Abstract: Applying
directed complex network to model the main structure of product family,
according to in-degree bi-logarithmic coordinate distribution curve and
distribution rule of nodes of the network, in-degree evolving rule of
nodes of the network is presented, analytic expression of in-degree
probability density of nodes is derived. Through the analysis of
relation between existing kinds of component and existing product
number, an expression of the relation between kinds of component and
product number is built. A forecast method of increment of component
number and parts based on the increment of product is presented. As an
example, the component number of industry stream turbine product family
is forecasted, forecast result is verified and forecast error is
analyzed.
