This document defines computer simulation as imitating real things, states, or processes and key characteristics of selected physical or abstract systems. It discusses categories of simulation based on application area and functionality. Simulation is needed for complex models with nonlinear variable relationships or random variables. Simulations provide graphical screens, simulators, and 3D graphics. They have applications in advanced analytics, airports, manufacturing, space, healthcare, military, and mining. Advantages include studying systems without building them and performing "what if" analysis, while disadvantages include costs and difficulty interpreting results.

3. Definition
Simulation is the imitation of
 Some real thing
 State of affairs or
 Process
It also involves certain key characteristics of
Selected physical or abstract system.

4. Categories of Simulation
 On the basis of the application area
 On the basis of the functionality of the
software/simulation
 On the basis of overarching capabilities.

5. Need of simulation
 Simulation is needed in the following
cases:
 the model is very complex
 the underlying variables relationships are
nonlinear.
 the model contains random variates
 the model output is to be visual as in a 3D
computer animation.

6. Simulation provide
 Graphical screen
 Simulators
 3D graphics

7. Applications of simulations
 Advanced Analytics
 Airports
 Manufacturing
 In space
 Healthcare
 Military
 Mining

11. Advantages
 Study the behavior of a system without
building it.
 Results are accurate in general, compared
to analytical model.
 Help to find un-expected phenomenon,
behavior of the system.
 Easy to perform ``What-If'' analysis.
disadvantages
 Expensive to build a simulation model.
 to conduct simulation.
 Sometimes it is difficult to interpret the
simulation results
