摘要
针对基于实例推理的产品配置设计中客户需求匹配搜索的问题,引入了实体集、实体、属性、主属性集、相似元等概念,建立了基于实体属性的相似度计算模型;研究了产品配置过程中客户需求与产品结构单元特征之间的映射关系,提出了相似度的计算流程;分析了属性的类型、值域和权重,提出了属性相似度的计算方法和实体相似度的计算公式。给出了一个泵体配置的相似度计算实例。
Aiming at matching searching of customer demand in product configuration design of casebased reasoning, the conception of the entities, the entity, the attribute, the primary attribute set,the similar element etc. were introduced, and the similarity calculation model based on entity attribute was established; the mapping relationship of customer demands and the product structure cellular feature during the process of product configuration was studied, and the calculation flow of similarity was put forward; the type, range and weighting of attribute were analyzed, the calculation method of property similarity and formula of entity similarity were advanced. Finally, the similarity calculation example for the pump body configuration was given.
