The Collaborative International Dictionary

Simulation \Sim`u*la"tion\, n. [F. simulation, L. simulatio.] The act of simulating, or assuming an appearance which is feigned, or not true; -- distinguished from dissimulation, which disguises or conceals what is true.

Syn: Counterfeiting; feint; pretense.

Douglas Harper's Etymology Dictionary

mid-14c., "a false show, false profession," from Old French simulation "pretence" and directly from Latin simulationem (nominative simulatio) "an imitating, feigning, false show, hypocrisy," noun of action from past participle stem of simulare "imitate," from stem of similis "like" (see similar). Meaning "a model or mock-up for purposes of experiment or training" is from 1954.


n. 1 Something which simulates a system or environment in order to predict actual behaviour.'' 2 The process of simulating. 3 Assuming an appearance which is feigned, or not true. 4 (context soccer English) The act of fall over in order to be awarded a foul, when a foul hasn't been committed.

  1. n. (computer science) the technique of representing the real world by a computer program; "a simulation should imitate the internal processes and not merely the results of the thing being simulated" [syn: computer simulation]

  2. the act of imitating the behavior of some situation or some process by means of something suitably analogous (especially for the purpose of study or personnel training)

  3. representation of something (sometimes on a smaller scale) [syn: model]

  4. the act of giving a false appearance; "his conformity was only pretending" [syn: pretense, pretence, pretending, feigning]

Simulation (journal)

Simulation is a peer-reviewed academic journal that publishes papers in the field of computer Science. The journal's editor is Levent Yilmaz ( Auburn University). It has been in publication since 1963 and is currently published by SAGE Publications in association with Society for Modeling and Simulation International.


Simulation is the imitation of the operation of a real-world process or system over time. The act of simulating something first requires that a model be developed; this model represents the key characteristics or behaviors/ functions of the selected physical or abstract system or process. The model represents the system itself, whereas the simulation represents the operation of the system over time.

Simulation is used in many contexts, such as simulation of technology for performance optimization, safety engineering, testing, training, education, and video games. Often, computer experiments are used to study simulation models. Simulation is also used with scientific modelling of natural systems or human systems to gain insight into their functioning. Simulation can be used to show the eventual real effects of alternative conditions and courses of action. Simulation is also used when the real system cannot be engaged, because it may not be accessible, or it may be dangerous or unacceptable to engage, or it is being designed but not yet built, or it may simply not exist.

Key issues in simulation include acquisition of valid source information about the relevant selection of key characteristics and behaviours, the use of simplifying approximations and assumptions within the simulation, and fidelity and validity of the simulation outcomes. Procedures and protocols for model verification and validation are an ongoing field of academic study, refinement, research and development in simulations technology or practice, particularly in the field of computer simulation.
