英文摘要：
To reasonably plan and develop product family, an expansion analysis model of customer requirements based on ontology description was proposed to mine and predict customer requirements. Holographic semantics based on ontology was adopted to describe customer requirements and the relationships between them. According to the current customer requirements and product information, quantitative and qualitative expansion of requirements was carried out in the aspects of requirement features, feature attributes and relationship between requirements. Qualitative expansion provided requirements for horizontal series while quantitative expansion provided those for vertical series. Considering the difference between customer requirements, they were clustered to reasonably plan diversified types and series for product family design.
