摘要
分析了产品计算机辅助模块化设计中模块选择的过程与选择策略 ,提出了可用模块的概念与判别方法 ,以文中提出的树形模块存储结构为基础 ,给出了模块选择的详细算法 ,其中通过引入模糊数学中相似优先比的有关理论 ,提出了一种对各属性因素进行综合定量考虑的“最相似模块”查找算法。文章最后 ,用检索实例对所提出算法的有效性进行了验证。
This paper analyzed the process and selection strategy of module selection in computer aided modularized design of products,put forward the concept and distinguishing method of usable module.Taking the storage structure of tree shaped module advanced in this paper as a foundation a detailed algorithm of module selection is presented.Through the introduction of the related theory of priority ratio of similarity in fuzzy mathematics,a kind of investigating and seeking algorithm of “most similar module” which carries on a synthesized and quantitative consideration on various attributive factors is advanced.Finally,using a retrieval example to carry out the verification on the effectiveness of the put forward algorithm.
