        The classification of fuzzy uncertain data is considered one of the most challenging issues in data analysis. In spite of the significance of fuzzy data in mathematical programming, the development of the analytical methods of fuzzy data is slow. Therefore, the current study proposes a new fuzzy data classification method based on fuzzy data envelopment analysis (DEA) which can handle streaming data.The new method is tested by simulated data and the results indicate its effectiveness in facing uncertain data and variable conditions.

        2 - A Hybrid Method of DEA and MODM in Grey Environment
        Alireza Alinezhad
        DEA Classic models cannot be used for inaccurate and indeterminate data, and it is supposed that the data for all inputs and outputs are accurate and determinate. However, in real life situations uncertainty is more common. This article attempts to get the common weight More
        DEA Classic models cannot be used for inaccurate and indeterminate data, and it is supposed that the data for all inputs and outputs are accurate and determinate. However, in real life situations uncertainty is more common. This article attempts to get the common weights for Decision-Making Units by developing DEA multi-objective models in the grey environment. First, we compute the privilege of DMUs efficiency to receive more accurate ranking. Finally, in order to assess the results, an example is presented to compare the results of the DMUs ranking between DEA Classic models and the presented model. Manuscript profile
