Abstract: By studying the characteristics of overlapping and hierarchy of complex network community structure and analyzing the characteristics of order products'structure,complex network technique was introduced into modular design of order products and an expression method of product components relationship network was formed.According to this method,the network clusters (community structure) of complex product family network in essence could be regarded as modules of product.An improved Largest Fitness Measure (LFM) algorithm based on the degree of the nodes was put forward and was applied in modular design of order product.In this algorithm,reasonable product modules could be partitioned rapidly while overlapping and hierarchical community structures of complex product family were also revealed simultaneously.Using the Q function as the modular evaluation function,the result of modules compartmentalization was evaluated effectively.The modular design of a wheel loader platform was utilized as an example to demonstrate the effectiveness and feasibility of the method.

Key words: order product, complex network, community structure, modular design, largest fitness measure algorithm
