DEA Model For Two-Stage Systems With Interval Data

Data Envelopment Analysis (DEA) aims at assessing the relative efficiency of a number of comparable operating units. In conventional DEA, efficiencies are arranged as a linear order, but in interval DEA, Decision Making Units (DMUs) cannot be easily evaluated and arranged using the calculated efficiency scores. In this paper, we present a relative efficiency measurement for two-stage evaluation with interval data.
