  • Backtracking and exchange of information: Methods to enhance a beam search algorithm for assembly line scheduling 

    Sabuncuoglu, I.; Gocgun, Y.; Erel, E. (Elsevier, 2008-05)
    Beam search (BS) is used as a heuristic to solve various combinatorial optimization problems, ranging from scheduling to assembly line balancing. In this paper, we develop a backtracking and an exchange-of-information ...
  • Effects of feedback on probabilistic forecasts of stock prices 

    Onkal, D.; Muradoglu, G. (Elsevier, 1995-06)
    This paper reports the results of an experiment in stock-price forecasting that investigated the effects of feedback on various dimensions of probability forecasting accuracy. Three types of feedback were used: (1) simple ...
  • A methodology for solving single-model, stochastic assembly line balancing problem 

    Sarin, S. C.; Erel, E.; Dar El, E. M. (Elsevier, 1999-10)
    In this paper, a methodology is developed to solve the single-model, stochastic assembly line balancing problem for the objective of minimizing the total labor cost and the expected incompletion cost arising from tasks ...
  • A note on price-volume dynamics in an emerging stock market 

    Basci, E.; Ozyildirim, S.; Aydogan, K. (Elsevier, 1996-03)
    We present a continuum economy with risk neutral agents having heterogeneous expectations and restricted short sales. A stochastic version of the model is also formulated and the resulting time series behavior of the ...
  • Binary integer formulation for mixed-model assembly line balancing problem 

    Gokcen, H.; Erel, E. (Elsevier, 1998-04-01)
    The assembly line balancing problem has been a focus of interest to the academicians of production/operations management for the last 40 years. Although there are numerous studies published on the various aspects of the ...
  • An Enlargement of the Notion of Consumer Vulnerability 

    Commuri, S.; Ekici, A. (Sage, 2008-06)
    Consumer vulnerability has long been an important issue in public policy and macromarketing. The focus of a special issue of the Journal of Macromarketing (vol. 26, issue 1) underscores this importance. The articles in ...
  • Market Reaction to Risky Banks: Did Generous Deposit Guarantee Change it? 

    Onder, Z.; Ozyildirim, S. (Elsevier, 2008-08)
    Turkey experienced a massive banking crisis in February 2001, resulting in the loss of more than a thousand managerial jobs and the closure of 21% of all bank branches in the market. In this paper, we study the behavior ...
  • Personal Lives? The Effects of nonwork behaviors on organizational image 

    Umphress, E. E.; Tihanyi, L.; Bierman, L.; Gogus, C. I. (Sage, 2013-08)
    Organizational leaders may respond to employee nonwork behaviors because of the possible influence on organizational image. We describe a typology of nonwork behaviors and discuss their potential implications for ...
  • Professional vs. amateur judgment accuracy: The case of foreign exchange rates 

    Onkal, D.; Yates, J. F.; Simga Mugan, C.; Oztin, S. (Elsevier, 2003-07)
    Highly knowledgeable people often fail to achieve highly accurate judgments, a phenomenon sometimes called the ‘‘processperformance paradox.’’ The present research tested for this paradox in foreign exchange (FX) rate ...
  • Performance Evaluation of Judgmental Directional Exchange Rate Predictions 

    Pollock, A. C.; Macaulay, A.; Thomson, M. E.; Onkal, D. (Elsevier, 2005-09)
    A procedure is proposed for examining different aspects of performance for judgemental directional probability predictions of exchange rate movements. In particular, a range of new predictive performance measures is ...
  • Joint economic design of EWMA control charts for mean and variance 

    Serel, D.; Moskowitz, H. (Elsevier, 2008-01-01)
    Control charts with exponentially weighted moving average (EWMA) statistics (mean and variance) are used to jointly monitor the mean and variance of a process. An EWMA cost minimization model is presented to design the ...
  • A multicriteria facility location model for municipal solid waste management in North Greece 

    Erkut, E.; Karagiannidis, A.; Perkoulidis, G.; Tjandra, S. A. (Elsevier, 2008-06-16)
    Up to 2002, Hellenic Solid Waste Management (SWM) policy specified that each of the country’s 54 prefectural governments plan its own SWM system. After 2002, this authority was shifted to the country’s 13 regions entirely. ...
  • Bayesian demand updating in lost sales newsvendor: a two moment approximation 

    Berk, E.; Gurler, U.; Levine, R. A. (Elsevier, 2007-10)
    We consider Bayesian updating of demand in a lost sales newsvendor model with censored observations. In a lost sales environment, where the arrival process is not recorded, the exact demand is not observed if it exceeds ...
  • The cost and risk impacts of rerouting railroad shipments of hazardous materials 

    Glickman, T. S.; Erkut, E.; Zschocke, M. S. (Elsevier, 2007-09)
    Rail shipments of hazardous materials expose the population near the routes to the possibility of an accident resulting in a spill. Rail routes are determined by economic concerns such as route length and the revenue ...
  • Cross cultural differences in materialism 

    Ger, G.; Belk, R. W. (Elsevier, 1996-02)
    Materialism was explored in twelve countries using qualitative data, measures of consumer desires, measures of perceived necessities, and adapted versions of the Belk (1985) materialism scales with student samples. The ...
  • The discourses of marketing and development: towards 'critical transformative marketing research' 

    Tadajewski, M.; Chelekis, J.; DeBerry Spence, B.; Figueiredo, B.; Kravets, O.; Nuttavuthisit, K.; Penazola, L.; Moisander, J. (Taylor and Francis, 2014-09)
    In order to understand the connection between development, marketing and transformative consumer research (TCR), with its attendant interest in promoting human well-being, this article begins by charting the links between ...
  • Does Backing Up Behavior Explain the Efficacy-Performance Relationship in Teams? 

    Porter, C. O. L. H.; Gogus, I.; Yu, R. C. F. (Sage, 2011-02-28)
    Although the relationship between collective efficacy beliefs and team performance has been well-documented, few studies have explored the causal mechanisms that might explain these effects. In the current study, the authors ...
  • Minimizing weighted mean absolute deviation of job completion times from their weighted mean 

    Erel, E.; Ghosh, J. B. (Elsevier, 2011-07-15)
    We address a single-machine scheduling problem where the objective is to minimize the weighted mean absolute deviation of job completion times from their weighted mean. This problem and its precursors aim to achieve the ...
  • Poverty in consumer culture: Towards a tranformative social representation 

    Hamilton, K.; Piacentini, M. G.; Banister, E.; Barrios, A.; Blocker, C. P.; Coleman, C. A.; Ekici, A.; Gorge, H.; Hutton, M.; Passerard, F.; Saatcioglu, B. (Routledge, 2014-10-20)
