Fig. 8. GC c and commonality parameters by varying parts' occurrences.

Color image of this figure appears in the color plate section at the end of the topic.

The increase of w c part has a large effect on w part . In fact, it decreases, and
consequently, w att increases as are shown in Fig. 9. Form this graph, we
observe that GC v decreases with the decrease of w part , as well, and varies
from 0.79 to 0.60. We observe, as the commonality of parts increases the
