. Since the efficiency of a two-stage system in a period is the product of the two process efficiencies, the overall … efficiency of a decision making unit (DMU) in the specified period of time can be decomposed into the process efficiency of each …

In measuring the overall efficiency of a set of decision making units (DMUs) in a time span covering multiple periods … calculated at the same time. Notably, the overall efficiency is a weighted average of the period efficiencies, and the weights … measure the efficiency of 22 Taiwanese commercial banks for the period of 2009–2011. The three-year multi-period analysis …

The conventional data envelopment analysis (DEA) models for measuring the relative efficiency of a set of decision … being the units at the bottom of the hierarchy. Due to the characteristics of a parallel system, the efficiency of a …

Network data envelopment analysis (DEA) concerns using the DEA technique to measure the relative efficiency of a system …
