Benjiang Ma, Qiu Wan-hua · Systems Engineering · 2005
This paper gives a new linear equivalent form of C~2R-model for the multiple solutions problems of C~2R-model. In the light of this linear equivalent form, the definition of strong DEA-efficient is introduced and an equivalent theorem of DEA-efficient decision cells is showed, which reflects the economic implications of DEA-efficient decision cells, and it is (emphasized) that strong DEA-efficient is how to improve on the conception of DEA-efficiency. Finally, by the definition of non-inferior vertex of multi-surface convex cone, the geometry meaning of strong DEA-efficient is illustrated, and an (example) is given.
