| 摘 要： | 定性映射是从哲学上事物的质-量互变规律出发,以感觉特征抽取为依托而建立的脑思维数学模型。文章以定性映射基本定义为基础讨论了属性Petri网的基本模型,给出了其形式定义和基本运行机制,描述了基于属性Petri网的知识表示模式,最后给出了属性Petri网的相应推理算法。该模型在以定性判断为特点的诊断系统中能得到较好地应用。

| 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.In this paper,based on the basic definition of qualitative mapping,the attribute petri nets model is discussed.Its formal definition and its basic running mechanism are provided. The knowledge representation model based on attribute petri net is described.Finally,this reasoning algorithm of attribute petri net is also provided.It is proved that this model is useful in the diagnosis system characterized with the qualitative judgement. |
