Abstract: Aiming at the evolution control problem of modular product family, a network evaluation approach oriented to complex degree of modular product family was proposed. By abstracting modules as nodes, relations as edges, the module relation network was formed. Based on this network, the product family was described from three layers of module, relation and system, and a five-indicator evaluation system was formed which included module information quantity, module information coupling ratio, module important degree, information strength for relation, and system information structure entropy. Based on engineering meaning of these quantitative indicators, designers could realize the assessment for product complexity and monitoring its evolution state. The feasibility of this approach was verified by using a shovel module system of wheel loader as an example.
