New method ranks efficient decision-making units for better resource allocation.
The article introduces a new method for ranking efficient decision-making units (DMUs) using data envelopment analysis (DEA). The researchers aim to address the issue of basic DEA models giving the same efficiency score to some DMUs. By incorporating the super efficiency technique and Euclidean norm, the proposed model can rank extreme efficient DMUs more accurately. This approach overcomes limitations of existing methods and provides a linear model to approximate the nonlinear one.
