A Method for Finding Most Efficient Decision Making Unit with Interval Data in Data Envelopment Analysis

One of the major issues and application in DEA is obtaining the most efficient decision making unit (DMU). In fact, decision makers are trying to consider the most efficient DMU in several models. Hence they can achieve most efficient unit of the existing units. In some cases, the data are indefinite and we have disposal their indefinite values so in this paper we are obtaining the most efficient unit when the data are interval.
