4. What is Computer Simulation?
4
Computer simulation is :
 The process to create an imitation of real world
system or physical object into a computer model.
 Performing experiments to understand the
behavior of system and evaluating new
strategies.
 Then observing events, processes, properties
and behavior of system, with computer model.

 Computer simulation of weather forecasting can
be used to predict storms
 The wind, rain pattern and temperatures e.t.c for
the whole planet are simulated using very
powerful computers.

 Simulations software are used to design safer
cars and improve their designs ( performing real
car crash just to check design stability is very
expensive)

 Simulations software are used to design safer

 Design of ships are also simulated first to achieve
more perfection

15. Architecture

 Design stability of buildings are checked by
simulation of earth quake through simulation
software
 Bridges are also simulated to check how much
load they can resist, and what improvement can
be made

18. Aeronautics
18
 Trainee pilots have many hours of lesson in flight
simulators before being allowed to fly an
airplanes.
 These simulators provide realistic flying situation
like storms, engine failure…
 This experience help them to tackle such
situation in real, as they have gained a bit
experience.

Simulation

22. Advantages of Computer
Simulation
22
 To test a system without having to create the system
for real (Building real-life systems can be expensive,
and take a long time)
 To predict what might happen to a system in the
future (An accurate model allows us to go forward in
virtual time to see what the system will be doing in the
future)
 To train people to use a system without putting them
at risk (Learning to fly an airplane is very difficult and
mistake will be made. In a real plane mistakes could
be fatal!)
 To investigate a system in great detail (A model of a
system can be zoomed in/out or rotated. Time can be
stopped, rewound, etc.)

23. Disadvantages of Computer
Simulation
23
 It depends upon the skills of the model maker
 Time consuming and high cost
 Sometimes, it does not give the best solution for
system

24. Conclusion
24
 Computer Simulation and Modeling software are
very useful in many areas.
 It gives great understanding of a system and also
predicts the behavior of system in different
situation
 The Big picture…
