Abstract: (103 Views)
Data envelopment analysis methods classify decision-making units into two groups: Efficient and inefficient. Therefore, a complete ranking of all DMUs is requested by most decision-makers. In this paper, the TOPSIS method is combined with one of the data envelopment analysis models with a set of common weights, and a new combined ranking method of TOPSIS and DEA with common weights is proposed for ranking efficient units, which not only incorporates the advantages of data envelopment analysis methods and the TOPSIS method, but also solves the problems that appear in previous methods. In addition, to avoid extreme or zero values in the input and/or output weights, we include the coefficient of variation (CV) in our proposed model. We compared the proposed model with a number of well-known ranking models and then used this model to rank 20 Iranian bank branches.
Keywords: Data Envelopment Analysis (DEA), Decision Making Unit (DMU), Positive Ideal Point, Negative Ideal Point, TOPSIS, Coefficient of Variation (CV).
