Some Properties of Cost Efficiency Measures in DEA

چکیده مقاله

Data Envelopment Analysis (DEA) evaluate the performance of some homogeneous Decision Making Units (DMUs) with multiple inputs-multiple outputs via assessing their (technical) efficiency measures. However, when unit costs/prices are available, it is important to take them into account in the procedure of evaluating DMUs. In this paper we present some DEA models assessing cost efficiency measure and then investigate some properties of the obtained measures
