What is Complex Systems

1.

are said to be systems of interacting components with no central control that display emergent global properties not present at the components level. Learn more in: A Model for a Heterogeneous Genetic Network

2.

Systems that interweave components in such a way that they display variation without being random, and result in a structure that is more than the sum of its parts. Learn more in: Exploring Information Security Risks in Healthcare Systems

3.

A system made up of a number of connected objects, which shows a number of properties which include nonlinearity, emergence and interactions – often these systems are referred to as complex adaptive systems. Learn more in: Multi-Scale, Multi-Dimensional Modelling of Future Energy Systems

4.

Complex Systems is a new field of science studying how parts of a complex system give rise to the collective behaviors of the system. Complexity (information-theoretical and computational) and emergence of collective behavior are the two main characteristics of such complex systems. Social systems formed (in part) out of people, the brain formed out of neurons, molecules formed out of atoms, the weather formed out of air flows are all examples of complex systems. The field of Complex Systems cuts across all traditional disciplines of science, as well as engineering, management, and medicine. Learn more in: Querical Data Networks

5.

Refer to systems that are composed of a (large) number of parts that interact in a non-simple way and where the whole is more than the sum of the parts, and that does not have pure superposition of phenomena and processes. Learn more in: An Agent-Based Approach to Designing VO

6.

Network-based systems characterized by feedback-driven flow of information, openness, self-organization, and emergence. Learn more in: Measures of Network Structure

7.

An organizational system in which agents act locally with each other based on an identity that has developed historically; they do this without knowing how the whole system will develop further and without an understanding of the current state of the system as a whole.

8.

Systems made of several interconnected simple parts which altogether exhibit a high degree of complexity from each emerges a higher order behaviour. Learn more in: Mathematical Modeling of Artificial Neural Networks
