摘　　要：根据汽车车身内部布置的特点,通过扩展对象模型提出了车身内部布置事例的面向对象表达模型,将车身内部布置的约束分为范围、规则和表达式3种形式,并研究了其对象表达模型。利用最近邻方法检索相似事例,结合参数替换和约束满足方法提出了布置事例修改策略,实现了布置事例的修改。利用UG和VC++开发了试验系统,应用实例验证了方法的可行性和有效性。Considering the characteristic of auto-body interior layout,the object-oriented case presentation models of auto-body interior layout were presented by employing the extended object model,in which the index and solution objects were appended.Constraints of auto-body interior layout were divided into three forms： domain,rule and formulation,and their definitions were described with object models.The nearest neighborhood method was adopted for case retrieval.The strategies for case adaptation,combining parameter substitution with constrain satisfaction,were presented to modify case solution.A test system was developed with UG and VC＋＋,and the application shows the validity and feasibility of the presented method.
