Özet: This paper proposes two data envelopment analysis (DEA) cross efficiency models for selecting the most efficient alternatives in manufacturing technology. The cross efficiency evaluation (CEE) method which is developed as a contribution to the classical Data Envelopment Analysis (DEA) is a method successively used in the ranking problems. In its original, the CEE method includes the efficiency evaluations made use for the reusage of optimal weights in the other DMUs obtained for a DMU by the classical DEA. Since the optimal weights in the classical DEA solutions have usually multiple solutions, this reduces the usefulness of CEE method. This study suggests new methods for the second stage of CEE method to remove the question of multiple optimal weights. A numerical example illustrates the model, and an application in technology selection with multi-inputs/multi-outputs shows the usefulness of the proposed approaches.
