Application virtualization is likely to play a crucial role in consolidating electronic military health records to help improve the care provided to current and former military members. However, due to bandwidth and other resource constraints, virtualization resources can only be located at a limited number of military treatment facilities within the Military Health System (MHS). This article provides an optimization model to help guide the location of virtualization hubs among a subset of facilities within the MHS, as well as the allocation of demand to those hubs. The objective is to maximize the minimum probability that the response time is no more than a user specified threshold. Computational results show that networks with well over 200 facilities can be solved.
