What is it about?
A defender defends and an attacker attacks each of n interdependent targets which can operate or fail and be in 2^n possible states. Interdependence is modeled from each target to each other target. Despite such systems usually being analyzed numerically, this paper succeeds in determining analytical solutions, accounting for unit effort costs, target values, and contest intensities.

Why is it important?
Increasing interdependence from some targets to some other targets induce both players to exert higher efforts into the former targets. For 100% interdependent targets the attacker encounters a substitution effect. In contrast, for independent targets the defender encounters a substitution effect, defending the essential targets. For similarly advantaged players increased target contest intensities cause higher efforts and lower expected utilities. Both players may withdraw in both 100% interdependent and independent systems.
