      Bilkent Üniversitesi, personeline kampus ve şehrin çeşitli noktaları arasında taşıma hizmeti vermektedir. Bu amaçla kurulmuş olan ulaşım sisteminin ölçeği ve maliyeti oldukça büyüktür. Bu çalışmanın amacı bu hizmeti, ...
    • A branch-and-cut algorithm for the alternative fuel refueling station location problem with routing 

      Arslan, O.; Karaşan, Oya Ekin; Mahjoub, A. R.; Yaman, Hande (INFORMS, 2019)
      Because of the limited range of alternative fuel vehicles (AFVs) and the sparsity of the available alternative refueling stations (AFSs), AFV drivers cooperatively deviate from their paths to refuel. This deviation is ...
    • Branch-and-price approaches for the network design problem with relays 

      Yıldız, B.; Karaşan, Oya Ekin; Yaman, Hande (Elsevier, 2018)
      With different names and characteristics, relays play a crucial role in the design of transportation and telecommunication networks. In transportation networks, relays are strategic locations where exchange of drivers, ...
    • Convex hull results for the warehouse problem 

      Wolsey, L. A.; Yaman, Hande (Elsevier B.V., 2018)
      Given an initial stock and a capacitated warehouse, the warehouse problem aims to decide when to sell and purchase to maximize profit. This problem is common in revenue management and energy storage. We extend this problem ...
    • Damacana su pazar analizi ve dağıtım ağı tasarımı 

      Ayabakan, Sezgin; Çelik, Ayşe; Erdoğan, Ezgi; Karakan, Ceylan; Koçak, Serkan; Konur, Dinçer; Yaman, Hande (TMMOB Makina Mühendisleri Odası, 2007)
      Damacana su pazarı Türkiye’de hızlı bir büyüme potansiyeline sahiptir. Coca Cola İçecek A.Ş. Mahmudiye su tesislerini satın alarak doğal kaynak suyu üretimine başlamıştır. Şirket Ankara’da Damla markası adı altında damacana ...
    • Essays on some combinatorial optimization problems with interval data 

      Yaman, Hande (Bilkent University, 1999)
      In this study, we investigate three well-known problems, the longest path problem on directed acyclic graphs, the minimum spanning tree problem and the single machine scheduling problem with total flow time criterion, ...
    • A hybrid polyhedral uncertainty model for the robust network loading problem 

      Altın, A.; Yaman, Hande; Pınar, Mustafa Ç. (Springer, New York, 2011)
    • k-node-disjoint hop-constrained survivable networks: polyhedral analysis and branch and cut 

      Diarrassouba, I.; Mahjoub, M.; Mahjoub, A. R.; Yaman, Hande (Springer-Verlag France, 2018)
      Given a graph with weights on the edges, a set of origin and destination pairs of nodes, and two integers L ≥ 2 and k ≥ 2, the k-node-disjoint hop-constrained network design problem is to find a minimum weight subgraph of ...
    • Multi-stage stochastic programming for demand response optimization 

      Şahin, Munise Kübra; Çavuş, Özlem; Yaman, Hande (Elsevier, 2020-02-19)
      The increase in the energy consumption puts pressure on natural resources and environment and results in a rise in the price of energy. This motivates residents to schedule their energy consumption through demand response ...
    • New exact solution approaches for the split delivery vehicle routing problem 

      Özbaygın, Gizem; Karasan, Oya Ekin; Yaman, Hande (Springer Verlag, 2018)
      In this study, we propose exact solution methods for the split delivery vehicle routing problem (SDVRP). We first give a new vehicle-indexed flow formulation for the problem and then a relaxation obtained by aggregating ...
    • p-center problems 

      Çalık, Hatice; Labbé, M.; Yaman, Hande (Springer, 2015)
      A p-center is a minimax solution that consists in a set of p points that minimizes the maximum distance between a demand point and a closest point belonging to that set. We present different variants of that problem. We ...
    • The periodic vehicle routing problem with driver consistency 

      Rodríguez-Martín, I.; Salazar-González, J. -J.; Yaman, Hande (Elsevier, 2019)
      The Periodic Vehicle Routing Problem is a generalization of the classical capacitated vehicle routing problem in which routes are determined for a planning horizon of several days. Each customer has an associated set of ...
    • Shelter location and evacuation route assignment under uncertainty: a benders decomposition approach 

      Bayram, V.; Yaman, Hande (INFORMS Inst.for Operations Res.and the Management Sciences, 2018)
      Shelters are safe facilities that protect a population from possible damaging effects of a disaster. For that reason, shelter location and traffic assignment decisions should be considered simultaneously for an efficient ...
    • Stochastic lot sizing problem with nervousness considerations 

      Koca, E.; Yaman, Hande; Aktürk, M. Selim (Elsevier, 2018)
      In this paper, we consider the multistage stochastic lot sizing problem with controllable processing times under nervousness considerations. We assume that the processing times can be reduced in return for extra cost ...
