The next step is to derive the local relative weights of the three measures. The four evaluators respectively provide the ordered pairs for the three measures. Tables I-IV, represent the judgments of the four evaluators respectively:

The four weight vectors of the three measures respectively by the four evaluators are obtained according to the calculation algorithm:

With the relative weights of the evaluators’ opinions, the judgments of the performances’ local weights are incorporated:

After the performance grade matrix and the local relative weights of the three performances of this process have been obtained, the measurement result of this process can be aggregated as follows: P = P 6X3. A =

These four vectors compose the 3 * 4 weight matrix:

On one hand, this result, which denotes the measurement of this process, can be further aggregated with the measurement results of the other parallel processes as the algorithm above does. On the other hand, this result can be
