    • Continuous models combining slacks-based measures of efficiency and super-efficiency
    Authors: Vicente J., Bolós; Rafael, Benítez; Vicente, Coll-Serrano;  Advisor: -;  Co-Author: - (2023)

    In the framework of data envelopment analysis (DEA), Tone (Eur J Oper Res 130(3):498–509, 2001) introduced the slacks-based measure (SBM) of efficiency, which is a nonradial model that incorporates all the slacks of the evaluated decision-making units (DMUs) into their efficiency scores, unlike classical radial efficiency models. Next, Tone (Eur J Oper Res 143(1):32–41, 2002) developed the SBM super-efficiency model in order to differentiate and rank efficient DMUs, whose SBM efficiency scores are always 1.
