Background and objectives: In this study, due to increasing of cardboard and paper products demand and consumption in Iran and also the important role of Mazandaran Wood and Paper Industries Company as a great supplier of paper products, the relative performance of the production units of this company was measured.
Materials and methods: In order to do this research, required data for a period of 6 years (2005 up to 2010) and 6 production units was collected form the company financial balance sheets. Due to the importance of this company, dual input- oriented data envelopment analysis models was used to measure its efficiency.
Results: The results indicated that this company in some production units (such as: newspaper, white kraft liner and fluting line 1) had a good efficiency score (%100 efficient or score 1). But, according to the input-oriented sample of these models and scale efficiency model (SE), the rest of production units were inefficient.
Conclusion: Hence, this company must reduce its consumption of finical inputs (similar to efficient units) until it increases its scale efficiency of production units and profitability.
