    • Gain-loss based convex risk limits in discrete-time trading 

      Pinar, M. C. (Springer -Verlag, 2011-08)
      We present an approach for pricing and hedging in incomplete markets, which encompasses other recently introduced approaches for the same purpose. In a discrete time, finite space probability framework conducive to ...
    • Gain-loss pricing under ambiguity of measure 

      Pınar, M. Ç. (E D P Sciences, 2010)
      Motivated by the observation that the gain-loss criterion, while offering economically meaningful prices of contingent claims, is sensitive to the reference measure governing the underlying stock price process (a situation ...
    • The general behavior of pull production systems: the allocation problems 

      Kırkavak, N.; Dinçer, C. (Elsevier, 1999)
      The design of tandem production systems has been well studied in the literature with the primary focus being on how to improve their e ciency. Considering the large costs associated, a slight improvement in e ciency can ...
    • A general theory on spectral properties of state-homogeneous finite-state quasi-birth-death processes 

      Fadıloğlu, M. M.; Yeralan, S. (Elsevier, 2001)
      In this paper a spectral theory pertaining to Quasi-Birth–Death Processes (QBDs) is presented. The QBD, which is a generalization of the birth–death process, is a powerful tool that can be utilized in modeling many stochastic ...
    • Generalized column generation for linear programming 

      Oğuz, O. (Institute for Operations Research and the Management Sciences (INFORMS), 2002)
      Column generation is a well-known and widely practiced technique for solving linear programs with too many variables or constraints to include in the initial formulation explicitly. Instead, the required column information ...
    • Generalized second price auction is optimal for discrete types 

      Bayrak, H. I.; Pınar, M. Ç. (Elsevier, 2016)
      We prove that a variant of the second price auction for the sale of a single good through a Bayesian incentive compatible mechanism that maximizes expected revenue of the seller is optimal when the type space is discrete. ...
    • Generating facets for the independence system 

      Fouilhoux, P.; Labbé, M.; Mahjoub, A. R.; Yaman, H. (Society for Industrial and Applied Mathematics, 2009)
      In this paper, we present procedures to obtain facet-defining inequalities for the independence system polytope. These procedures are defined for inequalities which are not necessarily rank inequalities. We illustrate the ...
    • Generating robust and stable schedules in a single machine environment 

      Gören, Selçuk; Sabuncuoğlu, İhsan (IIE, 2004)
      Scheduling is a decision making process that concerns with allocation of limited resources (machines, material handling equipment, operators, tools, etc.) to competing tasks (operations of jobs) over time with the goal of ...
    • Generating short-term observation schedules for space mission projects 

      Aktürk, M. S.; Kılıç, K. (Kluwer Academic Publishers, 1999)
      In this paper, we propose a new dispatching rule and a set of local search algorithms based on the filtered beam search, GRASP and simulated annealing methodologies to construct short-term observation schedules of space ...
    • A genuinely polynomial primal simplex algorithm for the assignment problem 

      Akgül, M. (Elsevier, 1993)
      We present a primal simplex algorithm that solves the assignment problem in 1 2n(n+3)-4 pivots. Starting with a problem of size 1, we sequentially solve problems of size 2,3,4,...,n. The algorithm utilizes degeneracy by ...
    • 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.
    • Global manufacturing strategy 

      Dinçer, M. Cemal; Verter, Vedat (Springer-Verlag, 1995)
    • 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 ...
    • 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)
