Happy Airways, a small-scale budget airline, currently provides jet services between Sydney and Melbourne. They wish to expand their business to serve the surge in demand for jet passengers from/to Canberra. Their promise is to fly all the passengers presented at the airport service counters, i.e., if a scheduled flight is full then alternative flight will be organised. The airline evaluates its ground operations performance based on three key metrics (KPIs):

• average time taken by a passenger to move from check-in to boarding; • average time taken for a piece of luggage to move from check-in to the aircraft loading area; • average wait time for a passenger in each category at check-in and boarding counters; and • average utilisation of staff at check-in, security and boarding counters. The ground operations of the airline are organised so that they can perform check-in, security check, and boarding counter services to cater for three types (categories) of passengers: passengers with e-tickets, passengers with paper-based tickets and passengers purchasing a ticket at the airport counter. Based on historical records, it has been estimated that the time between passenger arrivals in each category (e-ticket, paper-based and purchased at the counter) are five, ten and thirty minutes, respectively. The service terms of Happy Airways are such that each passenger has 1 checked-in luggage and 1 cabin luggage. All passengers must go through check-in, security check and boarding counters. Further details of the ground operations of their proposed Canberra terminal are given below. Check-in: All check-ins are handled by the airline ground staff. Passengers usually arrive at the check-in counters at the designated airport terminal and hand over any luggage that is not allowed to carry on to the airplane’s cabin. Passengers receive a boarding pass after luggage handover which they use for boarding the airplane. The service times for the three passenger types at the check-in counters are as follows; passengers with e-ticket requires, on average three minutes, for passengers with paper tickets it takes eight minutes on average, and for the passengers who purchase their tickets at the airport counter spends twelve minutes on average at check-in. Additionally, it takes two, four and six minutes, respectively, for the staff to properly register and label luggage of passengers with an e-ticket, paper-based tickets and the tickets issued at the counter. Each staff at the check-in counter is designated to service only one particular type of passenger. Security check: A security check is conducted for each passenger and accompanying cabin bag after checking in and before boarding. This is done to mitigate the risks of any potential threats or other criminal activities. As passengers approach the security check point, there are designated bins to surrender any prohibited items or liquids. Then passengers are asked to walk through a body scanner where one of the security staff supervises body scans. It generally requires ten seconds for them to do such screening. In nearly 10% of the cases, if the body scanner alarm sets off, passengers are asked by the screening officer to remove any further objects held on to their clothes or body and passengers are then asked to walk again through the device. Simultaneously, cabin bags are screened with the help of x-ray machines. The cabin bags are placed on small trays provided at the screening point. One of the security officers examines the images of the bags as they pass through the x-ray machine and it takes ten seconds per bag to move through it. Boarding operation: The passengers then proceed to the designated boarding gate and board the aircraft. The airline staff checks boarding passes issued at the check-in counters. A boarding pass is a document issued by the airline that permits a passenger to board the airplane. It normally includes details about the passenger, the flight number and the date and scheduled time for departure. It takes normally thirty seconds for a staff
