    • A GIS ‐ based framework for hazardous materials transport risk assessment 

      Verter, V.; Kara, B. Y. (Wiley-Blackwell Publishing, 2001)
      This article presents a methodology for assessment of the hazardous materials transport risk in a multicommodity, multiple origin – destination setting. The proposed risk assessment methodology was integrated with a ...
    • A global error bound for quadratic perturbation of linear programs 

      Pınar, M. C. (Elsevier, 2002)
      We prove a global error bound result on the quadratic perturbation of linear programs. The error bound is stated in terms of function values.

    • 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 ...
    • Hard turning with variable micro-geometry PcBN tools 

      Özel, T.; Karpat, Y.; Srivastava, A. (Elsevier, 2008)
      This paper presents investigations on hard turning with variable edge design PcBN inserts. Turning of hardened AISI 4340 steel with uniform and variable edge design PcBN inserts is conducted, forces and tool wear are ...
    • Hazard change point estimation 

      Gürler, Ülkü (John Wiley & Sons, 2006)
    • Hazardous waste management problem: the case for incineration 

      Emek, E.; Kara, B. Y. (Elsevier, 2007)
      We define the hazardous waste management problem as the combined decisions of selecting the disposal method, siting the disposal plants and deciding on the waste flow structure. The hazardous waste management problem has ...
    • Hazardous waste management system design under population and environmental impact considerations 

      Yilmaz, O.; Kara, B. Y.; Yetis, U. (Academic Press, 2017)
      This paper presents a multi objective mixed integer location/routing model that aims to minimize transportation cost and risks for large-scale hazardous waste management systems (HWMSs). Risks induced by hazardous wastes ...
    • Health network mergers and hospital re-planning 

      Güneş, E. D.; Yaman, H. (Palgrave Macmillan Ltd., 2010)
      This paper presents an integer programming formulation for the hospital re-planning problem which arises after hospital network mergers. The model finds the best re-allocation of resources among hospitals, the assignment ...
    • Hedging production schedules against uncertainty in manufacturing environment with a review of robustness and stability research 

      Sabuncuoglu, I.; Goren, S. (Taylor & Francis, 2009)
      Scheduling is a decision-making process that is concerned with the allocation of limited resources to competing tasks (operations of jobs) over a time period with the goal of optimising one or more objectives. In theory, ...
    • A heuristic procedure for a single-item dynamic lot sizing problem 

      Benli, O. S.; Sabuncuoglu, I.; Tufekci, S. (Pergamon Press, 1988)
      An O(T) heuristic proceudre for a single-item dynamic lot sizing problem is introduced in this paper. The algorithm tries to establish the regeneration points of the problem whether either the production or the beginning ...
    • Hibernation durations for chain of machines with maintenance under uncertainty 

      Doğramacı, Ali (Springer, 2005)
      Maintenance of a machine and its replacements by newer ones in the course of a predetermined planning horizon with fixed intermediate dates for potential replacement opportunities is considered. Using the Kamien-Schwartz ...
    • The hierarchical hub median problem with single assignment 

      Yaman, H. (Elsevier, 2009)
      We study the problem of designing a three level hub network where the top level consists of a complete network connecting the so-called central hubs and the second and third levels are unions of star networks connecting ...
    • A hierarchical model for the cell loading problem of cellular manufacturing systems 

      Aktürk, M. S.; Wilson, G. R. (Taylor & Francis, 1998)
