摘要：
One of the most important information given by DEA models is the cost and revenue efficiency of decision making units (DMUs). Cost efficiency is defined as the ratio of minimum costs to current costs, while revenue efficiency is defined as the ratio of maximum revenue to current revenue of the DMU. This paper aims to create models for the estimation of cost and revenue efficiency, with particular attention being paid to ratio DEA (DEA-R) models. This group of models eliminates some of the disadvantages associated with standard DEA models. The main contribution is the formulation of linear models for cost and revenue efficiency based on DEA-R models. The results given by the new models, as well as by the standard models are compared to a real data set the evaluation of 21 medical centers in Taiwan. (C) 2014 Elsevier Ltd. All rights reserved.
