Reformulations and Computational Results for the Uncapacitated Single. Allocation Hub Covering Problem
Andreas T. Ernst; Jiang, Houyuan; Krishnamoorthy, Mohan; … - Judge Business School <Cambridge> - 2011
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 –...
