Product configuration method based on ontology mapping

Customer requirement has the characteristics of vagueness, incompleteness and time -varying. An ontology model of product family case and customer fuzzy requirement was constructed by using sharing and reusability of ontology on semantic layer. The fuzziness of customer requirement was expressed by introducing the fuzzy ontology of linguistic variables; The incompleteness of customer requirement was solved by introducing the rules of ontology and constructing ontology rule base; The time -varying of customer requirement was solved by normalizing parameter of customer requirement and product family. It used multi -strategy ontology mapping method to achieve matching between customer requirement ontology and product family case ontology to realize product configuration based on customer requirement. Finally, the computer product configuration is taken as an example to verify the feasibility of this approach.
