  • The Uniqueness of the Overall Assurance Interval for Epsilon in DEA Models by the Direction Method 

    Mehrabian, S. (Science and Research Branch, Islamic Azad Universityدانشگاه آزاد اسلامی واحد علوم و تحقیقات, 2015-08-01)
    The role of non-Archimedean  in the DEA models has been clarified, so that the associatedlinear programs can be infeasible (for the multiplier side) and unbounded (for theenvelopment side) with an unsuitable ...

  • Introducing a secondary goal for evaluating DMUs by cross efficiency in data envelopment analysis 

    Mehrjoo, R.؛ .Shoja, N (Science and Research Branch, Islamic Azad Universityدانشگاه آزاد اسلامی واحد علوم و تحقیقات, 2015-08-01)
    One way to rank DMUs in DEA is the cross efficiency method. In this method, the efficiencyof each DMU is calculated by other DMUs optimum weights, which makes the ranking moreacceptable for managers. Existing ...

  • Classifying Flexible Factors Using Fuzzy Concept 

    Saati, S.؛ Imani, N. (Science and Research Branch, Islamic Azad Universityدانشگاه آزاد اسلامی واحد علوم و تحقیقات, 2015-08-01)
    In Data Envelopment Analysis (DEA), it is assumed that the role of each factor is known asinput or output. However, in some cases, there are shared factors that their input versusoutput status is not clearly ...

  • Productivity changes of units: A directional measure of cost Malmquist index 

    Tohidi, G.؛ Tohidnia, S. (Science and Research Branch, Islamic Azad Universityدانشگاه آزاد اسلامی واحد علوم و تحقیقات, 2015-08-01)
    This study examines the productivity changes of decision making units in situation whereinput price vectors are varying between them and inputs are heterogeneous; that is a noncompetitivemarket. We present a ...
