Intelligent Construction Method of Complex Equipment MBOM Based on Process Knowledge Template
Aiming at the problems of insufficient reuse,cumbersome process and low efficiency in the construction of MBOM in complex equipment assembly process,an intelligent construction method of MBOM based on process knowledge template is proposed.The improved"EBOM-MBOM"process design pattern is defined and the knowledge-driven intelligent process of MBOM construction is designed.The data mode of standard process design concept entities and the relation between entities are defined.Knowledge is extracted from historical assembly process design case documents based on rules.Standard process knowledge maps are constructed,and standard process template libraries are formed.Based on the graph similarity,the assembly process template is matched,and the classic WL graph core algorithm is improved to improve the matching accuracy.Finally,the feasibility and effectiveness of the method are verified by the process design of typical UAV components.
