Simulation Analysis

**System Description:** The Barbaker Supermarket, operating in an area of Bleaksburg, attracts both *express* (quick, few items) and *regular* shoppers. A recent study has produced a set of data on the time between arrivals (inter-arrival times) of all shoppers and determined that 70% of all shoppers are *regular* shoppers. The remaining are *express* shoppers. All times are given in seconds.

On arrival, all regular shoppers observe if a shopping cart is available. If a cart is not available, the regular shopper angrily leaves before entering the store. If a cart is available, the regular shopper joins the queue for carts. Selection of a cart and extricating it from the others takes between five and fifteen seconds, distributed uniformly. Express shoppers hand carry the few items they need or use a small hand-carried basket, and plenty of them are available. The shopping times of both regular and express shoppers have been sampled, and the sampled values have resulted in the data models described below. At the conclusion of shopping, express customers join the single queue for the express cashier. Regular customers join the shortest queue for one of three cashiers, and if the length is the same, customer preferences are in the order Q1, Q3, Q2. Checkout time data for both regular and express customers have been sampled, and the data files are available. Since cashiers are not assigned to a specific register, no effort has been made to distinguish among the three serving regular shoppers (the data are descriptive of all three checkouts).

On completing checkout, express shoppers leave the store immediately. Regular shoppers use the cart to transport their purchases to their car in 60 percent of the cases. Sample data for the time for transport, unloading and return of the cart is provided in a file described below.
