Allocation Strategies in Hub Networks
(Elsevier, 20110611)In this paper, we study allocation strategies and their effects on total routing costs in hub networks. Given a set of nodes with pairwise traffic demands, the phub median problem is the problem of choosing p nodes as hub ... 
A branch and cut algorithm for hub location problems with single assignment
(Springer, 2005)The hub location problem with single assignment is the problem of locating hubs and assigning the terminal nodes to hubs in order to minimize the cost of hub installation and the cost of routing the traffic in the network. ... 
A branchandcut algorithm for the hub location and routing problem
(Elsevier, 2014)We study the hub location and routing problem where we decide on the location of hubs, the allocation of nodes to hubs, and the routing among the nodes allocated to the same hubs, with the aim of minimizing the total ... 
A capacitated hub location problem under hose demand uncertainty
(Elsevier, 2017)In this study, we consider a capacitated multiple allocation hub location problem with hose demand uncertainty. Since the routing cost is a function of demand and capacity constraints are imposed on hubs, demand uncertainty ... 
The design of single allocation incomplete hub networks
(Elsevier, 2009)The hub location problem deals with finding the location of hub facilities and allocating the demand nodes to these hub facilities so as to effectively route the demand between any origindestination pair. In the extensive ... 
Efficient simulated annealing based solution approaches to the competitive single and multiple allocation hub location problems
(Elsevier, 2018)Hub location problems (HLPs) constitute an important class of problems in logistics with numerous applications in passenger/cargo transportation, postal services, telecommunications, etc. This paper addresses the competitive ... 
Endogenous effects of hubbing on flow intensities
(Springer, 2016)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 ... 
The hierarchical hub median problem with single assignment
(Elsevier, 2009)We study the problem of designing a three level hub network where the top level consists of a complete network connecting the socalled central hubs and the second and third levels are unions of star networks connecting ... 
Hierarchical multimodal hub location problem with timedefinite deliveries
(Elsevier, 2012)Hierarchical multimodal hub location problem is a costminimizing hub covering problem where two types of hubs and hub links, accounting for ground and air transportation, are to be established, while ensuring timedefinite ... 
A hub covering network design problem for cargo applications in Turkey
(Palgrave Macmillan, 2009)Hub location problems involve locating hub facilities and allocating demand nodes to hubs in order to provide service between origindestination pairs. In this study, we focus on cargo applications of the hub location ... 
Hub location and Hub network design
(Bilkent University, 2009)he hub location problem deals with finding the location of hub facilities and allocating the demand nodes to these hub facilities so as to effectively route the demand between origin–destination pairs. Hub location ... 
Hub location and routing problem
(Bilkent University, 201601)Hubs are special facilities that consolidate and disseminate ows in manytomany distribution systems. The hub location problem aims to nd locations of hubs and allocate nonhub nodes directly to the hubs. However, ... 
Hub location proplems under polyhedral demand uncertainty
(Bilkent University, 201507)Hubs are points of consolidation and transshipment in manytomany distribution systems that bene t from economies of scale. In hub location problems, the aim is to locate hub facilities such that each pairwise demand ... 
Hub location under competition
(Bilkent University, 2013)Hubs are consolidation and dissemination points in manytomany flow networks. The hub location problem is to locate hubs among available nodes and allocate nonhub nodes to these hubs. The mainstream hub location studies ... 
Hub location under competition
(Elsevier, 2016)Hubs are consolidation and dissemination points in manytomany flow networks. Hub location problem is to locate hubs among available nodes and allocate nonhub nodes to these hubs. The mainstream hub location studies ... 
The latest arrival hub location problem for cargo delivery systems with stopovers
(Elsevier, 2007)In this paper, we concentrate on the service structure of groundtransportation based cargo delivery companies. The transient times that arise from nonsimultaneous arrivals at hubs (typically spent for unloading, loading, ... 
Multimodal hub location and hub network design
(2012)Through observations from real life hub networks, we introduce the multimodal hub location and hub network design problem. We approach the hub location problem from a network design perspective. In addition to the location ... 
Network hub location problems: The state of the art
(Elsevier, 2008)Hubs are special facilities that serve as switching, transshipment and sorting points in manytomany distribution systems. The hub location problem is concerned with locating hub facilities and allocating demand nodes to ... 
On the singleassignment phub center problem
(Elsevier, 2000)We study the computational aspects of the singleassignment phub center problem on the basis of a basic model and a new model. The new model's performance is substantially better in CPU time than different linearizations ... 
phub median problem for noncomplete networks
(Elsevier, 2018)Most hub location studies in the literature use a completenetwork structure as an input in developing optimization models. This starting point is not necessarily from assuming that the underlying realworld network (e.g., ...
