A branch and price approach for routing and refueling station location model
The deviation flow refueling location problem is to locate p refueling stations in order to maximize the flow volume that can be refueled respecting the range limitations of the alternative fuel vehicles and the shortest ...
The splittable flow arc set with capacity and minimum load constraints
We study the convex hull of the splittable flow arc set with capacity and minimum load constraints. This set arises as a relaxation of problems where clients have demand for a resource that can be installed in integer ...
A polyhedral study of multiechelon lot sizing with intermediate demands
(Institute for Operations Research and the Management Sciences (I N F O R M S), 2012)
In this paper, we study a multiechelon uncapacitated lot-sizing problem in series (m-ULS), where the output of the intermediate echelons has its own external demand and is also an input to the next echelon. We propose a ...
The green network design problem
Logistics activities are at the heart of world trade, but they also have unintended consequences on the environment due to the use of land, energy, and other types of natural resources. The significant energy usage by the ...
Endogenous effects of hubbing on flow intensities
Location of hub facilities and the allocation decisions in transport networks endogenously affect both the flow intensities and the transportation costs. Since the introduction of the hub location problem to the operations ...
