Category: Complex Systems

Complex systems are ubiquitous in today’s world and they experience serious issues caused by emergent behavior, self-organization, and cooperation among their entities. Emergence becomes a distinguishing system feature as system complexity grows with the number of components, interactions and connectivity. Example of emergent behaviors include the flocking of birds, traffic jams, ant colonies, biological life, hubs in social networks, competition in energy power markets, smart grids, and smart cities among others. Despite significant research interest in recent years, there is a lack of formal methods to understand, identify, and predict the behavior of complex systems, especially as systems grow in size, inter-connection between components, the number of component attributes and their geographical distribution.

This project looks at practical approaches for the computer-aided analysis of current complex systems, with a focus on obtaining insight into their behavior.

Land Forces 2016: Claudia Szabo to discuss research ideas during Pitching Event

Claudia Szabo, the Complex Systems project leader will be pitching research ideas during the Land Forces 2016 conference. Come and find her to discuss ways of best modeling human interactions (both in person and online) in areas of conflict, to best identify emerging unwanted behaviors! The work builds on the group’s modeling of complex systems […]

PhD graduate recognised by Dean’s Commendation for Doctoral Thesis Excellence

Scott Bourne’s PhD thesis was recognised by Dean’s Commendation for Doctoral Thesis Excellence. Co-supervised by Prof. Michael Sheng and Dr Claudia Szabo, Scott’s PhD project focuses on developing novel solutions on formal validation of service-based business processes based on model checking techniques. The result has the potential to be applied in mission-critical applications (e.g., defence) […]

The best metrics for identifying self-organisation

Self-organisation is one of the key properties of complex systems yet automated tools to identify it have yet to be applied to systems other than toy models such as the Game of Life. Lachlan’s work is looking at implementing system complexity, Chan’s interaction metric, limited bandwidth recognition, de-centralised emergence detection and multi-scale Shannon entropy. His experiments […]

WSC 2016: CASL: A DECLARATIVE DOMAIN SPECIFIC LANGUAGE FOR MODELING COMPLEX ADAPTIVE SYSTEMS

Lachlan’s paper proposing a modeling language for complex adaptive systems has been accepted to WSC 2016! Abstract: Complex adaptive systems (CAS) are ubiquitous across many domains, such as social networks, supply chains, and smart cities. Currently, the modeling and analysis of CAS relies on adapting techniques used for multi-agent simulation, an approach which lacks several features […]
