A novel fuzzy non-radial data envelopment analysis: An application in transportation

The slack-based measure (SBM) DEA model is a non-radial used to calculate the relative efficiency, input, and output targets of different decision-making units (DMUs) based on their best peers or efficient frontier. conventional SBM crisp inputs outputs. But, it can be observed in real-life problems that sometimes available data linguistic forms such as “few”, “many”, “small”, missing data. technique frontier based, therefore, imprecise may lead untenable results. Fuzzy theory, which already established handle uncertain data, overcome this problem. Furthermore, sensitivity stability analysis have been checked robustness fuzzy models. In study, has performed. lower upper sensitive bounds for outputs variables obtained both inefficient DMUs input targets. Finally, transportation problem validity study presented its depiction.
