Modeling a shared hierarchical structure in data envelopment analysis: An application to bank branches

作者：

Highlights：

• A DEA framework for units in ordered hierarchies with shared functions is studied.

• The proposed DEA framework controls comparability through a flexible constraint.

• A procedure for obtaining economically feasible efficient targets is developed.

• A case study of a branch network with three different branch categories is provided.
