Abstract

In many DATA ENVELOPMENT ANALYSIS (DEA) problems, Decision Making Units (DMUs) are managed under supervision of a unified system. For instance, all universities of a country are under supervision of education ministry. Thus, investments for passing from an unsuitable situation to a desirable form are done by such a system. In this situation, managers would like to know which approach is the closest to improve their system. The purpose of this paper is to present an approach in which the inefficient DMUs achieve to an efficient situation by least possible changes. For this end, in order to convert an inefficient DMU to efficient DMU, the INPUTs reduction of each inefficient DMU is studied. Afterwards, using an aggregating preference ranking problem, the INPUTs are ranked based on their closeness to the efficiency frontier. Priority of a DMU to other means that decision maker should invest on it more than other to achieve an efficient System.
