Advanced Systems Analysis

Advanced Systems Analysis—exploratory applied mathematics—is IIASA’s “operating system,” allowing scientists to evaluate and assess some of the most persistent and pervasive problems of our time.

Identifying common sources of population heterogeneity

The World Population Program (POP), with three other IIASA programs—Energy (ENE), Mitigation of Air Pollution and Greenhouse Gases (MAG), and Ecosystems Services and Management (ESM), has begun to implement the crosscutting project “Accounting for socioeconomic heterogeneity in IIASA models.” more

Indirect effects and informational entropy in natural and human networks

Advanced System Analysis (ASA) Program researchers develop methods and case-studies analyzing ecological, economic, energy, financial and other networked empirical systems. These methods often originate in the natural science disciplines (e.g., physics, ecology) and then transfer to social sciences disciplines (e.g., economics). more

Advanced Systems Analysis Forum

Important progress was achieved by scientists of the Transition to New Technologies (TNT) Program in a number of in-house collaborative research projects and externally funded research contracts, including a project within IIASA’s Advanced Systems Analysis Forum. more

Attainable solutions and model sensitivity

Advanced Systems Analysis (ASA) Program researchers advance methods of control theory that allow models of complex human-Earth interactions to be studied under incomplete information and uncertainty. more

Endogenous economic growth: Drivers and impacts

Advanced Systems Analysis (ASA) Program researchers develop and study stylized models of endogenous economic growth in which long-term economic growth is generated by such factors as physical and human capital. An extended form of these models also includes feedback with the environment. more

Equitable governance of common goods

A new interdisciplinary cross-cutting project aims to narrow the gap between case studies and mathematical models by focusing on formal and informal institutions for overcoming the tragedy of the commons, using experimental games and agent-based models as stepping stones. more

Food-energy-water nexus: Robust solutions

Through case studies, Advanced Systems Analysis (ASA) Program researchers model interconnected food, water, and energy systems at the local and global levels with the aim of suggesting robust management strategies with respect to uncertainties and risks. more

Income inequality and heterogeneity

The Energy (ENE) Program contributed to a cross-cutting collaborative research project by developing projections of future national income distributions. more

Optimal management of heterogeneous resources

Advanced Systems Analysis (ASA) Program researchers develop and study stylized models of management of heterogeneous resources to allow them to analyze size-structured populations, such as fish and forests; the aim is to understand the consequences of various management strategies and also to reveal which management principles can optimize certain economic and environmental objectives. more

Optimal spreading of risks

Advanced Systems Analysis (ASA) Program researchers have developed a framework to produce policy instruments that are robust with respect to potential uncertainties to combat growing risks from natural hazards. more

Resilience of regional economies

Advanced Systems Analysis (ASA) Program researchers are developing agent-based modeling frameworks that simulate economic agents (individuals, firms, banks, and so on) and their interactions under different regulations and input scenarios. more

Systemic risk and network dynamics

The increasing interdependence of critical systems such as financial markets, food-supply chains, and energy grids poses new challenges for risk management, which must account for cascading failures propagating across a network of dependencies. more

How to improve air quality in China: A policy scenario study

Jun Liu of the College of Environmental Sciences and Engineering, Peking University, Beijing, China, explored the potential benefits in terms of air pollutant reduction through natural gas substitution strategies in power plants, residential combustion, and industrial boilers in the Jing-Jin-Ji region. more

Abstract algebraic tools for systems analysis

Daniel Jessie of the Advanced Systems Analysis Program is working to introduce a different mathematical approach to understanding the nature of dynamical network processes where standard mathematical tools can only provide analytical solutions in simplest cases. more

Behavioral equilibrium for infinitely repeated games

Artem Baklanov of the Advanced Systems Analysis Program is analyzing iterated social dilemmas that will help reveal features of stability of interactions, thereby helping individuals learn, though interaction, how to cope with behavioral uncertainty, understand the interests of other individuals, and better adapt to changing social environments. more

Dynamics in large, complex networks

Matthias Wildemeersch is working in the Advanced Systems Analysis and Ecosystems Services and Management Program on the dynamical behavior of large-scale networks with the aim of strategies to improve network robustness. more

Modeling soil carbon and nitrogen cycling based on microbial ecology

Christina Kaiser is working in the Evolution and Ecology Program using a computer model that she developed and tested herself which simulates decomposing litter or soil at microbial-relevant scales to understand mechanisms emerging from complex microbial interactions at the microscale. more
