A Meta Risk Model for Supporting Interactive Decision Making in Situation Awareness Centers

In this paper we introduce a meta risk model enabling an abstract view of risk management in general. The underlying open world assumption and the structured method of applying the model allows to consistently integrate various approaches and procedures for e.g. disaster classification, involved roles like first responders, local government, military or administrative personnel. Starting with the recently developed IT-specific model of RiskSense [3], which is using the catalogues of the German IT-Grundschutz, we provide a new possibility for interactive decision making, especially for the needs of Situation Awareness Centers (SAC). In this context, first responders can quickly and effectively gain necessary insights into potential risk factors and their dependencies. Additionally using the structured procedural Z-Model [14], information is gathered and analyzed to identify scenarios, feeding the functional meta risk model to enable transparent decision-making.
