ASA Research Areas

Systems analysis treats the coupled human-environment as a hierarchical system of interacting systems. A particular research question employs one of the three possible levels of consideration.

Levels of analysis

Particular system: focus on decisions taken by a system within a larger system

Interactions between systems: focus on (dynamic) connectivity between systems

System of systems: focus on the state and dynamics of the entire complex system

Correspondingly, ASA’s research is organized around three mutually complementing and cross-fertilizing research areas.
