Illegal contraband trafficking is causing serious damage in many countries. We focus on a subset of illegal maritime activities, mainly on weapon and drug trafficking. Our aim is to help naval authorities evaluate their currently deployed countermeasures by modeling the behavior of traffickers as realistically as possible, and evaluating the impact of countermeasures in an agent-based simulation. We introduce BANDIT, a simulation platform designed for this purpose. We propose a novel model of traffickers based on a state-of-the-art game-theoretical model using the latest results in behavioral modeling. We apply this model to specific scenarios for drug smuggling in the Caribbean, and we demonstrate the capabilities of the platform.
