A game theoretic model for resource allocation among countermeasures with multiple attributes

We study a strategic, two-player, sequential game between an attacker and defender. The defender must allocate resources amongst possible countermeasures and across possible targets. The attacker then chooses a type of threat and a target to attack. This paper proposes a model for determining optimal resource allocation by combining game theory with a simple multi-attribute utility model. Given a set of possible attributes representing goals or preferences, we allow each player to choose a weight for each attribute, where the subset of attributes with nonzero weights represents that player’s preferences. Every countermeasure is given a score for its effectiveness at both mitigating the effects of an attack in terms of each attribute and reducing the probability of the success of an attack. Furthermore, the consequences of each possible attack are scored in terms of each attribute. The multi-attribute utility aspect of this model uses these scores, along with the players’ weights, to form the basis of the utility (or disutility) for each player. We find that (i) the zero-sum game where the attacker’s and defender’s weights are identical results in the worst losses for the defender, (ii) in general cases the defender’s equilibrium strategy has the result of making the attacker indifferent between multiple attacks and (iii) the use of target-independent countermeasures (i.e. countermeasures which operate at national levels as opposed to operating at differing levels for each target) can increase the cost-effectiveness of countermeasures

Prevention of terrorism : an assessment of prior POM work and future potentials

© 2020 Production and Operations Management Society In this study, we review POM-based research related to prevention of terrorism. According to the Federal Emergency Management Agency (FEMA) terrorist attacks have the potential to be prevented. Consequently, the focus of this study is on security enhancement and improving the resiliency of a nation to prevent terrorist attacks. Accordingly, we review articles from the 25 top journals, [following procedures developed by Gupta et al. (2016)], in the fields of Production and Operations Management, Operations Research, Management Science, and Supply Chain Management. In addition, we searched some selected journals in the fields of Information Sciences, Political Science, and Economics. This literature is organized and reviewed under the following seven core capabilities defined by the Department of Homeland Security (DHS): (1) Intelligence and Information Sharing, (2) Planning, (3) Interdiction and Disruption, (4) Screening, Search, and Detection, (5) Forensics and Attribution, (6) Public Information and Warning, and (7) Operational Coordination. We found that POM research on terrorism is primarily driven by the type of information that a defending country and a terrorist have about each other. Game theory is the main technique that is used in most research papers. Possible directions for future research are discussed
