Determining efficiency and ranking of production lines are important issues in operations management. In this paper, we calculate the efficiency of production lines using network data envelopment analysis (NDEA) model in the presence of desirable and undesirable outputs. However, in NDEA several production lines may become efficient which makes ranking impossible. For the first time, maximal balance index and NDEA are combined to rank production lines. A case study determines efficiency scores of seven Iranian factories. Case study shows advantage of our model over previous ones.
