The invention discloses a complex system module division method based on system, function and structure layering, and belongs to the field of modular manufacturing. The method comprises the followingsteps: firstly, establishing an SFS hierarchical model, and establishing a module division principle based on a functional structure and a DFX on the basis of the SFS hierarchical model; then providing a pre-division principle for module pre-division, and reducing the complexity of the system; under the guidance of a module division principle, establishing each sub-correlation matrix, and establishing a comprehensive correlation matrix according to the weight; solving a granularity interval of the module, and generating a module division scheme set in combination with an improved genetic algorithm and an FCM clustering algorithm; and evaluating the module division scheme set to obtain an optimal module division scheme. A complex product system is divided into reasonable modules, preparation is made for subsequent module configuration, assembly, recovery and the like, and the design and production efficiency is improved.
