Insurgency conflicts pose significant challenges to societies globally. The increase of insurgency conflicts creates a need to understand how insurgencies arise, and to identify societal drivers of insurgencies or effective strategies to counter them. In this paper, we analyze the contributions of computational modeling methods for the analysis...

Technological innovations such as digitalisation have an increasingly important role in our society. This development is also reflected in police work. In particular, the access to information on a global scale has increased the international character, adaptivity, and fluidity of criminal organisations. As such, there is a pressing need to...

Homicide investigators in the digital era have access to an increasing amount of data and the processing of all persons of interest and pieces of evidence has become nearly impossible. This paper describes the development and evaluation of a case-specific element library (C-SEL) that can be used to incorporate and prioritize persons of interest...

In this paper, we introduce partially observable agent-intruder games (POAIGs). These games model dynamic search games on graphs between security forces (an agent) and an intruder given possible (border) entry points and high value assets that require protection. The agent faces situations with dynamically changing, partially observable...

In this paper, we consider the optimal deployment of multiple assets in anti-submarine warfare (ASW) operations with time-dependent strategies. We model this as a zero-sum game that takes place over a finite time horizon. An agent, representing multiple assets, in an ASW operation, decides on the allocation of these assets (e.g., one or more...

Organized crime, insurgency and terrorist organizations have a large and undermining impact on societies. This highlights the urgency to better understand the complex dynamics of these individuals and organizations in order to timely detect critical social phase transitions that form a risk for society. In this paper we introduce a new multi...

Este trabalho trata do planejamento para aquisição e download de dados, dada uma constelação de satélites e de estações de solo, visando o monitoramento de áreas de interesse (alvos) com diferentes prioridades para um dado horizonte de planejamento. Um modelo matemático foi proposto anteriormente para tratar o problema, onde a capacidade do...

In this paper two Bayesian approaches and a frequency approach are compared on predicting offender output variables based on the input of crime scene and victim variables. The K2 algorithm, Naïve Bayes and frequency approach were trained to make the correct prediction using a database of 233 solved Dutch single offender/single victim homicide...

This paper provides a comparison between four methodologies that assist criminal investigators in homicide investigations. The Person of Interest Priority Assessment Tool, Trace Investigate and Evaluate, Rasterfahndung, and Analysis of Competing Hypotheses are compared on their performance in the collection, prioritization, and elimination phase...

The operational use of satellite systems has been increasing due to technological advances and the reduced costs of satellites and their launching. As such it has become more relevant to determine how to better use these new capabilities which is reflected in an increase in application studies in this area. This work focuses on the problem of...

In this chapter we consider a security game between an agent and an intruder to find optimal strategies for patrolling against illegal fishery. When patrolling large areas that consist of multiple cells, several aspects have to be taken into account. First, the current risk of the cells has to be considered such that cells with high risk are...

This paper considers a special case of security games dealing with the protection of a large area divided in multiple cells for a given planning period. An intruder decides on which cell to attack and an agent selects a patrol route visiting multiple cells from a finite set of patrol routes such that some given operational conditions on the...

The hyper connectivity of global, regional and local societies has increased the dynamics and volatility of conflicts. Conflicts are no longer contained by borders and ideologies and call for an integrated approach that takes into consideration the involved opponent organisations. However, limited modelling tools are available to provide insight...

Unmanned Aerial Vehicles (UAVs) are important assets for information gathering in Intelligence Surveillance and Reconnaissance (ISR) missions. Depending on the uncertainty in the planning parameters, the complexity of the mission and its constraints and requirements, different planning methods might be preferred. The first two planning...

Het aantal vermissingen is de laatste jaren steeds toegenomen, volgens Landelijk Bureau Vermiste Personen (De Telegraaf 2014), en het hoge aantal vereist een grote politie-inspanning. Het efficiënt en effectief aanpakken van een vermissing wordt dus alleen maar belangrijker. Dit artikel gaat in op de huidige werkwijze en problematiek bij...
