摘要

During efficiency evaluating by DEA, the inputs and outputs of DMUs may be intervals because of insufficient information or measure error. For this reason, interval DEA is proposed. To make the efficiency scores more discriminative, this paper builds an Interval Modified DEA (IMDEA) model based on MDEA.Furthermore, models of obtaining upper and lower bounds of the efficiency scores for each DMU are set up.Based on this, the DMUs are classified into three types. Next, a new order relation between intervals which can express the DM' s preference to the three types is proposed. As a result, a full and more eonvietive ranking is made on all the DMUs. Finally an example is given.
