Advantages of Modelling & Simulation

• Easy to understand: Helps clarify how a system operates without interacting with the live system.
• Easy to test: Allows changes to be made and their effects observed without risk to the real system.
• Easy to upgrade: Helps determine system requirements by testing different configurations.
• Easy to identify constraints: Enables bottleneck analysis to find delays in work processes or information flow.
• Easy to diagnose problems: Allows for understanding complex interactions and exploring new policies or procedures without affecting the real system.

Disadvantages of Modelling & Simulation

• Requires Expertise: Designing a model is an art requiring domain knowledge, training, and experience.
• Difficult to Predict: Results can be hard to predict as operations may be based on random numbers.
• Time-Consuming: Simulation requires significant manpower and is a time-intensive process.
• Difficult to Translate: Simulation results require experts for proper interpretation.
• Expensive: The process can be costly to implement.
