Unlike the traditional Data Envelopment Analysis (DEA) approach, the efficiency of network structures depends on the performance of their internal components. This paper proposes a novel approach for evaluating the performance of network structures by employing a bounded adjusted measure (BAM) non-radial model. This method identifies all inefficiencies arising from intermediate variables. Moreover, the study incorporates intermediate products in assessing both overall efficiency and the efficiency of sub-sectors, thereby enhancing the model’s discriminatory power. Through six different scenarios and by developing multiple production possibility sets based on the concept of controllability, the study determines the optimal values for the links connecting the sections of a network. A key advantage of this method is its ability to decompose overall efficiency into the efficiencies of its constituent sub-sectors. Finally, to demonstrate the applicability of the proposed method, a practical example is provided to illustrate and compare the outcomes of the different scenarios.
