Using Causal Discovery to Design Agent-based Models

Designing agent-based models is a difficult task. Some guidelines exist to aid modelers in designing their models, but they generally do not include specific details on how the behavior of agents can be defined. This paper therefore proposes the AbCDe methodology, which uses causal discovery algorithms to specify agent behavior. The methodology...

An empirical game-theoretic approach to airport security using agent-based modelling and simulation

Airports are attractive targets for terrorism, as they are designed to accommodate and process large amounts of people, resulting in high concentration of potential victims. A popular method to mitigate the risk of these attacks is through security patrols, but resources are often limited. Game-theory is often used as a methodology to find...

Quantifying Vulnerabilities in an Airport Checkpoint: A study on the role of employee behavior in the emergence of vulnerabilities

Ever since the attacks on the World Trade Center, airport security has been a topic of interest. The United States was caught by surprise and the attacks triggered a renewed interest in aviation security. It was well recognized that airport security was one step behind on intelligent attackers and this created the need to developed better risk...

Modelling and analysis of dynamic relations and trade-offs between security and efficiency in airport security operations

The two performance areas “security” and “efficiency” in airport security operations cannot be analyzed apart from each other, since influencing one has a large impact on the other. In this research agent-based modelling is used to analyze dynamic relations and trade-offs between security and efficiency within airport security operations....

Trade-off Analysis between Security and Efficiency of Airport Operations: A methodological underpinned modelling approach to identify, analyse and evaluate trade-offs based on empirical choice observations

This Master Thesis document presents a research on trade-off analysis between security and efficiency factors during airport operations. Over the past few decades there has been an increase in security in the air transportation industry, with even more measures taken since 9/11. Besides affecting the operational costs of airports, the stricter...
