1. Pick a local fast-food restaurant that has a drive through service, and think how to build a DES simulation model.

a) Develop a structural model for simulating the drive through process. What are the entities and what are the resources? Show the flowchart using SIMIO modules.

b) Identify the set of input parameters that you need to collect data for input modeling, specify whether they are deterministic or random variables. List a few output variables that you may want to collect data for later validation purpose.
