a new secondary goal in dea cross-efficiency evaluation

Cross-efficiency evaluation in data envelopment analysis (dea) is a useful tool in evaluating the performance of decision-making units (dmus). the main idea of cross-efficiency is to use data envelopment analysis in peer evaluation, instead of only a self-evaluation. a factor that possibly reduces the usefulness of the cross-efficiency evaluation method is that the cross efficiency scores may not be unique due to the presence of alternate optima. as a result, it is recommended that secondary goals be introduced in cross-efficiency evaluation. in this paper we propose a new approach to the cross-efficiency evaluation with introduce new secondary goals. numerical examples are provided to illustrate effectiveness the proposed models.
