CLASSIFYING INTERVAL DATA IN DEA

In some applications, data of Decision Making Units (DMUs) are interval and flexible. To evaluate these DMUs we have to determine the input/output status of these data. This paper presents a method to classify bounded data in Data Envelopment Analysis (DEA). To this end, the current paper proposes a bi-level mathematical programming model and determines the input/output statue of interval flexible such that theefficiency of them are maximized.
