations offer great benefits of cost-efficiency, safety, and controllability of these environments. Within the area of crisis and emergency management we have experience with the design, preparation, performance, and analysis of various forms of emergency management exercises, operational and role-playing games. Also within the area of command and control, and dynamic decision making, we use various microworld simulations, such as C3Fire and DKE, which simulate critical aspects of (command and control) decision making in complex and dynamic, yet controllable environments. Other researchers specialize in epidemiological simulation which is a highly actual research topic in societal security research.

Various modeling tools and techniques are used and developed in the area of Safety and Security. Within the areas of cognitive systems engineering, systemic safety, and resilience engineering we have knowledge of and experience with goals-means task analyses (GMTA) and functional resonance accident modeling (FRAM). These techniques have been developed to be able to cope with the complexity that is often exhibited by safety-critical socio-technical systems, with the purposes of aiding the design of work tasks and environments, risk analysis, and accident prevention. Other researchers specialize in modeling database material related to planning of catastrophe interventions and modeling of crisis response.
