A Hybrid Measure of Efficiency for Decision Making Uints with Network Structure

Because of characterization of input and output items there are two types of measurements in Data Envelopment Analysis (DEA). These measurements are radial and non-radial. Network Data Envelopment Analysis (NDEA) models deal with measurements of relative efficiency of DMUs which their outputs change radial or non-radial. But, in some situations in a network some inputs(outputs) are radial and the others are non-radial. So, this paper proposes a hybrid network DEA model, which can deal with intermediate products formally. Using this model we can evaluate efficiencies of DMUs with radial and nonradial data.
