For the weakness of some fixed weight evaluating methods that it is difficult to identify index weight and ignoring
the individual differences of the observed objects, a non-parametric comprehensive analysis method for evaluating the total
performance of decision-making unit is given by using some sample units, and its corresponding mathematical models are
proposed. Then the meanings, properties and solving methods of these models are given. At the same time, some applications
of this method in measuring the efficiency of decision-making units, ranking the DMUs by the efficiency and analyzing the
reason of inefficiency of DMUs are discussed. Finally, the economic benefits of industrial enterprises in the western China
is analyzed by using the above method.
