Performance Measurement ‎T‎echniques In the Presence of Undesirable Products

Abstract

Performance measurement with undesirable outputs is an important subject in production processes. There are papers in which works can be divided into two groups. First group develops production models which undesirable outputs are considered as inputs and in second one undesirable outputs are modeled as outputs. We provide a comparison between these two groups and we axiomatically show that production technology with weak disposability assumption is complete and correct technology.
