  2. System dynamics - Wikipedia

    en.wikipedia.org/wiki/System_dynamics

    Computer software is used to simulate a system dynamics model of the situation being studied. Running "what if" simulations to test certain policies on such a model can greatly aid in understanding how the system changes over time. System dynamics is very similar to systems thinking and constructs the same causal loop diagrams of systems with ...

    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 ...

    en.wikipedia.org/wiki/STELLA_(programming_language)

    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 ...

  7. Systems engineering - Wikipedia

    en.wikipedia.org/wiki/Systems_engineering

    Systems engineering techniques are used in complex projects: printed-circuit-board design, robotics, bridge building, software integration, and spacecraft design. Systems engineering uses a host of tools that include modeling and simulation, requirements analysis, and scheduling to manage complexity.

  8. Systems theory - Wikipedia

    en.wikipedia.org/wiki/Systems_theory

    The goals of systems theory are to model a system's dynamics, constraints, conditions, and relations; and to elucidate principles (such as purpose, measure, methods, tools) that can be discerned and applied to other systems at every level of nesting, and in a wide range of fields for achieving optimized equifinality. [3]

  9. Model-based systems engineering - Wikipedia

    en.wikipedia.org/.../Model-based_systems_engineering

    The first known prominent public usage of the term "Model-Based Systems Engineering" is a book by A. Wayne Wymore with the same name. [8] The MBSE term was also commonly used among the SysML Partners consortium during the formative years of their Systems Modeling Language (SysML) open source specification project during 2003-2005, so they could distinguish SysML from its parent language UML v2 ...
