The Multi-scale Modeling Technique for Modular Variant Design

Facing the modularization of existing product variant design requirements, this paper presents a multi-scale modeling technology. Discuss the process of the change scope of the parts and modules according to the needs of the user, so divide the modular product model into process model, modules model and parts model. Use associated hypergraph describe the constraint relation between different stages of modular design process, the process model provides network basis for user needs mapping. Use the structured hypergraph to conduct formal description of parts and modules information and establish structured model; then fuse constraint information of the structure model based on the multi-scale data fusion technology, and provide constraint data source for changed coefficients of the components and modules. Finally, the case analysis shows the scientific and practical of the method.
