A Novel Collaboration-Oriented Requirement Model Mapping and Classification Method Based on Domain Knowledge for Complex Mechatronic Products

Abstract

Complex mechatronic products include inter-disciplinary, inter-field, and inter-departmental requirement information. Aiming at the low digitization rate of existing product requirement information, a structured and digital product requirement model (RM) is defined. Besides, a collaboration-oriented requirement model mapping and classification method for complex mechatronic products is proposed, which realizes the automatic generation of the domain requirement models and the mapping between the requirement models and knowledge graph, thus improving the digitization rate of the product in the requirement phase. A simulated military plane horizontal tail control system is used as a case study to prove the effectiveness and feasibility of this method. Based on Hoteam PLM8.0 platform, a management architecture and the display path of product requirement model are given, which can provide a reference for the research and development of product lifecycle model management (PLMM) system.
