System Simulation and
INTRODUCTION TO SIMULATION
SIMULATION is the imitation of the operation of a real-world process or system over
Purpose : researchers, analyst, professors, so that they can infer something.
Can simulate globe, planetarium, bank or online sale transactions, study of
The behavior of a system as it evolves over time is studied by developing a SIMULATION
SIMULATION-GENERATED DATA is used to estimate the measures of performance of
WHEN SIMULATION IS THE APPROPRIATE TOOL
Simulation can be used for the following purposes:
1. Simulation enables the study of, and experimentation with, the internal interactions of
a complex system or of a subsystem within a complex system.
2. Informational, organizational, and environmental changes can be simulated, and the
effect of these alterations on the model's behavior can be observed.
3. The knowledge gained in designing a simulation model may be of great value toward
suggesting improvement in the system under investigation.
4. By changing simulation inputs and observing the resulting outputs, valuable insight
may be obtained into which variables are most important and how variables interact.
5. Simulation can be used as a pedagogical device to reinforce analytic solution
6. Simulation can be used to experiment with new designs or policies prior to
implementation, so as to prepare for what may happen.
7. Simulation can be used to verify analytic solutions.
8. By simulating different capabilities for a machine, requirements can be determined.
9. Simulation models designed for training allow learning without the cost and disruption
of on-the-job learning.
10. Animation shows a system in simulated operation so that the plan can be visualized.
11. The modern system (factory, wafer fabrication plant, service organization, etc.) is so
complex that the interactions can be treated only through simulation.
