基于模糊综合评价方法的实例检索策略研究
Case retrieval strategy based on fuzzy comprehensive evaluation method

针对实例推理设计中如何快速按一定的相似度检索出相关实例的问题，提出了一种基于模糊数学综合评价的检索方法，用面向对象的实例表达方法，主要研究如何确定机械设计依据的属性特征的相似度，将模糊数学概念、灰色关联分析理论应用于实例检索过程中，用层次分析法和熵值法确定特征属性的组合权重。以启闭机设计为例，验证了检索算法的高效性、可靠性和实用性
Aiming at the problem of how to quickly retrieve the relevant instance according to a certain degree of similarity in case reasoning design, this paper proposes a retrieval method based on fuzzy ？？comprehensive？？ evaluation.With object oriented case representation methods, we mainly study how to determine the similarity of attribute characteristics in mechanical design basis. The proposed retrieve method introduces fuzzy mathematics and grey relation analysis into the case retrieval process, and the combination weight of feature attributes are determined with the analytic hierarchy process and entropy value method. Taking the hoist design as an example, the efficiency, reliability and practicability of the proposed retrieve method are validated
