The Theory of Complex-valued Data Envelopment Analysis (DEA)

Traditional Data Envelopment Analysis(DEA) assumes real-valued inputs or outputs. There has been several studies in the literature dealing with uncertain data set. But the question raises in present of complex-valued data set. The major application of the data set comes back to electronic engineering. So, this paper investigates the DEA models' potential in presence of a real case of complex data.
