Dinçerler, V. Alptekin; Güven, N. Engin; Tanrıkulu, M. Mustafa; Temel, Melih; Yitmen, Mehmet; Yaman, Hande (TMMOB Makina Mühendisleri Odası, 2004)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 branchandbound algorithm for team formation on social networks
Berktaş, Nihal; Yaman, Hande (Institute for Operations Research and the Management Sciences (INFORMS), 2021)The team formation problem (TFP) aims to construct a capable team that can communicate and collaborate effectively. The cost of communication is quantified using the proximity of the potential members in a social network. ... 
A branchandcut 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 ... 
Branchandprice 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 wellknown 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, ... 
Hub location, routing, and route dimensioning: strategic and tactical intermodal transportation hub network design
Yıldız, Barış; Yaman, Hande; Karaşan, Oya Ekin (Institute for Operations Research and the Management Sciences (INFORMS), 202110)We propose a novel hub location model that jointly eliminates some of the traditional assumptions on the structure of the network and on the discount as a result of economies of scale in an effort to better reflect realworld ... 
A hybrid polyhedral uncertainty model for the robust network loading problem
Altın, A.; Yaman, Hande; Pınar, Mustafa Ç. (Springer, New York, 2011) 
knodedisjoint hopconstrained survivable networks: polyhedral analysis and branch and cut
Diarrassouba, I.; Mahjoub, M.; Mahjoub, A. R.; Yaman, Hande (SpringerVerlag 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 knodedisjoint hopconstrained network design problem is to find a minimum weight subgraph of ... 
Multistage stochastic programming for demand response optimization
Şahin, Munise Kübra; Çavuş, Özlem; Yaman, Hande (Elsevier, 20200219)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 vehicleindexed flow formulation for the problem and then a relaxation obtained by aggregating ... 
pcenter problems
Çalık, Hatice; Labbé, M.; Yaman, Hande (Springer, 2015)A pcenter 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
RodríguezMartín, I.; SalazarGonzález, 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 ... 
A stochastic programming approach for Shelter location and evacuation planning
Bayram, V.; Yaman, Hande (EDP Sciences, 2018)Shelter location and traffic allocation decisions are critical for an efficient evacuation plan. In this study, we propose a scenariobased twostage stochastic evacuation planning model that optimally locates shelter sites ...
