A two-stage DEA model considering shared inputs and free intermediate measures

作者：

Highlights：

• Allocation of inputs and intermediate measures in efficiency evaluation is modeled.

• Overall efficiencies evaluated by conventional and proposed model are decomposed.

• Traditional model over-evaluates the efficiency of process with complex structure.

• Conventional two-stage model sub-evaluates the efficiency of the same process.

• Proposed model revise efficiency score by considering intermediate measures structure.
