What is Simulation? What is Modelling?
The terms “modelling” and “simulation” are sometimes used interchangeably. In reality, they
are distinct, though related, terms.
‘Modelling’ is the representation of an object or phenomena, which is used by simulation.
Models may be mathematical, physical, or logical representations of a system, entity,
phenomenon, or process. Models are, in turn, used by simulation to predict a future state.
Examples of models:
*Mathematical model of sensor response.
*Computer aided design model of an armoured vehicle or a helicopter or a human being
It refers to the process of creating models.
‘Simulation’ is a representation of the functioning of a system or process. Through
simulation, a model may be implanted with unlimited variations, producing complex
scenarios. These capabilities allow analysis and understanding of how individual elements
interact and affect the simulated environment.
Example of a simulation:
*three-dimensional model of an armoured vehicle which moves across a model of terrain
over time.
The tool that executes the simulation is a "simulator".
Live Simulations - Real people operate in the real world.
Virtual Simulations - Real people operate in synthetic worlds.
Constructive Simulations - Simulated entities operate in synthetic worlds.
Undefined Simulations - Simulated entities are subjected to real world environments.
Applications of Simulation: Experimentation, Operational Planning, Training, Missions
Rehearsal, Support to the Conduct of Operations, Life Cycle Management.
Generally, people most readily associate Modelling and Simulation (M&S) with training.
M&S tools are used to train astronauts, commercial and military aircrews, nuclear power
specialists, healthcare workers, and maintenance specialists, just to name a few professionals.
M&S provides rehearsal environments for civilian first responder and military personnel.
Repeated rehearsal of procedures improves performance, saving countless lives as well as
aircraft, ships, and other vehicles. Also, training individuals before allowing them to use
actual equipment improves the safety of the individuals undergoing training, the participants
around them and the safety of the actual equipment.
Learning Simulation:
The initial design basis for all training/learning involving any use of a simulation is instructional
design. The process does not begin with the technology, although sometimes it is hard to convince
clients that the technology to be used is not the beginning point. In the past sixty years there have
