Dynamic stock and flow diagram of model New product adoption (model from article by John Sterman 2001 - True Software). System dynamics (SD) is an approach to understanding the nonlinear behaviour of complex systems over time using stocks, flows, internal feedback loops, table functions and time delays.
Dynamical system simulation or dynamic system simulation is the use of a computer program to model the time-varying behavior of a dynamical system. The systems are typically described by ordinary differential equations or partial differential equations .
Dynamic documentation is a feature: As the model evolves the documentation must evolve as well. The application should allow the business analyst to document at service level and then generate a cohesive document that encompasses entire model. Business Analyst Interface is friendly and flexible:
Dynamic programming is both a mathematical optimization method and an algorithmic paradigm. The method was developed by Richard Bellman in the 1950s and has found applications in numerous fields, from aerospace engineering to economics .
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.
A dynamic mathematical model in this context is a mathematical description of the dynamic behavior of a system or process in either the time or frequency domain. Examples include: Examples include: physical processes such as the movement of a falling body under the influence of gravity ;
Static vs. dynamic. A dynamic model accounts for time-dependent changes in the state of the system, while a static (or steady-state) model calculates the system in equilibrium, and thus is time-invariant. Dynamic models typically are represented by differential equations or difference equations. Explicit vs. implicit.
Object model: The object model represents the static and most stable phenomena in the modeled domain. [3] Main concepts are classes and associations with attributes and operations. Aggregation and generalization (with multiple inheritance) are predefined relationships. [2] Dynamic model: The dynamic model represents a state/transition view on ...
