Meta Malmquist Index Based On Trade Offs Models in Data Envelopment Analysis

The Trade Offs approach is an advanced tool for the improvement of the discrimination of Data Envelopment Analysis (DEA) models, Meta Malmquist Index was defined by Maria Portella and et. al (2008). In this paper we compute the Meta Malmquist Index in Trade Offs model in DEA and we compare, obtaining results, of Meta Malmquist Index in different models of DEA, Variable Return to Scale (VRS), Constant Return to Scale (CRS) and Trade Offs (T-O). Numerical example is given for the purpose of illustration and we will show the management science is effective on efficiency of Decision Making Units (DMUs). The main advantage this index is that, it is circular. [Paris Firoozi shahmirzadi, Gholamreza Jahanshahloo. Meta Malmquist Index Based On Trade Offs Models in Data Envelopment Analysis.
