摘要: 结合改模方案分层递阶表达模型和信息系统同态的定义分析方案结构化处理,论证了方案结构化处理同为信息系统同态。利用信息系统同态的相关定理和推论,分析特征约简与信息系统同态不变的关系,论述了方案结构化处理和特征约简操作保持了改模方案特征决策表之间的相容关系,进而得出不同方案层次级别下的注塑模改模知识之间具有相容关系(即不会存在矛盾)的结论,从而阐明了改模方案分层递阶表达模型及相关粗糙集发现方法在改模知识发现上的合理性。

Abstract:  As a kind of knowledge, a scheme of injection mould modification is represented hierarchically. Then, such knowledge is structuralized, which is shown to be information system homomorphism. Based on theories of information system homomorphism, the relation between feature reduction and information system homomorphism invariance is analyzed. Results show that feature reduction of the injection mould modification knowledge at different scheme levels is compatible with the feature decision tables. Thus, the structuralization of the injection mould modification knowledge is useful for knowledge representation and induction in mould modification.

Key words: information system homomorphism, injection mould modification knowledge induction, knowledge compatibility
