Wood panel manufacturing is one of the important sectors in Iranian wood industry. The sector faces serious
limitations in production technology and raw materials. So the performance of 10 firms of Iranian wood panels
industry was evaluated. A DEA window analyses with a free oriented slack-based measure model (SBM) were
performed based on financial data collected for the period of 5 years (2002 to 2006). The (firms) decision-making
units were ranked based on average of efficiency scores and determination of the trends of their behaviors and
stability of performances. The results of estimated efficiency score showed that all decision-making units (DMUs)
in wood panel sector were stable (considering low standard deviation). But their trends and stability behaviors
showed that almost half of decision-making units were positive. The difference of total range and the efficiency
score average showed that many DMUs still were inefficient and reflect a fluctuation in efficiency score.
