      Keskintürk, Timur; Yildirim, Mehmet Bayram (2011-05)
      In this paper, we analyze a distribution problem at a bakery company in Istanbul, Turkey. The bakery wants to distribute products with the available fleets of trucks, while maintaining balance in workload between different ...
    • A nonlinear approach for integrated marketing-economic production quantity problem 

      Ghazi-Nezami, Farnaz; Yildirim, Mehmet Bayram (2010-12)
      Pricing is a key activity in determining any firm's profit in a supply chain due to the competitive nature of markets. Consequently, modeling the relation between marketing and manufacturing departments in a manufacturing ...
    • Acoustical properties of electrospun nanofibers for aircraft interior noise reduction 

      Asmatulu, Ramazan; Khan, Waseem Sabir; Yildirim, Mehmet Bayram (2009)
      Electrospun micro and nanofibers produced via electrospinning method were used for the sound absorption purposes. Polymers were initially dissolved in dimethyleformamide (DMF) or ethanol with a ratio of 80:20 and ...
    • Active learning in supply chain management course 

      Ghazi-Nezami, Farnaz; Yildirim, Mehmet Bayram (2015-06)
      This paper presents an active learning approach implemented in the Supply Chain Management (SCM) course. In this course, the fundamentals of supply chain and logistics, drivers of supply chain performance and analytical ...
    • Computational methods for congestion toll pricing models 

      Hearn, Donald W.; Yildirim, Mehmet Bayram; Ramana, M. V.; Bai, L. H. (IEEE Intelligent Transportation Systems, 2001-08)
      In earlier work a toll pricing framework for congestion pricing has been developed for both fixed and elastic demand traffic assignment models as an alternative to traditional marginal social cost pricing. Within the ...
    • Energy consumption of VA hospital CT scans 

      Esmaeili, Mohammad Amin; Jahromi, Ashkan S.; Twomey, Janet M.; Yildirim, Mehmet Bayram; Overcash, Michael; Elsken, Tyson; Dominquez, Fernando; Thomas, Nicholas; Mcadam, Ashlee (IEEE, 2011-05)
      The United States healthcare spending was about $7,681 per resident and accounted for 16.2% of the nation's GDP in 2008 and rose to compromise about 18% of the nation's GDP by 2010. As healthcare sector continues to grow ...
    • Environmental impacts of healthcare services: delivery of x-ray services 

      Esmaeili, Mohammad Amin; Twomey, Janet M.; Yildirim, Mehmet Bayram; Overcash, Michael; Jahromi, Ashkan S.; Thomas, Nicholas; Mcadam, Ashlee; Dominquez, Fernando (IEEE, 2011-05)
      THE healthcare sector of the U.S rose to compromise about 18% of the nation's GDP in 2010. In meeting patient needs healthcare organizations spend nearly $8.8 billion each year on energy. To achieve energy reduction, the ...
    • A framework to minimize total energy consumption and total tardiness on a single machine 

      Mouzon, Gilles C.; Yildirim, Mehmet Bayram (Wichita State University. Graduate School., 2008-04-25)
      A great amount of energy is wasted in industry by machines which stay idle due to underutilization. A way to avoid consuming the wasted energy is to incorporate energy consumption into consideration while making the ...
    • Genetic algorithm to solve a multi-objective scheduling problem 

      Mouzon, Gilles C.; Yildirim, Mehmet Bayram (Wichita State University. Graduate School., 2007-04-27)
      Energy is expensive and a potential way to reduce energy consumption may be through using intelligent scheduling techniques. In this paper, we propose a genetic algorithm to solve a single machine scheduling problem where ...
