goal study evaluate sustainability efficiency corn production regard energy consumption fars province southwest iran reach goal fuzzy modeling data envelopment analysis dea employed fuzzy model included three submodels assessed sustainability use energy inputs ie machinery fuel fertilizer chemical human power seed electricity dea models like ccr charnes cooper rhodes bcc banker charnes cooper sbm slack based measure applied assessment efficiency scores using nonhierarchical cluster analysis 89 farmers chosen two clusters including 47 42 farmers first second cluster respectively farmers cluster 2 used 44238235 mjha energy input 2500 mjha first cluster fuzzy modeling revealed sustainability indices higher first cluster however indices ranges low medium farmers representing current corn production system sustainable also dea models revealed first cluster also held efficient farmers since dea defines reference set efficient inefficient farmers follow lead inefficient farmers improve sustainability efficient ones therefore efficient inefficient farmers must change trends energy utilization approaching even sustainable production
