  • Centralized Cost Efficiency DEA Models 

    Rahmani Parchikolaei, B. (Science and Research Branch, Islamic Azad Universityدانشگاه آزاد اسلامی واحد علوم و تحقیقات, 2017-05-01)
    Cost efficiency measures the cost of resource by output production. While conventional cost efficiency models set targets separately for each DMU, There are cases where the Central decision making is seeking the above ...

  • Bank branches efficiency assessment using dynamic data envelopment analysis approach to SBM 

    Shafiee, M. (Science and Research Branch, Islamic Azad Universityدانشگاه آزاد اسلامی واحد علوم و تحقیقات, 2017-05-01)
    A new approach or model to the dynamic DEA, referred to as the adjusted dynamic DEA, is proposed in this study. Adjusted dynamic DEA optimizes the production activity of DMUs by introducing adjustment variables to modify ...
