説明
This paper considers a DEA-based model of technical and cost efficiencies with fuzziness. Previous studies of fuzzy DEA model in terms of cost efficiency had critical shortcoming if the unit prices of the inputs are not identical across DMUs in the economy. Therefore, in this paper, a new fuzzy model is proposed by extending the revised scheme of DEA -based cost efficiency that is free from such inconsistencies. The proposed model is a fuzzy programming problem, and so introducing order relations of fur y inequalities, it is equivalently transformed into a linear programming problem. Furthermore, comparing the proposed model with the original model, a numerical example derived from hospital data is provided.
