Research on component relation network of product family and its application

Applying complex network theory to mass customisation. A component relation network is constructed. Statistical parameters of the network are calculated and bi-logrithmic coordinate distribution curves of the parameters are drawn. A universality analysis method of component is proposed. In-degree evolving rule of the network is proposed. The analytical probability density function of in-degree distribution is derived. A modularisation comparing method of the product family is presented. A use number forecast method of component is presented. The methods are applied to a steam turbine product family, and the methods are verified.
