Abstract: This paper proposes a model and solution techniques for integrated staffing and shift scheduling decisions in a 24/7 cybersecurity operations center. We model this problem as a two-stage stochastic shift scheduling problem over a 14-day pay period with three possible shifts per day, several staffing and scheduling constraints, uncertain demand and on call staffing options. To solve this problem, we discretize this problem into a single integer program and solve it using a column generation based heuristic. Computational results are included. This work is joint work with Dr. Doug Altner (MITRE).
