摘　　要：汽车车身内部布置是汽车设计过程中一项相当重要的工作。本文根据车身内部布置的特点,将基于事例推理的方法引入内部布置过程。采用面向对象的方法表示车身内部布置事例,利用关系型数据库MS Access来建立事例库,应用最近邻法匹配检索车身内部布置的最相似事例,并在参数替换的基础上提出了一个事例修改策略来修改相似事例。以UG 4.0软件作为图形支撑环境,利用VC++作为开发工具,设计了汽车内部布置系统的基本框架,并通过试验系统的开发验证了其可行性和实用性。Auto-body inner packaging is an important job of automobile design. Based on the characteristic of auto- body inner packaging,the case-based reasoning（CBR） methodology is used in auto-body inner packaging processing. Cases are represented with the object-orient method ,and the case base is built with MS Access. The similar cases of auto-body inner packaging are retrieved with the nearest neighborhood method, meanwhile, the similar cases are modified with the modification method on the foundation of parameter replacement. Using UG4. 0 as the CAD support environment and VC ＋ ＋ as programming tool, the framework of the CBR system for auto-body inner packaging is designed, and a prototype system has been developed to verify the feasibility and effectiveness.
