Hybrid model in network DEA

Abstract

Traditional DEA models deal with measurements of relative e ciency of<br />DMUs regarding multiple - inputs VS. multiple-outputs. One of the drawbacks<br />of these model is the neglect of intermediate products or linkong activities. Af-<br />ter pointing out needs for inclusion of them to DEA models. We propose hybrid<br />model that can deal with intermediate products formally using this model we<br />can evaluate divisional e ciency of decision making units (DMU) and we show<br />this model with an example.
