摘要: 从哲学上事物的质-量互变规律出发,定性映射是以感觉特征抽取为依托而建立的脑思维数学模型。该文提出了基于定性映射模型的诊断系统的建模工具(属性Petri网的基本模型),给出了形式化定义和基本运行机制,分析了基于属性Petri网的诊断推理算法及实例,该模型在以定性判断为特点的诊断系统中,能得到较好的应用。

Abstract: Qualitative mapping based on the conversion of quantity-quality features of attributes in philosophy and perceptive feature extracting is a mathematic model of thinking. This paper discusses a model of diagnosis system based on the qualitative mapping: the attribute petri nets model. It provides its formally definition, basic running mechanism, reasoning algorithm of diagnosis and instance based on attribute petri net. It is proved that this model is useful in the diagnosis system characterized with the qualitative judge.

Key words: Qualitative mapping, Attribute Petri net, Diagnosis, Modeling
