Abstract: To evaluate the commonality of modules in modular product platform scientifically,structure network of product family was constructed and a network methodology to modules commonality analysis was proposed by applying network theory.Parts or modules were regarded as nodes and subjection relations as edges,two networks of product family were constructed including parts network and modules network.Important parameters for module's commonality such as out-degree,in-degree,betweenness,utilization times and product number of each module were analyzed.Computing method and physical meaning of five network parameters were introduced.Generic Parts Commonality Index (GPCI) based on network model was designed by analyzing the correlativity among five parameters.As a practice example,the commonality of the industry steam turbine modules was discussed.Compared with the application of parts and modules in the company,the result showed that the network method and GPCI could be applied to module's commonality analysis quantitatively and reasonably.
