Measuring Efficiency Using Fuzzy DEA and Fuzzy Constraints to Control Weights and to Find a Common Set of Weights
In this paper it has been tried to present a model by usingsome changes in the classical DEA Ball - Bat - Baseball USA Approved models and combining these modelswith fuzzy models to eliminate these weaknesses.Inputs and outputs arerecognized by using MCDM and AHP techniques and experts views.Inthe next step, the gathered data is compounded by fuzzy
