Hub Covering Location Problem Considering Queuing and Capacity Constraints [PDF]

open access: yesJournal of Optimization in Industrial Engineering, 2018
In this paper, a hub covering location problem is considered. Hubs, which are the most congested part of a network, are modeled as M/M/C queuing system and located in placeswhere the entrance flows are more than a predetermined value.A fuzzy constraint ...

Dynamic Hub Covering Problem with Flexible Covering Radius

open access: yesInternational Journal of Industrial Engineering and Production Research, 2015
One of the basic assumptions in hub covering problems is considering the covering radius as an exogenous parameter which cannot be controlled by the decision maker. Practically and in many real world cases with a negligible increase in costs, to increase
