A fuzzy systems approach in data envelopment analysis
The use of fuzzy set-theoretic measures is explored in the context of data envelopment analysis, which utilizes a nonparametric approach to measure efficiency. Three types of fuzzy statics are employed here e.g., fuzzy mathematical program, fuzzy regression and fuzzy entropy, to illustrate the types of decisions and solutions that are achievable, when the data are vague and prior information is inexact and imprecise.
