A simulation approach to modelling baggage handling systems at an international airport

The baggage handling system is a critical component of an airport’s operations, coordinating many different elements and agents in different areas of the facility. Due to the complexity of their interrelationships, an effective analysis of the impact of different operating strategies on the system must consider these elements and agents not in isolation from each other but rather as an integrated whole. This paper presents a microscopic simulation model for a baggage handling system that fully integrates all baggage-related subsystems. These include passenger arrival to check-in queues, baggage check-in, security screening, sorting, transport to the aircraft and loading. Under this approach, not only the individual subsystems but also their interactions can be simulated and studied. The proposed simulator is applied to the case of Santiago International Airport in Chile where passenger demand has grown beyond the existing baggage handling system’s operating capacity. The principal contributions of this study are the extension and adaptation of a vehicle traffic simulator software to the baggage handling problem and the development of a platform that models baggage handling as an integrated unit. The tool is applied to the analysis of the overall system and its components under a number of different real-world scenarios. In this application, the movement of bags and their interactions with the rest of the system are simulated in great detail for a given period. This level of granularity permits the simulator to analyse accurately the effects of different scenarios and how they are propagated through the system.     

Model-based design of supervisory controllers for baggage handling systems

The complexity of airport baggage handling systems in combination with the required high level of robustness makes designing supervisory controllers for these systems a challenging task.We show how a state of the art, formal, model-based design framework has been successfully used for model-based design of supervisory controllers for an actual industrial baggage handling system, and for a real-time emulation model of an actual international airport.The high level modeling elements of the applied CIF model-based design framework allow the modeler to concentrate on implementing the baggage handling system design requirements, instead of programming PLC code. It also allows a modular and hierarchical design of the supervisory controller, and provides flexibility in adapting and extending the model. Validation of the controller and the uncontrolled plant by means of simulation and visualization made it possible to catch all modeling errors, leading to very short modeling, testing and error correction iteration loops.To the best of our knowledge, this is the first successful employment of formal, model-based design in the context of supervisory control for actual, industrial size baggage handling systems, that covers the entire development process from requirements up to and including validation, real-time PLC code generation and implementation.We give an overview of the model-based design framework, discuss several modeling issues, and analyze the results of the industrial applications. We do not go into full technical detail, due to nondisclosure agreements, but tell the story, and give lessons learned that we consider useful for practitioners.

Effects of Baggage Volume and Alarm Rate on Airport Security Screening Checkpoint Efficiency using Queuing Networks and Discrete Event Simulation

This study used queuing networks and discrete event simulation (DES) to investigate the effects of baggage volume and alarm rate at the security screening checkpoint (SSCP) of a small origin and destination airport. A queuing network was applied for theoretical modeling of the SSCP performance, and a DES model using Arena Version 12 was used for an empirical approach. Data were collected from both literature and by manual collection during the peak operating time of the airport that was modeled. The simulation model was verified and validated qualitatively and quantitatively by statistical testing before experimentation. After validation, a sensitivity analysis was performed on baggage volume of passengers (PAX) and the alarm rate of baggage screening devices, where SSCP throughput and PAX cycle time, were the dependent measures. The theoretical queuing network proved an accurate method of predicting cycle time for the system while in steady state but was subject to various assumptions. The empirical model and sensitivity analysis showed that SSCP throughput and cycle time are both highly sensitive to alarm rate. Additionally, the sensitivity analysis showed that SSCP throughput was completely resilient to baggage volume, while cycle time was moderately sensitive to baggage volume. Practical implications and future research were also discussed.     

Simulation-based baggage handling system merge analysis

This paper details the investigation into the design and control of merging bottlenecks of conveyor-based baggage handling systems, encompassing the merging control algorithm and the impact of the merge’s physical layout. A methodology for the analysis of simulation model results is presented. Results show that the layout of the merge influences bag throughput and when the physical configuration is in a preferred position, input variance has no effect on bag throughput performance. These results have potential application to other material handling systems, such as those used in manufacturing and warehousing.
