Aiming at the needs of manufacturing enterprise for representation of production design,a production problem query of manufacturing knowledge graph method for knowledge reuse was presented.An ontology based manufacturing knowledge graph was constructed using unified knowledge filter and meta knowledge model.Combining structured ontology query language and temporal query pattern,a knowledge driven and problem driven navigation strategy was proposed,and a semantic matching method was developed.Experimental results show that as a practical case for improving manufacturing enterprise production,the proposed method can not only has high accuracy performance in problem query,but provide effective solutions consisting of knowledge terms and instance descriptions,while it can obtain a general increase in the average accuracy of evaluating indicators by about 15％compared to the existing methods.A feasible solution for knowledge reuse is provided to answer production ques-tions.
