Overall Relative Efficiency in Network Data Envelopment Analysis

The Conventional network DEA in two-stage production process might not derive to the overall relative efficiency; hence we don’t achieve the real projection point becausethe projection point might not be efficient. Thus we need a model that give us relative efficiency measure. In this paper we present a model to obtain relative efficiency in network DEA.
