Data Envelopment Analysis with Uncertain Inputs and Outputs

Abstract EN

Data envelopment analysis (DEA), as a useful management and decision tool, has been widely used since it was first invented by Charnes et al.

in 1978.

On the one hand, the DEA models need accurate inputs and outputs data.

On the other hand, in many situations, inputs and outputs are volatile and complex so that they are difficult to measure in an accurate way.

The conflict leads to the researches of uncertain DEA models.

This paper will consider DEA in uncertain environment, thus producing a new model based on uncertain measure.

Due to the complexity of the new uncertain DEA model, an equivalent deterministic model is presented.

Finally, a numerical example is presented to illustrate the effectiveness of the uncertain DEA model.
