Passenger Security Process Demand & Capacity Prediction

Project Overview

In order to optimize the security checkpoint waiting times, Düsseldorf Airport was looking for a system that allows to predict the number and show-up times of incoming passengers at the security checkpoints. This allows a predictive and efficient planning of required security checkpoint resources.


The requirement for the optimized calculation approach was:

  • accurately forecast the number of expected passengers and their show-up time at the security checkpoints
  • calculate the staff requirements per time interval on an annual/monthly/weekly/daily base
  • optimize the staffing schedules to continuously fulfil the desired service levels and avoid idle times

Services provided

On-site measurements were used to gain knowledge about the passenger behavior (e.g. show-up time at the security checkpoint) or operational conditions (e.g. throughput per lane). With SECURITY MANAGEMENT SOLUTION powered by CAST, ARC applied a simulation model to cluster all information and to calculate the annual working hours to the best possible extent.

Real-Life tests have finally proven that ARC’s calculation method is valid and leads to accurate results, which more than fulfil the client’s expectations. Conducting workshops and interviews with all stakeholders to support the change management process which arose by the optimized allocation of labor-hours.

Results and Benefit

In the course of this project, a comprehensive calculation algorithm to predict the required security checkpoint resources was elaborated. The optimized staffing does not only improve the level of service for passengers (e.g. waiting times) but also reduces the annual working hours and thus costs at the airport. To achieve these aims, a close collaboration between the airport, Federal Police, ministry and airlines was required. ARC coordinated the collaboration between these stakeholders and – as a side effect of this study – improved their cooperation.

“The security checkpoint situation at Dusseldorf Airport has significantly improved compared to last year. We as an airline, as well as our customers, have benefited enormously from this improvement, which has led to less flights being delayed due to late passengers at the gate. We are very pleased that ARC made the customer journey at Dusseldorf Airport easier and faster.”
