What Makes Complex Systems Complex?

Russ Abbott
2018 Journal on Policy and Complex Systems  
This paper explores some of the factors that make complex systems complex. We first examine the history of complex systems.  ...  We find (a) that scientific reductionism does not provide a sufficient explanation; (b) that to understand complex systems, one must identify and trace energy flows; and (c) that disproportionate causality  ...  Summary S o, why are complex systems complex?  ...

On a maturity model for complexity, complex systems, and complex systems engineering

B.E. White
2016 International Journal of Design & Nature and Ecodynamics  
Complexity, complex systems, complex systems engineering, and other related terms are defined.  ...  An initial draft maturity model is offered that includes examples of complexity, a collection of complex system characteristics, behaviors, and problems; a set of complex systems engineering principles  ...  Examples of complex systems problems In Since people are complex, systems that include them are also complex.  ...

Health Systems as Complex Systems

Mireya Martínez-García, Enrique Hernández-Lemus
2013 American Journal of Operations Research  
However, recent developments in the sciences of complexity point out to health systems as complex entities governed by non-linear interaction laws, self-organization and emergent phenomena.  ...  In this work we review some aspects of complexity behind health systems and how they can be applied to improve the performance of healthcare organizations.  ...  Recognizing health systems as complex systems is just the beginning.  ...

Understanding Complex Systems [chapter]

Paul Cilliers
2012 Handbook of Systems and Complexity in Health  
Paul Cilliers contributes to our general understanding of complex systems, and explores the implications of complexity theory for our understanding of biological and social systems.  ...  Cilliers points out that this approach to complexity leads to models of complex systems that avoid the oversimplification that results from rulebased models.  ...  Models of complex systems will have to be as complex as the systems themselves.  ...

Complex Gradient Systems [article]

Giuseppe Tomassini, Sergio Venturini
2011 arXiv   pre-print
Let M be a complex manifold of complex dimension n+k. We say that the functions u_1,...s,u_k and the vector fields ξ_1,...,ξ_k on M form a complex gradient system if ξ_1,...,ξ_k,Jξ_1,...  ...  We prove a Cauchy theorem for such complex gradient systems with initial data along a -submanifold of type (,).  ...  We associate to F a complex gradient system as follows. Set M = Ω × C k , V = R k and define  ...
