SIMULATORS

 

Definitions

Simulation: is an imitation of some real device or state of affairs. Simulation attempts to represent certain features of the behavior of a physical or abstract system by the behavior of another system. Simulation is used in many contexts, including the modeling of natural systems, and human systems to gain insight into the operation of those systems;

 

Physical Simulation: refers to simulation in which physical objects are substituted for the real thing; these physical objects are often chosen because they are smaller or cheaper, than the actual object or system.

 

Computer Simulation (Computer Model): is a computer program which attempts to simulate an abstract model of a particular system. Computer simulations have become a useful part of modeling many natural systems in physics, chemistry and biology, human systems in economics and social science and in the process of engineering new technology, to gain insight into the operation of those systems. Computer models can be classified according to several criteria including: Stochastic or deterministic; continuous or discrete; local or distributed. Computer simulations are often considered human out of the loop simulations.

 

Interactive Simulation: is a special kind of physical simulation, and often referred to as human in the loop simulations, is physical simulations that include humans, such as the model used in a flight simulator.

 

Live Simulation: where real people use simulated (or "dummy") equipment in the real world.

 

Virtual Simulation: where real people use simulated equipment in a simulated world (or "virtual environment")

 

Constructive Simulation: where simulated people use simulated equipment in a simulated environment. Constructive simulation is often referred to as "war gaming" since it bears some resemblance to table-top war games in which players command armies of soldiers and equipment which move around a board.

 

Simulator: a machine that simulates an environment for the purpose of training or research. Some of the simulator types are: Computer Aided Trainer (CAT), Computer Based Trainer (CBT), Cockpit Procedure Trainer (CPT), Full Mission Simulator (FMS), Part Task Trainer (PTT), Weapons Systems Trainer (WST), Tactical Control Center (TCC), Research Simulators.
