1:

Pg. 131, chapter 5: Properties are input values that can be specified when you place (or instantiate) an object into your model while States are dynamic values that change as the model executes.

2:

The parent object is the server itself - an instance of the object in which the “serving process” is defined. The assoicated object is the object that gets the server to start working in the first place.

For this model, I first tried JaamSim and while I was successful I was having some issues with figuring out how the ExpressionEntity could make some calculations so I ended up creating the model in Simio.

Model 5-1 in JaamSim

As shown above, the JaamSim example requires many components while the Simio version is rather streamlined, below:

Model 5-1 in Simio

I have a number of thoughts about relative strengths and weaknesses of each that I will save for now.

Here are the results of the Simio model that show the output matches table 5.2:

Model 5-1 Simio Results

4, 5:

Please find the model, created in Simio, below:

Model 5-7 Simio Model

Below, please find the results from 300 replications of 8hrs each. I have included the average and maximum of the runs. It appears that on average, a DMV customer will spend at least 30 minutes and up to 45 minutes to complete the process.

Model 5-7 Simio Results

The ease of use of Simio is quite remarkable.
