-hub center problem is an extension of the deterministicversion which aims to minimize the longest origin-destination path in a hub and spokenetwork. Considering the stochastic nature of travel times on links is important when designing anetwork to guarantee the quality of service measured by a...

We study the single allocation hub covering problem, which is a special case of the general hub locationproblem. The hub covering problem is also an important extension to traditional network coveringproblems. Hubs are located at some nodes in the network and are used to facilitate –...
