Two-stage DEA model with additional input in the second stage and part of intermediate products as final output

作者：

Highlights：

• We propose a two-stage DEA model that the intermediate product is freely distributed.

• We get the upper and lower efficiencies of each stage using leader–follower game.

• The non-linear programming model is transformed to a parametric linear programming.

• A heuristic search algorithm is designed to obtain the cooperative efficiency.

• A set of appropriate proportion for intermediate products is obtained.
