Abstract— Data envelopment analysis (DEA) is a nonparametric method in Operations Research and Economics for measuring the relative efficiency of peer decision making units (DMUs) that have multiple inputs and outputs. In many situations, DMUs can have a two-stage structure where the first stage uses inputs to produce outputs (called intermediate measures) that then become the inputs to the second stage. In recent studies on two-stage production processes, authors used the radial DEA models to… CONTINUE READING
