Advanced Systems Analysis

IIASA leadership of the field of systems analysis continued in 2015, and the institute hosted its first Systems Analysis conference, bringing together international researchers to discuss the current state and future directions of the field. IIASA-led advances in systems analysis in 2015 contributed to reducing the risk of collapse in financial networks and understanding uncertainty in estimating greenhouse gas emissions, among many other examples.

Managing uncertainty in climate science and meeting sustainability constraints

Greenhouse gas (GHG) emissions are a particular challenge for sustainability. Decisions need to be made now to avoid unsustainable futures, but the basis for these decisions, in terms of both data and models, encompasses vast inherent uncertainties. Proper accounting of uncertainties when verifying mitigation efforts and analyzing scenarios of future emissions is the focus of several Advanced Systems Analysis (ASA) Program studies. more

Modeling and optimal management of size-structured biological populations

Advanced Systems Analysis (ASA) Program researchers develop and analyze stylized models of biological populations (e.g., fish or 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 identify those, which can optimize typical economic (e.g., profit) and environmental (e.g., biodiversity) objectives. more
