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 systems modeling, analysis, and design efforts. the systems modeling and simulation, such as system dynamics.
A von Neumann architecture scheme. The von Neumann architecture —also known as the von Neumann model or Princeton architecture —is a computer architecture based on a 1945 description by John von Neumann, and by others, in the First Draft of a Report on the EDVAC. [ 1 ] The document describes a design architecture for an electronic digital ...
The systems modeling language ( SysML) [ 1] is a general-purpose modeling language for systems engineering applications. It supports the specification, analysis, design, verification and validation of a broad range of systems and systems-of-systems . SysML was originally developed by an open source specification project, and includes an open ...
A system architecture primarily concentrates on the internal interfaces among the system's components or subsystems, and on the interface (s) between the system and its external environment, especially the user. (In the specific case of computer systems, this latter, special, interface is known as the computer human interface, AKA human ...
Computer simulation. Computer simulation is the process of mathematical modelling, performed on a computer, which is designed to predict the behaviour of, or the outcome of, a real-world or physical system. The reliability of some mathematical models can be determined by comparing their results to the real-world outcomes they aim to predict.
Function model. In systems engineering, software engineering, and computer science, a function model or functional model is a structured representation of the functions ( activities, actions, processes, operations) within the modeled system or subject area. [ 1]
e. System identification methods.png. The field of system identification uses statistical methods to build mathematical models of dynamical systems from measured data. [ 1] System identification also includes the optimal design of experiments for efficiently generating informative data for fitting such models as well as model reduction.
Computational model. A computational model uses computer programs to simulate and study complex systems [ 1] using an algorithmic or mechanistic approach and is widely used in a diverse range of fields spanning from physics, [ 2] engineering, [ 3] chemistry [ 4] and biology [ 5] to economics, psychology, cognitive science and computer science.
