Based On Ontology Tabular Layouts Of Article Characteristic's Variant Design Research

Variant design applies similarity,reusability and global principle of custom products to reorganize,improve the use of existing parts,increase the customer choices.According to customer custom needs,it produces low-cost,high quality and efficient production of customized products by mass production.Although the variant design method can meet the customer's personalized custom needs to a certain extent,but in the variant design,the reuse of the principle of application is not enough,and can not achieve the product information reasoning function.In the view of the two problems mentioned above.In the process of variant design,the application of reuse principle is not enough,and can not achieve efficiently.This paper introduces tabular layouts of article characteristics and ontology to analyze the customized products,get tabular layouts of article characteristics,and establish the relationship between the product master model and the characteristics of things.This paper describes the tabular layouts of article characteristics with the description logic,and sets up it's tabular layouts of article characteristics.The main model of the customized product,the size constraint relation hierarchy diagram,the main structure of the product is added in the tabular layouts of article characteristics,and then extended it.Besides,this paper uses ontology to infer the product's related information.The main works are as follows:First of all,this paper constructs the domain ontology knowledge based on the tabular layouts of article characteristics and ontology.It analysis the product components and the relationship between parts and components and use the Web Ontology Language to define it.It analysis the product of constraint relationship,assembly constraints,expert experience and other related knowledge,it represented by the SWRL.It switches the product parts of the knowledge to Jess facts,and switch the main model of the customized product,the size constraint relation hierarchy diagram,the main structure of the product to Jess rules.The Jess reasoning mechanism is used to construct the ontology knowledge base of the variant design field,and the relevant information of the variant design product is reasoned to get the demand information.The correctness of this method is verified by the example of gearbox axle gear,which provides the theoretical basis for realizing the variant design of the product.Second,based on the ontology and things attribute table variant design method.Based on the advantage of the knowledge reuse of the ontology,the main model and the main structure of the customized product are added to the object attribute table to expand it.On the basis of this,the derived parameters,model,the main structure of the reasoning rules are constructed.Finally,the prototype system based of tabular layouts of article characteristics and ontology is developed.On the basic of ontology knowledge base,four layer frameworks are constructed.To develop the custom system based on tabular layouts of article characteristics and ontology by ontology editing tools protégé software and Java programming language.The correctness of the variant design method has been proved by engineering examples.
