Transportation Research Part C: Emerging Technologies0968-090Xhttp://hdl.handle.net/11441/43206The Single Allocation Ordered Median Hub Location problem is a recent hub model introduced in [36] J. Puerto, A.B. Ramos, and A.M. Rodríguez-Chía. Single-Allocation Ordered Median Hub Location Problems. Computers and Operations Research, 38:559-570, 2011.that provides a unifying analysis of a wide class of hub location models. In this paper, we deal with the capacitated version of this problem, presenting two formulations as well as some preprocessing phases for fixing variables. In addition, a strengthening of one of these formulations is also studied through the use of some families of valid inequalities. A battery of test problems with data taken from the AP library are solved where it is shown that the running times have been significantly reduced with the improvements presented in the paper.application/pdfengAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Hub locationDiscrete ordered median problemsCapacitiesinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccesshttps://doi.org/10.1016/j.trc.2015.05.012
