Complex systems is an approach to science, engineering, health and management that studies how relationships between parts give rise to the collective emergent behaviours of the entire system, and how the system interacts with its environment.
Systems are considered complex when their dynamics cannot be easily predicted or explained as a linear summation of the individual dynamics of its components.
We draw together top researchers from CSIRO and across the University, including:
Our research has an impact on diverse areas such as neuroengineering, epidemic modelling, active matter, systemic risk analysis and crisis forecasting, disaster and emergency management, as well as critical infrastructure stability.
It helps to develop solutions that can be applied to a wide range of industries including information and communication technologies, financial services, health, energy and civil and transport infrastructure.
CRISIS is funded as a Sydney Research Excellence Initiative (SREI 2020). It centres on the research project 'Modelling social risks and extreme events: from Angkor's demise to Australia’s housing crisis'.
This research program examines the greater Sydney area in 20th-21st centuries and the greater Angkor area in the 13th-14th centuries.
It will develop a cross-disciplinary framework for analysis, modelling and design of adaptive urban systems resilient to stresses, using advanced techniques from complex systems, network science, agent-based computational modelling, and dynamical systems.
Outcomes will include precise and efficient methods for forecasting critical dynamics during urban transformation, a computational model (including scaling of settlement sizes), calibrated to Australian datasets, and a software simulator of possible interventions.
