5 important questions on Basic Simulation Modeling

Key element in the dynamics of simulation

the interaction between the simulation clock and the event

What's an event graph method

Events are represented by nodes and connected by directed arcs (arrows). Used to simplify a simulation's event structure by eliminating unnecessary events.

Simulation of an inventory system it is important to know that:

it will generally not be sufficient to make a single simulation run of each policy or system of interest

What are the steps in a simulation study?

• Formulate problem and goals
• Collect data, definemodel
• Validate conceptual model (improve if needed)
• Implement model (software)
• Verify program (correct if needed)
• Validate implemented model (improve if needed)
• Design experiments
• Execute experiments
• Analyze output data (sufficient?)
• Document and trepor

What are the pitfalls of simulation?

- Failure to identify objectives clearly upfront.
- Inappropriate level of detail.
- Inadequate design and analysis of simulation experiments.
- Failure to communicate with management sufficiently and regularly (credibility).
- Inadequate education, training.
- Misleading animation.
- Misleading results (single replication).
