An application of IDEA to wheat farming efficiency

摘要: Data Envelopment Analysis (DEA) is a nonparametric approach to evaluating the relative efficiency of decision making units (DMUs) that use multiple inputs produce outputs. An assumption underlying DEA all data assume form specific numerical values. In some applications, however, may be imprecise. That is, input and output cannot exactly obtained due existence uncertainty. They are only known lie within specified intervals. A model with imprecise or, more compactly, an Imprecise (IDEA) proposed in this article evaluate for each DMU. The illustrated application Iranian wheat producer provinces.
