Abstract: With the application of automobile intelligent design system，it is inevitable that a large number of outdated and redundant knowledge are accumulated in the knowledge base． In this case，the efficiency of the design knowledge reuse is affected seriously． In order to improve the accuracy of design knowledge evaluation，AHP is introduced into assessment system of automobile intelligent design knowledge; the corresponding index system is designed; and the evaluation process is studied． Knowledge base of automobile intelligent design system has been optimized to improve quality and efficiency of intelligent design by effective evaluation of design．

Key words: intelligent design, analytic hierarchy process ( AHP) , knowledge evaluation, automobile design

摘要： 随着汽车智能化设计系统的应用，系统知识库中不可避免的积累大量过时、冗余的知识，其会严重影响到设计 知识的重用效率。为了提高设计知识评价的精确度，将层次分析法引入到汽车智能化设计知识的评价体系中，建立 汽车智能化设计知识的评价指标体系，研究了汽车智能化设计知识的分析评价过程。通过对设计知识的有效评价， 可以实现汽车智能化设计系统知识库的优化，有助于改善智能化设计的质量和效率。
