A METHOD FOR CLASSIFICATION OF DECISION-MAKING UNITS USING DEA AND INVERTED DEA WITH SCALE EFFICIENCY

摘要

In order to find decision-making units (DMUs) with singular managerial operations, a method of classifying DMUs by integrating data envelopment analysis (DEA) and inverted DEA (IDEA) has been developed. In this article, we propose a modification of the method incorporating scale efficiency of each DMU. We report some numerical results, which show that this method can accurately evaluate DMUs even under disadvantageous conditions.
