Traditional DEA models deal with measurements of relative eciency of
DMUs regarding multiple - inputs VS. multiple-outputs. One of the drawbacks
of these model is the neglect of intermediate products or linkong activities. Af-
ter 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 eciency of decision making units (DMU) and we show
this model with an example.
