Symmetry in Complex Systems

Requirements Engineering Model in Designing Complex Systems

This research tends to development of the requirements elicitation methodology with regard to operational nature and hierarchical analysis for complex systems and also, regarding available technologies. This methodology applies Analytic Hierarchy Process (AHP) and Analytic Network Process (ANP) to ensure traceability of planned qualitative and quantitative data from requirements to available te...

Symmetry in Complex Networks

In this paper, we analyze a few interrelated concepts about graphs, such as their degree, entropy, or their symmetry/asymmetry levels. These concepts prove useful in the study of different types of Systems, and particularly, in the analysis of Complex Networks. A System can be defined as any set of components functioning together as a whole. A systemic point of view allows us to isolate a part ...

Symmetry in complex networks

We consider the size and structure of the automorphism groups of a variety of empirical ‘realworld’ networks and find that, in contrast to classical random graph models, many real-world networks – including a variety of biological networks and technological networks such as the internet – are richly symmetric. We then discuss how knowledge of the structure of the automorphism group of a network...
