    • Green hub location problem 

      Dükkancı, Okan; Peker, Meltem; Kara, Bahar Y. (Elsevier, 2019)
      This paper introduces the green hub location problem that finds the best locations for hubs, assignments of demand nodes to these hubs and speed of trucks/flights so as to route the demand between any origin-destination ...
    • Green location and routing problems with conventional vehicles and drones 

      Dükkancı, Okan (Bilkent University, 2019-05)
      Green Location and Routing Problems extend the network design problems that consider location and routing decisions by explicitly accounting environmental impacts such as CO2 emissions caused by fuel or energy consumption ...
    • The green location-routing problem 

      Dükkancı, Okan; Kara, Bahar Y.; Bektaş, Tolga (Elsevier, 2019)
      This paper introduces the Green Location-Routing Problem (GLRP), a combination of the classical Location-Routing Problem (LRP) and the Pollution-Routing Problem (PRP). The GLRP consists of (i) locating depots on a subset ...
    • The green network design problem 

      Dükkancı, Okan; Bektaş, T.; Kara, Bahar Y. (Elsevier, 2019)
      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 ...
    • Routing and scheduling decisions in the hierarchical hub location problem 

      Dükkancı, Okan; Kara, Bahar Y. (Elsevier, 2014)
      Hubs are facilities that consolidate and disseminate flow in many-to-many distribution systems. The hub location problem considers decisions that include the locations of hubs in a network and also the allocations of the ...
