A Forgotten Point in Technology Selection

The assumption of classical technology selection models is based on complete homogeneity of technologies. In spite of this assumption in many applications some technologies do not comprehensively consume common inputs to comprehensively supply common outputs. The objective of this paper is to propose a Data Envelopment Analysis (DEA) model for selecting slightly non-homogeneous technologies. A numerical example demonstrates the application of the proposed method.
