Abstract
In this paper, we formulate the DEA model with interval efficiency, there exist two phases of efficiency evaluation with respect to the upper limit and the lower limit. From these viewpoints, we can define two extreme points of efficiency. As a result, an interval efficiency for each DMU cam be obtained. We also formulate the interval cross-efficiency.
