Systemography
Systemography or SGR is a process where phenomena regarded as complex are purposefully represented as a constructed model of a general system. It may be used in three different ways: conceptualization, analysis, and simulation. The work of Jean-Louis Le Moigne is associated with systemography. Systemography modeling consists of building, simultaneously, the process' operational, informational and decisional systemographs in modeling phase. Ettore Bresciani Filho (2001) recommends the following order in systemography modeling: #Define the border of the system to be modeled, characterizing the border's processors responsible for the system's inputs and outputs. #Build the operational systemograph of the production system, disposing in a block diagram the production process' different stages, representing each with an operational processor. #Build the informational systemograph of the production system, disposing in a block diagram the different stages of the information's generati ...

Systems Theory
Systems theory is the interdisciplinary study of systems, i.e. cohesive groups of interrelated, interdependent components that can be natural or human-made. Every system has causal boundaries, is influenced by its context, defined by its structure, function and role, and expressed through its relations with other systems. A system is "more than the sum of its parts" by expressing synergy or emergent behavior. Changing one component of a system may affect other components or the whole system. It may be possible to predict these changes in patterns of behavior. For systems that learn and adapt, the growth and the degree of adaptation depend upon how well the system is engaged with its environment and other contexts influencing its organization. Some systems support other systems, maintaining the other system to prevent failure. The goals of systems theory are to model a system's dynamics, constraints, conditions, and relations; and to elucidate principles (such as purpose, measure ...

List Of Types Of Systems Theory
This list of types of systems theory gives an overview of different types of systems theory, which are mentioned in scientific book titles or articles. The following more than 40 types of systems theory are all explicitly named ''systems theory'' and represent a unique conceptual framework in a specific field of science. Systems theory has been formalized since the 1950s, and a long set of specialized systems theories and cybernetics exist. In the beginnings, general systems theory was developed by Ludwig von Bertalanffy to overcome the over-specialisation of the modern times and as a worldview using holism. The systems theories nowadays are closer to the traditional specialisation than to holism, by interdependencies and mutual division by mutually-different specialists. __NOTOC__ A * Abstract systems theory (also see: formal system) * Action Theory * Adaptive systems theory (also see: complex adaptive system) * Applied general systems theory (also see: general systems theor ...

Systemics
In the context of systems science and systems philosophy, systemics is an initiative to study systems. It is an attempt at developing logical, mathematical, engineering and philosophical paradigms and frameworks in which physical, technological, biological, social, cognitive and metaphysical systems can be studied and modeled. The term "systemics" was coined in the 1970s by Mario Bunge and others, as an alternative paradigm for research related to general systems theory and systems science.Mario Bunge (1979).

Social Complexity
In sociology, social complexity is a conceptual framework used in the analysis of society. In the sciences, contemporary definitions of complexity are found in systems theory, wherein the phenomenon being studied has many parts and many possible arrangements of the parts; simultaneously, what is complex and what is simple are relative and change in time. Contemporary usage of the term ''complexity'' specifically refers to sociologic theories of society as a complex adaptive system, however, social complexity and its emergent properties are recurring subjects throughout the historical development of social philosophy and the study of social change.Eve, Raymond, Sara Horsfall and Mary E. Lee (eds.) (1997). ''Chaos, Complexity and Sociology: Myths, Models, and Theories.'' Thousand Oaks, CA: Sage Publications. Early theoreticians of sociology, such as Ferdinand Tönnies, Émile Durkheim, and Max Weber, Vilfredo Pareto and Georg Simmel, examined the exponential growth and interrela ...

Open And Closed Systems In Social Science
Ludwig Bertalanffy describes two types of systems: open systems and closed systems. The open systems that we know of are systems that allow interactions between their internal elements and the environment. An open system is defined as a “system in exchange of matter with its environment, presenting import and export, building-up and breaking-down of its material components.” Closed systems, on the other hand, are held to be isolated from their environment. Equilibrium thermodynamics, for example, is a field of study that applies to closed systems. The idea of open systems was further developed in systems theory. Social science In social sciences, schematically, if there is an interaction or feedback loop between ideal and material or subjective and objective then the system is an open system, otherwise it is a closed system. A closed system offers a deterministic relationship. René Descartes’ view of a subject as a determining agent, detached from nature, is a closed syst ...

World-systems Theory
World-systems theory (also known as world-systems analysis or the world-systems perspective)Immanuel Wallerstein, (2004), "World-systems Analysis." In ''World System History'', ed. George Modelski, in ''Encyclopedia of Life Support Systems'' (EOLSS), Developed under the Auspices of the UNESCO, Eolss Publishers, Oxford, UK is a multidisciplinary approach to world history and social change which emphasizes the world-system (and not nation states) as the primary (but not exclusive) unit of social analysis. "World-system" refers to the inter-regional and transnational division of labor, which divides the world into core countries, semi-periphery countries, and the periphery countries. Core countries focus on higher-skill, capital-intensive production, and the rest of the world focuses on low-skill, labor-intensive production and extraction of raw materials. This constantly reinforces the dominance of the core countries. Nonetheless, the system has dynamic characteristics, in part a ...

Systemantics
''General Systemantics'' (retitled to ''Systemantics'' in its second edition and ''The Systems Bible'' in its third) is a systems engineering treatise by John Gall in which he offers practical principles of systems design based on experience and anecdotes. It is offered from the perspective of how ''not'' to design systems, based on system engineering failures. The primary precept of the treatise is that large complex systems are extremely difficult to design correctly despite best intentions, so care must be taken to design smaller, less-complex systems and to do so with incremental functionality based on close and continual touch with user needs and measures of effectiveness. Title origin The term systemantics is a commentary on prior work by Alfred Korzybski called General Semantics which conjectured that all systems failures could be attributed to a single root cause—a failure to communicate. Dr. Gall observes that, instead, system failure is an ''intrinsic feature o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Systems Theory In Political Science
Systems theory in political science is a highly abstract, partly holistic view of politics, influenced by cybernetics. The adaptation of system theory to political science was conceived by David Easton in 1953. Overview In simple terms, Easton's behavioral approach to politics, proposed that a political system could be seen as a delimited (i.e. all political systems have precise boundaries) and fluid (changing) system of steps in decision making. Greatly simplifying his model: Influence of computers on the discipline of political science and the political system work within an environment. The environment generates different demands from different section of society such as reservation system in the matter of a certain group, demand for better transportation etc. * Step 1. changes in the social or physical environment surrounding a political system produce "demands" and "supports" for action or the status quo directed as "inputs" towards the political system, through political behav ...

Systems Theory In Archaeology
Systems theory in archaeology is the application of systems theory and systems thinking in archaeology. It originated with the work of Ludwig von Bertalanffy in the 1950s, and is introduced in archaeology in the 1960s with the work of Sally R. Binford & Lewis Binford's "New Perspectives in Archaeology" and Kent V. Flannery's "Archaeological Systems Theory and Early Mesoamerica". Overview Bertalanffy attempted to construct a general systems theory that would explain the interactions of different variables in a variety of systems, no matter what those variables actually represented. A system was defined as a group of interacting parts and the relative influence of these parts followed rules which, once formulated could be used to describe the system no matter what the actual components were. Binford stated the problem in ''New Perspectives in Archaeology'', identifying the low range theory, the middle range theory, and the upper range theory. * The low range theory could be us ...

Systems Theory In Anthropology
Systems theory in anthropology is an interdisciplinary, non-representative, non-referential, and non-Cartesian approach that brings together natural and social sciences to understand society in its complexity. The basic idea of a system theory in social science is to solve the classical problem of duality; mind-body, subject-object, form-content, signifier-signified, and structure-agency. System theory suggests that instead of creating closed categories into binaries (subject-object); the system should stay open so as to allow free flow of process and interactions. In this way the binaries are dissolved. Complex systems in nature—for example, ecosystems—involve a dynamic interaction of many variables (e.g. animals, plants, insects and bacteria; predators and prey; climate, the seasons and the weather, etc.) These interactions can adapt to changing conditions but maintain a balance both between the various parts and as a whole; this balance is maintained through homeostasis. ...

Systems Psychology
Systems psychology is a branch of both theoretical psychology and applied psychology that studies human behaviour and experience as complex systems. It is inspired by systems theory and systems thinking, and based on the theoretical work of Roger Barker, Gregory Bateson, Humberto Maturana and others. Groups and individuals are considered as systems in homeostasis. Alternative terms here are "systemic psychology", "systems behavior", and "systems-based psychology". Types In the scientific literature, different kinds of systems psychology have been mentioned: ;Applied systems psychology :In the 1970s the term applied systems psychology was being used as a specialism directly related to engineering psychology and human factor. ;Cognitive systems theory :Cognitive systems psychology is a part of cognitive psychology and like existential psychology, attempts to dissolve the barrier between conscious and the unconscious mind. ;Concrete systems psychology :Concrete systems ps ...

Systems Engineering
Systems engineering is an interdisciplinary field of engineering and engineering management that focuses on how to design, integrate, and manage complex systems over their enterprise life cycle, life cycles. At its core, systems engineering utilizes systems thinking principles to organize this body of knowledge. The individual outcome of such efforts, an engineered system, can be defined as a combination of components that work in synergy to collectively perform a useful Function (engineering), function. Issues such as requirements engineering, reliability, logistics, coordination of different teams, testing and evaluation, maintainability and many other Discipline (academia), disciplines necessary for successful system design, development, implementation, and ultimate decommission become more difficult when dealing with large or complex projects. Systems engineering deals with work-processes, optimization methods, and risk management tools in such projects. It overlaps technical ...
