Traditional DEA-based ranking techniques have some pitfalls such as ignoring the inherent differences among decision making units(DMUs),or lacking a common weight-based ranking,etc.To overcome these obstacles, the paper first examines the possible differences among all DMUs such as the technical efficiency difference,the preference structure difference and the within-group position difference.Based upon the above differences this paper induces an integrated ranking measurement which helps to give a fair and full ranking for all DMUs under evaluation.Following the three types of differences,this approach behaves greatly elaborately,accurately and reasonably.Finally,the results from the Olympics achievement evaluation approve the acceptability of this approach.
