Surveillance and interdiction models : a game-theoretic approach to defend against VBIEDS

Abstract

This thesis develops a model for surveillance and interdiction operations by combining a tactical Unmanned Aerial Vehicle (UAV) to detect a threat with a ground force to interdict that threat. The scenario models the defense of a fixed facility such as a Forward Operating Base against an enemy attack in the form of a Vehicle Borne Improvised Explosive Device (VBIED). UAVs are increasingly more important in the military, and significant improvements in quantity and capability allow even tactical units to employ this tool, yet little research has been done on effective employment techniques at this level. Additionally, VBIEDs are a significant threat, but the primary counter-VBIED technique is simply hardened perimeter defenses, and little work has been done to detect and interdict a VBIED before it reaches the target. This research project addresses both deficiencies. Through spreadsheet and decision theory analysis, the factors that impact UAV and ground force employment are examined and effective strategies to employ the two together are considered. Then through Game Theory, the strategic interactions between attack and defender are modeled to examine how changes in the conditions can impact the optimal strategy choices for each side.
