Abstract. The conventional analogous maps are gradually substituted by the 4Ds, i.e., DLGs, DRGs, DEMs, and DOMs. In various fields of national economic, 4Ds are applied extensively and people attach much importance to the quality of 4Ds. The paper discusses fuzzy comprehensive evaluation techniques. The implementing process and its characteristics are also analyzed. Taking the comprehensive evaluation of DEMs as an example, a model for fuzzy comprehensive evaluation of DEMs is developed.

Keywords:  DLGs,DRGs, DEMs, DOMs, quality model,  fuzzy evaluation
