Therefore, an existing CAST Aircraft model was updated for the stand occupancy analysis considering the future airport layout and a CAST Express model was built for detailed allocation rules and Level of Service analysis of terminal facilities.
The analysis results from different scenarios were used to provide recommendations on which allocation scenario is most promising and when certain actions for optimizations should start. Next to presenting the results by graphs and figures, ARC delivered the simulation models to support the further analysis by the in-house planning team of Singapore Changi Airport.
At the time of the study Singapore Changi Airport (CAG) was in the planning stage of the new Terminal 5 in the distant future and therefore needed to set a plan for operating the existing terminals before opening of the new terminal. The study was based on a set of different scenarios on terminal usage by major airlines and various flight schedules developed by CAG. ARC was asked to evaluate the level of service of terminal facilities considering the increasing number of flights and passengers, as well as stand and counter occupancy and availabilities in the future.
