Abstract:

In view of the insufficiency of cross evaluation model of DEA methods on the ranking of decision making units that multiple evaluation processes are needed for completely ranking, a ranking mechanism with the balance index model is analyzed, and concluded that the ranking result is more complete with this model having been used. Based on these a new DEA ranking model, the comprehensive input efficiency model, is put forward, and the specific evaluation procedures are given, which can achieve the same ranking function as the balance index model. Furthermore, a comparative analysis of three models is carried out through numerical analysis, and the conclusion is that the balance index model and the comprehensive input efficiency model are more efficient and reasonable.
