    • Age-based vs. stock level control policies for a perishable inventory system 

      Tekin, E.; Gürler Ü.; Berk, E. (2001)
      In this study, we investigate the impact of modified lotsize-reorder control policy for perishables which bases replenishment decisions on both the inventory level and the remaining lifetimes of items in stock. We derive ...
    • The effects of structural characteristics of explanations on use of a DSS 

      Gönül, M. S.; Önkal D.; Lawrence, M. (Elsevier, 2006)
      Research in the field of expert systems has shown that providing supporting explanations may influence effective use of system developed advice. However, despite many studies showing the less than optimal use made of DSS ...
    • Evaluating predictive performance of judgemental extrapolations from simulated currency series 

      Pollock, A. C.; Macaulay, A.; Önkal-Atay, D.; Wilkie-Thomson, M. E. (Elsevier, 1999)
      Judgemental forecasting of exchange rates is critical for financial decision-making. Detailed investigations of the potential effects of time-series characteristics on judgemental currency forecasts demand the use of ...
    • A game theoretical modeling and simulation framework for the integration of unmanned aircraft systems in to the national airspace 

      Musavi N.; Tekelioglu K.B.; Yildiz Y.; Gunes K.; Onural D. (American Institute of Aeronautics and Astronautics Inc, AIAA, 2016)
      The focus of this paper is to present a game theoretical modeling and simulation frame- work for the integration of Unmanned Aircraft Systems (UAS) into the National Airspace system (NAS). The problem of predicting the ...
    • Guessing with lies 

      Arikan, E.; Boztaş, S. (2002)
      A practical algorithm was obtained for directly generating an optimal guessing sequence for guessing under lies. An optimal guessing strategy was defined as one which minimizes the number of average number of guesses in ...
    • Incorporating just-in-time into a decision support system environment 

      Oǧuz, Ceyda; Dinçer, Cemal (Elsevier BV, 1991)
      In this paper, a Decision Support System is proposed for a Just-In-Time production system. The Decision Support System includes three components: database, model base, and interface. The database contains the predefined ...
    • Inventory control under substitutable demand: A stochastic game application 

      Avsşr, Z. M.; Baykal-Gürsoy, M. (John Wiley & Sons, 2002)
      Substitutable product inventory problem is analyzed using the concepts of stochastic game theory. It is assumed that there are two substitutable products that are sold by different retailers and the demand for each product ...
    • Investments viewed as growth processes 

      Doğrusöz, H.; Karabakal, N. (Taylor & Francis, 1995)
      For modeling investment decision situations, we present a mathematical basis that views the cash flow sequences as growth processes. We first emphasize the pedagogical value of the basic model by showing that all traditionally ...
    • Market-driven approach based on Markov decision theory for optimal use of resources in software development 

      Noppen, J.; Aksit, M.; Nicola, V.; Tekinerdogan, B. (Institution of Engineering and Technology, 2004)
      Changes in requirements may have a severe impact on development processes. For example, if requirements change during the course of a software development activity, it may be necessary to reschedule development activities ...
    • Match-up scheduling under a machine breakdown 

      Aktürk, M. S.; Görgülü, E. (Elsevier, 1999)
      When a machine breakdown forces a modified flow shop (MFS) out of the prescribed state, the proposed strategy reschedules part of the initial schedule to match up with the preschedule at some point. The objective is to ...
    • A new lower bounding scheme for the total weighted tardiness problem 

      Selim Akturk, M.; Bayram Yildirim, M. (1998)
      We propose a new dominance rule that provides a sufficient condition for local optimality for the 1∥Σw1Ti problem. We prove that if any sequence violates the proposed dominance rule, then switching the violating jobs either ...
    • Order of limits in reputations 

      Dalkıran, N. A. (Springer, 2016)
      The fact that small departures from complete information might have large effects on the set of equilibrium payoffs draws interest in the adverse selection approach to study reputations in repeated games. It is well known ...
    • Qualitative test-cost sensitive classification 

      Cebe, M.; Gunduz Demir, C. (Elsevier BV, 2010)
      This paper reports a new framework for test-cost sensitive classification. It introduces a new loss function definition, in which misclassification cost and cost of feature extraction are combined qualitatively and the ...
    • Qualitative test-cost sensitive classification 

      Cebe, Mümin (Bilkent University, 2008)
      Decision making is a procedure for selecting the best action among several alternatives. In many real-world problems, decision has to be taken under the circumstances in which one has to pay to acquire information. In ...
    • Satisfying due-dates in a job shop with sequence-dependent family set-ups 

      Taner, M. R.; Hodgson, T. J.; King, R. E.; Thoney, K. A. (Taylor & Francis, 2003)
      This paper addresses job shop scheduling with sequence dependent family set-ups. Based on a simple, single-machine dynamic scheduling problem, state dependent scheduling rules for the single machine problem are developed ...
    • Test-cost sensitive classification based on conditioned loss functions 

      Cebe, Mümin; Gündüz-Demir, Çiğdem (Springer, 2007-09)
      We report a novel approach for designing test-cost sensitive classifiers that consider the misclassification cost together with the cost of feature extraction utilizing the consistency behavior for the first time. In this ...
    • Voting as validation in robot programming 

      Utete, S. W.; Barshan, B.; Ayrulu, B. (Sage Publications Ltd., 1999-04)
      This paper investigates the use of voting as a conflict-resolution technique for data analysis in robot programming. Voting represents an information-abstraction technique. It is argued that in some cases a voting approach ...
