Correlative coefficient computing method of configuration module

Applying directed network to represent product family structure,and combining with object-oriented technology,an extended product main structure including generic module and its instantiation module was constructed.An algorithm of correlative coefficients,between any two nodes of filiation or fraternal relationship of extended product main structure,was presented.A transfer method for correlative coefficient was put forward.Calculation result of correlation was applied to product configuration so as to provide a gist for configuration module selection.Finally,all algorithms were applied to turbine stream product family of an industry turbine stream corporation,and the algorithms were verified.
