System dynamics is a methodology and mathematical modeling technique to frame, understand, and discuss complex issues and problems. Originally developed in the 1950s to help corporate managers improve their understanding of industrial processes, SD is currently being used throughout the public and private sector for policy analysis and design.
STELLA (short for Systems Thinking, Experimental Learning Laboratory with Animation; also marketed as iThink) is a visual programming language for system dynamics modeling introduced by Barry Richmond in 1985. The program, distributed by isee systems (formerly High Performance Systems) allows users to run models created as graphical ...
Gerald Midgley pointed out that the structures of DSRP have analogues in other systems theories: distinctions are analogous to the boundaries of Werner Ulrich's boundary critique; Stafford Beer's viable system model explores nested systems (parts and wholes) in ways analogous to the "S" of DSRP; Jay Wright Forrester's system dynamics is an ...
the systems modeling, analysis, and design efforts; the systems modeling and simulation, such as system dynamics; any specific systems modeling language; As a field of study systems modeling has emerged with the development of system theory and systems sciences. As a type of modeling systems modeling is based on systems thinking and the systems ...
Modelica is an object-oriented, declarative, multi-domain modeling language for component-oriented modeling of complex systems. Next to the free System Dynamics library, which is exclusively based on modeling signal flows, there is a free Business Simulation Library (BSL) dedicated to System Dynamics, which makes use of Modelica's acausal ...
Critical systems thinking, including the E P I C approach. Ontology engineering of representation, formal naming and definition of categories, and the properties and the relations between concepts, data, and entities. Soft systems methodology, including the CATWOE approach and rich pictures. Systemic design, for example using the double diamond ...
Barry Marshall Richmond (14 November 1946 – 3 August 2002) was an American systems scientist, and former managing director of High Performance Systems, Inc (HPS), an organization providing software and consulting services to build the capacity of people to understand and improve the workings of dynamic systems.
