يك مدل شبه DEA براي اندازه گيري كارآيي تجمعي و كارآيي مولفه اي

DEA -Line model to determine aggregate and component efficiency

In many real application of DEA, the model presented, are designed to obtain an aggregatete efficiency score. However there are situations that the decision making units can be separated into different components in which each component consumes inputs to produce outputs. In this case some of inputs are shared among components. In this paper, we present a DEA - like to determine the aggregate efficiency of decision making units a companying with component measure.
