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.
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.
Instructional simulation. An instructional simulation, also called an educational simulation, is a simulation of some type of reality (system or environment) but which also includes instructional elements that help a learner explore, navigate or obtain more information about that system or environment that cannot generally be acquired from mere ...
A computer lab with desktop PCs with flat-panel monitors. A desktop computer (often abbreviated desktop[ 1]) is a personal computer designed for regular use at a stationary location on or near a desk (as opposed to a portable computer) due to its size and power requirements. The most common configuration has a case that houses the power supply ...
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 ...
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.
Computer memory stores information, such as data and programs, for immediate use in the computer. [ 2] The term memory is often synonymous with the terms RAM, main memory, or primary storage. Archaic synonyms for main memory include core (for magnetic core memory) and store. [ 3]
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 ...
