Complex system From Wikipedia, the free encyclopedia Jump to: navigation search This article describes complex system as a type of system. For other meanings, see complex systems A complex system is a system composed of interconnected parts that as a whole exhibit one or more properties (behavior among the possible properties) not obvious from the properties of the individual parts. A system’s complexity may be of one of two forms: disorganized complexity and organized complexity In essence, disorganized complexity is a matter of a very large number of parts, and organized complexity is a matter of the subject system (quite possibly with only a limited number of parts) exhibiting emergent properties. Examples of complex systems include ant colonies ants themselves, human economies climate nervous systems ... cells and living things, including human beings, as well as modern energy or telecommunication infrastructures. Indeed, many systems of interest to humans are complex systems. Complex systems are studied by many areas of natural science mathematics , and social science . Fields that specialize in the interdisciplinary study of complex systems include systems theory complexity theory systems ecology , and cybernetics Contents Overview History Types of complex systems Chaotic systems ... edit Overview A complex system is any system featuring a large number of interacting components, whose aggregate activity is nonlinear and typically exhibits hierarchical self-organization under selective pressures.

Complex Systems Modeling: Using Metaphors From Nature in Simulation and Scientific Models Based on Rocha, Luis M. [1999]. BITS: Computer and Communications News . Computing, Information, and Communications Division. Los Alamos National Laboratory. November 1999. 1. What are complex systems? "A system comprised of a (usually large) number of (usually strongly) interacting entities, processes, or agents, the understanding of which requires the development, or the use of, new scientific tools, nonlinear models, out-of equilibrium descriptions and computer simulations ." [Advances in Complex Systems Journal] "A system that can be analyzed into many components having relatively many relations among them, so that the behavior of each component depends on the behavior of others. [Herbert Simon]" "A system that involves numerous interacting agents whose aggregate behaviors are to be understood. Such aggregate activity is nonlinear, hence it cannot simply be derived from summation of individual components behavior." [Jerome Singer] A complex system is any system featuring a large number of interacting components (agents, processes, etc.) whose aggregate activity is nonlinear (not derivable from the summations of the activity of individual components) and typically exhibits hierarchical self-organization under selective pressures. This definition applies to systems from a wide array of scientific disciplines. Indeed, the sciences of complexity are necessarily based on interdisplinary research. Not surprisingly, the heart of this research area is the

Home 21st Century Science Initiative Studying Complex Systems Studying Complex Systems The Complex Systems program supports scholarship and research directed toward the development of theoretical and mathematical tools that can be applied to the study of complex, adaptive, nonlinear systems. It is anticipated that research funded in this program will address issues in fields such as biology, biodiversity, climate, demography, epidemiology, technological change, economic development, governance, or computation. While the program's emphasis is on the development and application of theoretical models used in these research fields and not on particular fields per se, JSMF is particularly interested in projects attempting to apply complex systems approaches to meaningful problems. Proposals attempting to apply complex system tools and models to problems where such approaches are not yet considered usual or mainstream (for example, differentiating normal physiology from disease) are encouraged.

Introduction to Complex Systems by David Kirshbaum Outline of Contents I. Introduction: Complex Systems Theory : Basic Definition II. Four Important Characteristics of Complexity: Self-Organization Non-Linearity Order/Chaos Dynamic Emergent Properties III. Computer Programming approaches used for demonstrating, simulating, and analyzing these characteristics of Complex Systems: Artificial Life Genetic Algorithms Neural Networks Cellular Automata ... Boolean Networks I. Introduction to Complex Systems Theory : Basic Definition A Complex System is any system which involves a number of elements, arranged in structure(s) which can exist on many scales. These go through processes of change that are not describable by a single rule nor are reducible to only one level of explanation, these levels often include features whose emergence cannot be predicted from their current specifications. Complex Systems Theory also includes the study of the interactions of the many parts of the system. Previously, when studying a subject, researchers tended to use a reductionist approach which attempted to summarize the dynamics, processes, and change that occurred in terms of lowest common denominators and the simplest, yet most widely provable and applicable elegant explanations.

Physics of Complex Systems Physics of Complex Systems click here Nonequilibrium Statistical Physics and Self-Organization Quantum Information and Decoherence Networks: Social, Biological, and Technological ... Scaling, Universality, and Quantitative Laws of Life Nonequilibrium Statistical Physics and Self-Organization SFI Visiting Scientist Ole Peters and collaborators have argued that rainfall is an SOC phenomenon. Using satellite data from NASA’s Tropical Rainfall Measuring Mission, they present evidence that tropical convection and precipitation place the atmosphere near the critical point of a non-equilibrium phase transition between dry quiescence and strong deep convection with precipitation. Knowledge of the critical properties of this transition can help inform climate modeling by providing more realistic convective closure schemes, based on energy constraints and relations between atmospheric observables such as column-integrated water vapor and precipitation rate. As part of a larger project to understand how self-organized chemical states can be driven into existence by non-equilibrium energetic boundary conditions, SFI Professor Eric Smith has developed ensemble descriptions and entropy methods for driven quantum ensembles.  In particular, he has shown that maximization of the true entropy of a driven ensemble can lead to the spontaneous formation of stable currents, and that the entropy production principles of Onsager arise as context-dependent approximations if the equilibrium-form entropy instead of the exact entropy is used. Smith has also shown that the onset of order in thermodynamically

15. Complex Systems Research Lab While our main emphasis is aerospace systems and applications, our research results are applicable to complex systems in such domains as transportation, http://sunnyday.mit.edu/csrl.html

Complex Systems Research Lab The limits of what we can successfully build are changing from structural integrity and the physical limits of materials to the intellectual limits of those designing, operating, interacting with, and maintaining our engineered systems. New technology, particularly digital technology, is creating the potential for higher levels of integrated, multi-loop control in systems containing large numbers of dynamically interacting components (including humans). The result is that we are attempting to build systems where interactions among components cannot be thoroughly planned, understood, anticipated, or guarded against. The result has been " system accidents" and large-scale system failures, such as the recent Shuttle Columbia tragedy and the failure of the northeast power grid in August 2003. Increasing complexity and coupling as well as the introduction of new digital technology are making it difficult for designers to consider all potential system states and for operators to handle all normal and abnormal situations and disturbances safely and effectively. In CSRL we are designing system modeling, analysis, and visualization theory and tools to assist in the design and operation of safer systems with greater capability. To accomplish these goals, we apply a system's approach to engineering that includes building technical foundations and knowledge and integrating these with the organizational, political, and cultural aspects of system construction and operation.

Is the Complement System Irreducibly Complex? by Mike Coon [Last Update: April 4, 2002] "By irreducible complexity I mean a single system which is composed of several interacting parts that contribute to the basic function, and where the removal of any one of the parts causes the system to effectively cease functioning. An irreducibly complex system cannot be produced gradually by slight, successive modifications of a precursor system, since any precursor to an irreducibly complex system is by definition nonfunctional." Michael Behe his essay is intended to back up some elements of Keith Robison's excellent FAQ detailing the shortcomings of Behe's arguments ( http://www.talkorigins.org/faqs/behe/review.html ). Another excellent rebuttal by H. Allen Orr can be found at http://bostonreview.net/br21.6/orr.html . See also http://bostonreview.net/evolution.html for several articles on intelligent design and irreducible complexity by Orr, Russell F. Doolittle, Douglas J. Futuyma, Richard Dawkins, Michael Behe, Phillip Johnson and David Berlinski among others. Many people on Talk.Origins (T.O.) and elsewhere have outlined the conceptual reasons why Darwinian evolution can produce irreducibly complex (IC) systems. I try here to present some evidence to back up these concepts. In Robison's

Our experiences and observations strongly suggest Enterprise Engineering is best approached using CSE to engineer and manage the enterprise. The chapter is structured in four major sections: Why Rethink Systems Engineering? Complexity and Complex Systems Engineering Complex Systems Complex Systems Engineering in Practice We all must come to grips with the non-deterministic nature of enterprises. We hope to extend the concepts and methods of Systems Engineering to complex systems, and to open up the professional dialog so as to codify the engineering and management of complex systems and enterprises.
