The Malmquist Index the prominent Index for measuring the productivity change of Decision Making Units (DMUs) in multiple time periods that use Data Envelopment Analysis (DEA) models with Variable Return to Scale (VRS) and Constant Return to Scale (CRS) technology. In this paper, we compute the Malmquist Index based on Common weights evaluation and by using this method we can rank DMUs by logical criteria. The proposed method is illustrated with a numerical example.
