It is concerned that current designs in airport terminals need to be adaptable in terms of time and cost increasing their capacity to be able to meet demand. The terminal functionality is limited for some issues in the system’s performance as queues or delays, affecting the quality perceived by the passengers about the provided service. According to current research, the check-in area is considered the bottleneck in the facilities of the terminal. Consequently, the system needs to be reconfigured to improve its operation. Passengers can chose the traditional manual check-in at the counter or self-service automatic kiosk and bag drop. In this project, real-time information system will be provided using passenger throughput information to create flow path simulation for the domestic terminal in the Brisbane Airport. By building the simulation model, the system’s structure will be explored and the behaviour tested under a variety of conditions to play and compare scenarios to optimize the procedure. Ultimately, renovations will be made to the facility with the aim to minimize average dwell time and improve overall customer satisfaction. The ability to react quickly to the increasing passenger fluctuations with rapid and inexpensive changes in the check-in configuration would be the major contribution of the thesis. The strategy presented as a solution for a real world problem supports the adaptation of check-in facilities to the different dynamic environments in other airports.
