There are several approaches for increasing the competitive power of an organization. However, in some cases, some of the approaches are contradictory. Improving efficiency and productivity is one of the best approaches to solve these conflicts. In this research, we have measured the efficiency of five active iron mines during 2008 - 2011, using Data Envelopment Analysis (DEA) method and the efficient and inefficient units were determined. Due to the limited number of studied mines compared with the total amount of inputs and outputs, the discrimination could happen. Thus, we have used Anderson-Peterson (AP) approaches as a complementary method for DEA classic models, in order to determine productive units' final ranking. Based on the results obtained, Mishduvan mine has the highest rank and the highest amount of efficiency during 2009 - 2011.
