أسلوب تحليل مغلف البيانات الضبابي (Fdea)‎ بين النظري و التطبيقي

Abstract EN

This study aims to shed light on a very advanced method, which is the fuzzy data envelopment analysis method that integrates fuzzy logic with the traditional data envelopment analysis method, by addressing the theoretical grounding and application thereof.

the most important results are that the models of the data fuzzy envelope analysis method allow to measure the efficiency in a fuzzy environment, which is the closest to the practical reality, in using one of the approaches proposed in this method, the most important of which is the α-level based approach is based on transforming the fuzzy data envelopment analysis model to a pair of parametric programming problems using alpha cuts, which can be solved by relying on the "dear" statistical package in the R program, and despite using fuzzy numbers in estimation; the end results are more accurate and reliable.
