Developing a two-stage approach of super efficiency slack-based measure in the presence of non-discretionary factors and mixed integer-valued data envelopment analysis

作者：

Highlights：

• Non-discretionary factors and mixed integer-valued DEA are integrated together.

• A two-stage approach of non-radial super efficiency is proposed.

• The projection of an efficient decision making unit is strongly-Pareto efficient.

• The applicability of the approach is examined using an empirical application.
