Optimal behavior of systems

Within the area "Optimal behavior of systems" ASA research focuses on how making decisions that govern systems’ behavior can be formalized in models, notably, under uncertainty and risks, and what consequences different decisions yield. 

Decision support tools and applications are developed, which are traditionally based on the optimization of a utility describing decision-maker’s preferences. In this domain, ASA researchers employ and advance methods of optimization theory, control theory, theory of dynamic systems, and other related fields. Applications mostly focus on economic models, notably, long-term economic growth (also under environmental constraints) and resource management models. 

Drivers and impacts of economic growth: Modeling and control 

Advanced Systems Analysis (ASA) Program researchers develop and study stylized economic growth models and advance methods of the optimal control theory needed to analyze such models. Long-term economic growth is driven by the dynamics of natural, physical and human capital; an extended form of these models also includes feedback with the environment under uncertainty. More

Robust solutions for food-water-energy nexus 

Advanced Systems Analysis (ASA) Program researchers model interconnected food, water, and energy systems and advance methods of stochastic optimization with the aim of suggesting robust management strategies with respect to inherent uncertainties and risks. More

Modeling and optimal management ofsize-structured biological populations

Advanced Systems Analysis (ASA) Program researchers develop and analyze stylized models of biological populations (e.g., fish and forests), in which individuals’ growth significantly depends on their size or age and on the size or age of others. The aim is to understand the consequences of various management strategies and to reveal which management principles can optimize typical economic (e.g., profit) and environmental (e.g., biodiversity) objectives.
