作者：

Highlights：

• A DEA method for identifying FDH-efficient DMUs.

• Two DEA models for the estimation of right and left RTS of FDH-efficient DMUs.

• A DEA method for determining MPSS in FDH models.

• Presentation of two examples to illustrate the use of our proposed approach.

• Making comparisons among our RTS method and other RTS methods in FDH models.
