To measure the relative efficiency of multi-sector DMU’s, it is essential to focus on the activities which relate these sectors together.  The electrical firms or companies usually include different parts or sectors and focusing on the efficiency of each part enables us to evaluate the efficiency of the complex in a better way. In this paper, using the network DEA based on SBM approach we have measured the efficiency of electrical firms or companies in Iran.
