Traditionally, decision support tools for complex human-Earth systems are based on the principle of optimization of a utility, costs, or other objective function in a stylized modeling framework. ASA research within the Optimal behavior of systems group develops models which allow a better understanding of the behavior of particular human-Earth systems and of the methods used to analyze those models, such as optimization theory, control theory, theory of dynamic systems, game theory, and other related fields.
Treating natural and human-made systems as networks allows the interdependence of their parts to be addressed in a tractable way. Considering dynamic networks allows systemic risks to be addressed and resilience investigated. ASA research within the Interactions within systems group uses graph theory, information theory, network analysis, and other related fields and develop network-based modeling and assessment frameworks to analyze social, economic, material, energy, and other networks.
ASA research within the Systems’ flips and resilience of systems group experiments with qualitative and quantitative methods and approaches to studying systems resilience by analyzing possible shock/stress scenarios. ASA develops novel methods of data analysis that aim to identify precursors and general patterns via learning from the past.
The Advanced Systems Analysis (ASA) Program develops models that explain the behavior of particular human-Earth systems; it also advances methods of optimization theory, control theory, theory of dynamic systems, game theory, and other related fields that are used to analyze those models. More
