Abstract

If an external evaluation of decision making units (DMUs) is available based on some bachground information of them, we can estimate it using some defined trade-offs in DEA models. In this paper, we firstly select optimal combination of trade-offs to maximize correlation between external and internal evaluation of DMUs and then we set up the targeted trade-off production possibility set by using the selected optimal trade-offs. Considering this PPS as a based technology in the Malmquist index, we can extend the malmquist productivity index. In the following, a new factor as “external evaluation factor” is introduced so we can present new decompositions of Malmquist index. Finally, using a numerical example we illustrate the extended Malmquist index and its decompositions
