Hybrid model in network DEA

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