      Selecting process of a machine tool has been very important issue for companies for years, because the improper selection of a machine tool might cause of many problems affecting negatively on productivity, precision, ...
    • A Hierarchical Planning Approach for a Production-distribution System 

      Özdamar, Linet; Aktin, Ayşe Tülin (TAYLOR & FRANCIS LTD, ONE GUNPOWDER SQUARE, LONDON EC4A 3DE, ENGLAND, 1999-11-10)
      A production-distribution model involving production and transportation decisions in a central factory and its warehouses is developed. The model is based on the operating system of a multi-national company producing ...
    • An intelligent approach to ERP software selection through fuzzy ANP 

      Özdemir, Rifat Gürcan; Ayağ, Zeki (TAYLOR & FRANCIS LTD, 4 PARK SQUARE, MILTON PARK, ABINGDON OX14 4RN, OXON, ENGLAND, 2007)
      During the implementations of enterprise resource planning (ERP) systems, most companies have experienced some problems, one of which is how to determine the best ERP software satisfying their needs and expectations. Because ...
    • An Intelligent Approach To Machine Tool Selection Through Fuzzy Analytic Network Process 

      Ayağ, Zeki; Özdemir, Rifat Gürcan (Springer, Van Godewijckstraat 30, 3311 Gz Dordrecht, Netherlands, 2011-04)
      In this study, we utilize analytic network process (ANP), a more general form of AHP, for justifying stand-alone machine tools out of available alternatives in market due to the fact that AHP cannot accommodate the variety ...
    • Multi Objective New Product Development In Bakery Production Under Fuzzy Demand Parameters 

      Özdemir, Rifat Gürcan; Çiçek, Burçin; Özenç, Derya (Ios Press, Nieuwe Hemweg 6B, 1013 Bg Amsterdam, Netherlands, 2010)
      This paper deals with the problem of multi objective new product development and its solution with an intelligent approach. The proposed approach uses fuzzy parameters for economic analysis and combines a multi-criteria ...
    • On The Evolution Of Anomalous X-Ray Pulsars And Soft Gamma-Ray Repeaters Wıth Fall Back Disks 

      Ertan, Ünal; Ekşi, Kazım Yavuz; Erkut, Mehmet Hakan; Alpar, Mehmet Ali (Iop Publishing Ltd, Temple Circus, Temple Way, Bristol Bs1 6Be, England, 2009-09-10)
      We show that the period clustering of anomalous X-ray pulsars (AXPs) and soft gamma-ray repeaters (SGRs), their X-ray luminosities, ages, and statistics can be explained with fall back disks with large initial specific ...
    • Raman Micro-Spectroscopic Analysis of Cultured HCT116 Colon Cancer Cells in The Presence of Roscovitine

      Raman micro-spectroscopic analysis of cultured HCT116 colon cancer cells in the presence of roscovitine, [seliciclib, 2-(1-ethyl-2-hydroxy-ethylamino)-6-benzylamino-9-isopropylpurine], a promising drug candidate in cancer ...
    • Solution of counter diffusion problem with position dependent diffusion coefficent by using variational methods 

      Yüksek, Kemal; Koca, Yeliz; Sadıkoğlu, Hasan (ELSEVIER SCIENCE BV, PO BOX 211, 1000 AE AMSTERDAM, NETHERLANDS, 2009-10-15)
      Unsteady state counter diffusion problem with position dependent diffusion coefficient can be modeled using Fick's second law. A mathematical model was constructed and solved to quantitatively describe the dynamic behavior ...
