Abstract:
This paper studies the feature relat ionship based on const raint. First ly it analyses the relat ionship betw een constraints and it s products and influence on the product formation, and points out that ex pression of the feature relat ionship is important research f ield in parameter . Based on researching dif ferent const raint relat ionship among features, a graph called Feature Relat ionship Graph( FRG) is given to ex press these relat ionships and at t ributes. Finally it discusses the detail algorithm to manage the FRG. The result of the paper has applied in the product modeling system ( XLMFCAD) of a CIMS eng ineering .
