Advantages and Disadvantages

Main advantages of simulation include:

• 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.

Main disadvantages of simulation include:

• Expensive to build a simulation model.
• Expensive to conduct simulation.
• Sometimes it is difficult to interpret the simulation results.
