- 요약In an increasingly complex and interconnected world, ensuring security and resiliencerequires effective allocation of inspection resources to detect illegal activities. The evolving nature of threats, coupled with resourceful adversaries and limited inspection resources,makes it imperative to develop strategic inspection operations. Challenges include coordinating multiple resources, accounting for imperfect detection capabilities and asymmetricvaluations of targets. New opportunities, such as advances in sensing technologies and dataanalytics, offer potential solutions to enhance the effectiveness of inspection operations.This thesis leverages game theory for the strategic coordination of inspection resources,focusing on Nash Equilibria (NE) as the main solution concept. It aims to provide valuableinsights and efficient algorithms for inspection operations across various security domains.Chapter 2 examines a variant of the hide-and-seek game, motivated by the challengeof detecting smuggled commodities hidden by criminal organizations. In this game, aseeker inspects multiple hiding locations to find multiple items hidden by a hider. Eachhiding location has a maximum hiding capacity and a probability of detecting its hiddenitems upon inspection. The seeker (resp. hider) aims to minimize (resp. maximize) theexpected number of undetected items. We develop a two-step solution approach to compute NE for this zero-sum game. First, we solve a lower-dimensional continuous gameto derive closed-form expressions for the equilibrium marginal distributions. Second, wedesign a combinatorial algorithm to compute mixed strategies that satisfy these marginaldistributions. Our approach reveals novel equilibrium behaviors influenced by the complexinterplay of game parameters and computes NE in quadratic time with linear support.Chapter 3 explores a nonzero-sum variant of the hide-and-seek game, driven by theasymmetric valuations that security agencies and criminal organizations place on the outcomes of their interactions. Here, a seeker inspects multiple locations with unit hidingcapacities to find items hidden by a hider. Each location is associated with different utility values for the seeker and hider. The seeker (resp. hider) aims to maximize the utility frominspected (resp. uninspected) locations containing hidden items. We extend the previoustwo-step approach to obtain NE by deriving closed-form expressions for the equilibriummarginal distributions and computing compatible mixed strategies, resulting in a quadratictime algorithm for solving this nonzero-sum game. Our analysis not only reveals complexequilibrium behaviors influenced by the players' asymmetric and heterogeneous valuations,but also addresses strategic interactions in various contexts beyond security domains, suchas animal behavior and political campaigns. By offering both an intuitive analysis and anefficient solution method, this work bridges a gap in the study of equilibrium behavior innonzero-sum games of strategic mismatch.Chapter 4 addresses strategic inspection problems in critical infrastructure resiliencethrough a network inspection game, where a defender positions detectors on a network todetect multiple attacks on its components caused by an attacker. Each detector location hasa probability of detecting attacks within its monitored components. The defender (resp.attacker) aims to minimize (resp. maximize) the expected number of undetected attacks.This model extends the hide-and-seek game of Chapter 2 by allowing for detection frommultiple locations. To compute NE for this large-scale zero-sum game, we formulate alinear program with a small number of constraints and solve it using Column Generation.We provide an exact mixed-integer program for the pricing problem, which entails computing a defender's pure best response, and leverage its supermodular structure to derivetwo efficient approaches for obtaining approximate NE with theoretical guarantees: a Column Generation and a Multiplicative Weights Update (MWU) algorithm with approximatebest responses. Each iteration of our MWU algorithm requires computing a projection under the unnormalized relative entropy, for which we provide a closed-form solution and alinear-time algorithm. Our computational results in real-world gas distribution networksdemonstrate the performance and scalability of our solution approaches.
