Ir. P.C. Roling ICRAT Conference 2004 Zilina, Republic of Slovakia Improvements to the Airport Business Suite A decision support system for airport development, planning and operations

Overview The airport business suite consists of three layers: Graphical User Interface (GUI) Computational models Common Data-layer Currently mostly used by students Course Strategic Airport Planning Fourth year exercises Ideal testing ground

Models in the original ABS Model 2 Model 1 Model 4/5

Models in the original ABS Model 1: Demand forecasting Passenger demand based on city pairs Model 2: Airport capacity and delay Airside capacity: FAA airfield capacity model Delay: Network of queuing models Landside: IATA terminal capacity model Model 4/5: Economics Turnover, operational costs and investments

Improvements Model 1 replaced by flight schedule generator Aircraft based instead of passenger based More versatile Easier to use More possible growth scenarios (de-peak / peak) Model 4/5 removed Results proved unreliable Replaced with some data output for manual calculations

Graphical User Interface (GUI) Model 3 is actually the GUI The GUI allows the users to interact with the models and the data. Running peak-day cases Running yearly cases (collection of peakday cases) Editing parameters Creating new flight schedules Creating input for INM

Amsterdam Airport Schiphol (AMS) Exists from 1916 In 2003: KLM Main hub 4 th largest airport in Europe (#pax) 9 th largest airport worldwide (#pax) aircraft movements 39.9 Million passengers 1.3 Million tons of freight

AMS: Runway Expansion

AMS: 2003, 5P Base case (actual flight schedule used)

AMS: 2010, 5P : 6.85% peak-wise yearly growth

AMS: 2020, 5P : 2.96% peak-wise yearly growth

AMS: 2020, 5P : 2.96% normal yearly growth

AMS: 2020, 6P : 2.96% normal yearly growth

AMS: 2020, 6PK : 2.96% normal yearly growth

AMS: 2020 Storm Arrival Capacity 6P 6PK

Conclusions and Recommendations AMS 6PK seems the preferred choice for 2020 ABS Able to compute airport performance indicators Lot of manual input A lot of work comparing output Improvements will be used mostly for HARMOS
