19.6 Exercises

The Borealian Aeronautic Security Agency (BASA) runs pre-board screening of passengers and crew for all flights departing the nation’s airfields.

There are 4 Major Airfields:

• Auckland

• Chebucto

• Saint-François

• Queenston

The screening process (PBS) is structurally similar at each airfield:

1. Passengers arrive at the beginning of the main queue

2. Boarding passes may or may not be scanned at S_1

3. Passengers enter the main queue

4. Boarding passes are scanned at S_2

5. Passengers are directed to a server entry position

6. Passengers and carry-on luggage are screened by a server

Some factors influence the PBS wait time, including:

• schedule intensity of departing flights

• passenger volume on these flights

• number of servers and processing rates at a given airfield, etc.

There might also be:

• yearly, seasonal, time-of-day, day-of-week interaction effects (among others) depending on the airfield, the flight destination, etc.

• trend level shifts in the number of passengers, flights, destinations, etc.

Four datasets are available: 20262030.csv, BASA_AUC_2028_912.csv, dat_F_sub.csv, dat_P_sub_c.csv.

1. Build a data dictionary for the datasets

2. Explore and visualize the datasets

3. Perform a queueing model analysis to predict the wait times at each airfield for which you have data.

Use Case Study ?? to inform your analysis.
