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.
A causal loop diagram of growth and underinvestment. The growth and underinvestment archetype is one of the common system archetype patterns defined as part of the system dynamics discipline.
In business and IT development the term "systems modeling" has multiple meanings. It can relate to: the use of model to conceptualize and construct systems; the interdisciplinary study of the use of these models
The Social Construction of Reality: A Treatise in the Sociology of Knowledge (1966), by Peter L. Berger and Thomas Luckmann, proposes that social groups and individual persons who interact with each other, within a system of social classes, over time create concepts (mental representations) of the actions of each other, and that people become habituated to those concepts, and thus assume ...
Dynamical systems theory and chaos theory deal with the long-term qualitative behavior of dynamical systems.Here, the focus is not on finding precise solutions to the equations defining the dynamical system (which is often hopeless), but rather to answer questions like "Will the system settle down to a steady state in the long term, and if so, what are the possible steady states?", or "Does ...

The concept of a dynamical system has its origins in Newtonian mechanics.There, as in other natural sciences and engineering disciplines, the evolution rule of dynamical systems is an implicit relation that gives the state of the system for only a short time into the future.
Linear dynamical systems are dynamical systems whose evolution functions are linear.While dynamical systems, in general, do not have closed-form solutions, linear dynamical systems can be solved exactly, and they have a rich set of mathematical properties.
