| Objective: Data envelopment analysis is a well-known method based on mathematical programming to measure the efficiency of decision-making units. This approach identifies some units as efficient units set. According to these units, it constitutes an efficient frontier. In this case, discernment between efficient decision-making units are is impossible because several decision-makers have the same efficiency score. Methods: This study presents a new method for ranking efficient units in fuzzy data envelopment analysis. In this study, using a fuzzy inference system for ranking efficient units is proposed as a new method. In the proposed method, the efficient and inefficient units are first separated from each other using data envelopment analysis. Then, the concepts of fuzzy inference system are used to rank efficient units. Results: The information of inefficient units is in a way which the fuzzy data envelopment analysis fails to assign an equivalent value of one to these unit’s efficiency. According to this concept, in the proposed method, each of these inefficient units is considered as a rule, and the amount of these rules are fired by the efficient units, has used as an indicator for their ranking. Conclusion: Finally, a numerical example is performed to check the accuracy of the model's performance. In this example, the data used in one of the basic articles in this field were used and it was found that the results obtained from the proposed method are quite similar to the results of the mentioned research. | ||
