Scienza dei sistemi
........La pagina tradotta completamente in Italiano sarà disponibile a partire dal 11 Agosto 2016.......
Scienza dei Sistemi - sistemologia (greco. σύστημα - systema, λόγος - logos) o teoria dei sistemi é un campo di ricerca interdisciplinare che studia la natura dei sistemi (dal semplice al complesso) in natura, negli ambiti sociali a nella scienza stessa. Questo campo di ricerca tende a sviluppare le fondazioni interdisciplinari che siano applicabili in varie aree, come l'ingegneria, la biologia, la medicina e le scienze sociali. [1]
La Scienza dei sistemi comprende scienze formali quali: scienza dei sistemi complessi, cibernetica, teoria della dinamica dei sistemi, teoria dei sistemi e applicazioni nel campo delle scienze naturali e sociali ed nell'ingegneria, come: teoria del controllo, ricerca operazionale, teoria dei sistemi sociali, biologia sistemica, dinamica dei sistemi, fattori umani, ecologia sistemica, ingegneria sistemica e psicologia sistemica.[2] I temi normalmente evidenziati nella scienza sistemica sono (a) il punto di vista olistico, (b) l'interazione tra il sistema e l'ambiente in cui é inserito, e (c) i percorsi complessi (o indiretti) della dinamica del sistema che alcune volte sono stabili (e quindi che si rinforzano), mentre in diverse 'condizioni limite' possono diventare molto instabili (e quindi distruttivi). Interrogativi sulle dinamiche a livello planetario (Terrestre) della biosfera/geosfera sono un esempio dei tipi di problemi a cui la scienza dei sistemi cerca di dare significativi contributi.
Teorie
Fin dalla nascita della ricerca sui sistemi generici (general systems research) negli anni 50 del XX secolo,[3] il pensiero sistemico e la scienza dei sistemi si sono sviluppate in molti quadri teorici.
- Analisi dei sistemi
- Systems analysis is the branch of systems science that analyzes systems, the interactions within those systems, and/or interaction with its environment,[4] often prior to their automation as computer models. This field is closely related to operations research.
- Design (Ideazione) dei sistemi
- Systems design is the process of "establishing and specifying the optimum system component configuration for achieving specific goal or objective."[4] For example in computing, systems design can define the hardware and systems architecture which includes many sub-architectures including software architecture, components, modules, interfaces, and data, as well as security, information, and others, for a computer system to satisfy specified requirements.
- Dinamica dei sistemi
- System dynamics is an approach to understanding the behavior of complex systems over time. It offers "simulation technique for modeling business and social systems,"[5] which deals with internal feedback loops and time delays that affect the behavior of the entire system. What makes using system dynamics different from other approaches to studying complex systems is the use of feedback loops and stocks and flows.
- Ingegneria dei sistemi
- Systems engineering (SE) is an interdisciplinary field of engineering, that focuses on the development and organization of complex systems. It is the "art and science of creating whole solutions to complex problems,"[6] for example: signal processing systems, control systems and communication system, or other forms of high-level modelling and design in specific fields of engineering.
- Metodologie sistemiche
- There are several types of Systems Methodologies, that is, disciplines for analysis of systems. For example:
- Soft systems methodology (SSM) : in the field of organizational studies is an approach to organisational process modelling, and it can be used both for general problem solving and in the management of change. It was developed in England by academics at the University of Lancaster Systems Department through a ten-year Action Research programme.
- System development methodology (SDM) in the field of IT development is a general term applied to a variety of structured, organized processes for developing information technology and embedded software systems.
- Viable systems approach (vSa) is a methodology useful for the understanding and governance of complex phenomena; it has been successfully proposed in the field of management, decision making, marketing and service.
- Teoria dei sistemi
- Systems theory is an interdisciplinary field that studies complex systems in nature, society, and science. More specifically, it is a conceptual framework by which one can analyze and/or describe any group of objects that work in concert to produce some result.
- Scienze sistemiche
- Systems sciences are scientific disciplines partly based on systems thinking such as chaos theory, complex systems, control theory, cybernetics, sociotechnical systems theory, systems biology, systems ecology, systems psychology and the already mentioned systems dynamics, systems engineering, and systems theory.
Campi di indagine scientifica
Systems sciences cover formal sciences like dynamical systems theory and applications in the natural and social sciences and engineering, such as social systems theory and systems dynamics.
Ricercatori nel campo della scienza dei sistemi
General systems scientists can be divided into different generations. The founders of the systems movement like Ludwig von Bertalanffy, Kenneth Boulding, Ralph Gerard, James Grier Miller, George J. Klir, and Anatol Rapoport were all born between 1900 and 1920. They all came from different natural and social science disciplines and joined forces in the 1950s to establish the general systems theory paradigm. Along with the organization of their efforts a first generation of systems scientists rose.
Among them were other scientists like Ackoff, Ashby, Margaret Mead and Churchman, who popularized the systems concept in the 1950s and 1960s. These scientists inspired and educated a second generation with more notable scientists like Ervin Laszlo (1932) and Fritjof Capra (1939), who wrote about systems theory in the 1970s and 1980s. Others got acquainted and started studying these works in the 1980s and started writing about it since the 1990s. Debora Hammond can be seen as a typical representative of these third generation of general systems scientists.
Organizzazioni
The International Society for the Systems Sciences (ISSS) is an organisation for interdisciplinary collaboration and synthesis of systems sciences. The ISSS is unique among systems-oriented institutions in terms of the breadth of its scope, bringing together scholars and practitioners from academic, business, government, and non-profit organizations. Based on fifty years of tremendous interdisciplinary research from the scientific study of complex systems to interactive approaches in management and community development. This society was initially conceived in 1954 at the Stanford Center for Advanced Study in the Behavioral Sciences by Ludwig von Bertalanffy, Kenneth Boulding, Ralph Gerard, and Anatol Rapoport.
In the field of systems science the International Federation for Systems Research (IFSR) is an international federation for global and local societies in the field of systems science. This federation is a non-profit, scientific and educational agency founded in 1981, and constituted of some thirty member organizations from various countries. The overall purpose of this Federation is to advance cybernetic and systems research and systems applications and to serve the international systems community.
The best known research institute in the field is the Santa Fe Institute (SFI) located in Santa Fe, New Mexico, United States, dedicated to the study of complex systems. This institute was founded in 1984 by George Cowan, David Pines, Stirling Colgate, Murray Gell-Mann, Nick Metropolis, Herb Anderson, Peter A. Carruthers, and Richard Slansky. All but Pines and Gell-Mann were scientists with Los Alamos National Laboratory. SFI's original mission was to disseminate the notion of a separate interdisciplinary research area, complexity theory referred to at SFI as complexity science.
