EVALUATING THE PERFORMANCE AND RANKING OF THE PROVINCES OF THE COUNTRY IN BARLEY PRODUCTION USING THE DATA ENVELOPMENT ANALYSIS WITH REGARD TO WEIGHT RESTRICTIONS

Abstract

Wheat and barleyhave long been involved and blended into thedaily livesof the
people,directlyorindirectly. Breadis the staplenourishment of all inhabitants of the world
including Iranians. Therefore, it provision is among thetop priorities ofhuman societies. Given
the importance ofbarleyin Iran, thispaper has discussed the performance and ranking evaluation
of the provinces of the country in barley production using the data envelopment analysis with
regard tohomogeneousallocationof the weights. The advantage of thismethodover the
othermethods ofweightrestrictionis that it has no effecton thesolution space of the
issue.Theobtained resultscan be used as a reference in evaluating performance and planning for
achieving higher efficiency in Barleyproduction inthe provinces of the country. Thispaperhas not
only calculated the efficiency using SWAT model but also calculated the efficiency of the units
usingdata envelopment analysisin classicalmode in order to determinethe ability ofthe modelin
distinguishing betweenthe units.
