Benders Decomposition for Profit Maximizing Hub Location Problems with Capacity Allocation

Taherkhani, Gita; Alumur, Sibel A.; Hosseini, Seyed Mojtaba (2019-06)

This paper models capacity allocation decisions within profit maximizing hub location problems to satisfy demand of commodities from different market segments. A strong deterministic formulation of the problem is presented ...

Collection Center Location with Equity Considerations in Reverse Logistics Networks

Alumur, Sibel A.; Tari, Isil (Taylor and Francis, 2014-11-01)

In this paper, we study a collection center location problem with equity considerations within reverse logistics network design. The aim of the problem is to determine the locations and the capacities of the collection ...

The design of capacitated intermodal hub networks with different vehicle types

Serper, Elif Zeynep; Alumur, Sibel A. (Elsevier, 2016-04-01)

In this study, we allow using alternative transportation modes and different types of vehicles in the hub networks to be designed. The aim of the problem is to determine the locations and capacities of hubs, which ...

Modeling congestion and service time in hub location problems

Alumur, Sibel A.; Nickel, Stefan; Rohrbeck, Brita; Saldanha-da-Gama, Francisco (Elsevier, 2018-03-01)

In this paper, we present a modeling framework for hub location problems with a service time limit considering congestion at hubs. Service time is modeled taking the traveling time on the hub network as well as the handling ...

Multi-period hub network design problems with modular capacities

Alumur, Sibel A.; Nickel, Stefan; Saldanha-da-Gama, Francisco; Secerdin, Yusuf (Springer, 2016-11-01)

In this paper, a modeling framework is proposed for multi-period hub location. The problems to be studied are extensions of classical hub location problems to the situation in which the hub network can be progressively ...

Profit Maximizing Hub Location Problems

Taherkhani, Gita; Alumur, Sibel A. (Elsevier, 2019-07-01)

In this paper, we study profit maximizing hub location problems. We formulate mathematical models determining the location of hubs, designing the hub networks, and routing the demand in order to maximize profit. The profit ...

Recent advances in location analysis

Alumur, Sibel A.; Kara, Bahar Y. (Elsevier, 2015-10-01)

Introduction to a special issue of Computers & Operations Research dedicated to recent advances in location analysis.

Spatial Analysis of Single Allocation Hub Location Problems

Peker, Meltem; Kara, Bahar Y.; Campbell, James F.; Alumur, Sibel A. (Springer, 2016-12-01)

Hubs are special facilities that serve as switching, transshipment and sorting nodes in many-to-many distribution systems. Flow is consolidated at hubs to exploit economies of scale and to reduce transportation costs between ...
