Abstract

 The data envelopment analysis model (DEA) is the appropriate approach in measuring the EFFICIENCY of corporation, while in this model the decision maker is unable to enter the risk condition and the time factors in the results. On the order hand, in the agricultural investigations, the decision maker faces the risk condition and productivity problem. Basically the interval data envelopment analysis (IDEA) is a useful instrument in measuring the EFFICIENCY of several corporations with attention to risk condition and imprecise data, when also WINDOW DEA prepares feasibility calculation of productivity. In this study, with taking advantage from IDEA and WINDOW DEA techniques, the technical EFFICIENCY of important provinces in production of WHEAT crop is determined. The results show that among the selected provinces during period 1999-2004 Khoozestan has the highest ranking in productivity whereas Hamadan and East Azarbaijan have the lowest in their agricultural sectors. Also with attention to risk factor, Fars has the highest ranking in EFFICIENCY while Kordestan has the lowest in farming WHEAT.
