Facility dispersion problems involve placing a number of facilities as far apart from each other as possible. Four different criteria of facility dispersal have been proposed in the literature (Erkut & Neuman, 1991). Despite their formal differences, these four classic dispersion objectives can...

Systematic approaches to security investment decisions are crucial for improved homeland security. We present an optimization modeling approach for allocating protection resources among a system of facilities so that the disruptive effects of possible intentional attacks to the system are...

In order to design a coverage-type service network that is robust to the worst instances of long-term facility loss, we develop a facility location-interdiction model that maximizes a combination of initial coverage by p facilities and the minimum coverage level following the loss of the most...
