a$)$ You are the owner$/$manager of a fast food restaurant. Give an example of a business

decision that simulation modeling could help you make.

b$)$ When is it inappropriate to use simulation modeling?

$4)$ A self$-$serve car wash has three bays. Customers arrive, on average, every $10$ minutes

$($exponentially distributed$)$ and wait in the single file line for the next available wash bay.

When a wash bay is available, the next customer enters and washes their car, which takes an

average of $6$ minutes $($exponentially distributed$).$

To build a simulation model of this system we need to define the basic pieces of the model

$($see chapter $2\mathrm{.}3$ of our textbook$).$

a$)$ What are the entities? Please explain how you made your decision.

b$)$ What are the resources? Please explain how you made your decision.
