On setting scale efficient targets in data envelopment analysis

This paper discusses theoretical and practical aspects of setting scale efficient targets in DEA. We provide new models for setting scale efficient targets for overall inefficient DMUs which overcome some of the technical problems in the commonly used methods of setting a target. The new targets are shown to be the same under input minimisation and output maximisation criteria. Practical problems of implementing the targets can be addressed by an entirely different approach which is also considered.
