The IEEE CogSIMA conference aims to provide an annual venue for presenting multi-disciplinary research on complex heterogeneous dynamical systems – including humans, physical systems, computer agents and networks – whose individual and/or collective behavior depends on complex situations. Common to these systems is the need to adequately perceive, reflect, act, and communicate according to the current situation and expected changes, both in the surrounding environment and within the systems themselves. The amount of information that needs to be processed in order to derive decisions typically poses significant challenges for both human cognitive capabilities and computer processing power. Consequently, there is a need to develop novel situation awareness and decision support approaches for augmenting the capabilities of collaborating humans and computer agents.
