摘　　要：基于案例的推理在设计、规划、决策、分类、评估等方面发挥重要作用。为进一步提高通过案例解决问题的适用能力和应变能力,挖掘群体案例的潜在价值,提出一种柔性化案例知识处理方法。这一方法采用不变部分+可变部分+可选部分+规则的组合框架来提高案例知识的处理能力,采用结构化数据组织方式来表达案例内部数据及案例与案例之间的层次关系,实现了案例知识的有效组织和完整表达。以某企业民机典型零件机加工工艺为例,验证了柔性化案例知识处理方法的可行性。这一方法为复杂问题的求解提供了理论依据,具有一定的工程应用价值。Case-based reasoning plays an important role in design,planning,decision-making,classification,and evaluation.In order to further improve the application ability and adaptability of solving problems through the case,and to explore the potential value of group cases,an approach for flexible manipulation of case knowledge was proposed.This method adopts a grouped frame of constant part+variable part+optional part+rule to improve the manipulation capacity of case knowledge,and uses structured data organization to express the internal data of the case and the hierarchical relationship between the cases,so that effective organization and complete expression of case knowledge are realized.Taking the machining process of typical part of an enterprise’s civil aircraft as an example,the feasibility of the approach for flexible manipulation of case knowledge was verified.This approach provides a theoretical basis for solving complex problem and has certain engineering application value.
