This paper considers a fuzzy DEA-based model of technical and cost efficiencies with a ranking function. 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… (More)
