摘要
在建造专家系统中虽然有很多种知识表示方法,但都有不尽人意的地方。本文试图用一种新的方法——Petri网模型来表示知识。本文给出了Fuzzy Petri网和广义Fuzzy Petri网两种模型,并给出了相应的推理算法。一旦专家知识用Petri网表示后,根据Petri网固有的特性,我们就能处理专家系统中并行推理、无回溯推理、反向推理等问题。
With models of Fuzzy Petri nets and general Fuzzy Petri nets, this paper presents a new method for fuzzy production rules of a rule-based system which allows clear representation and easy analysis of concurrency and asynchronous reasoning. Algorithms for reasoning are also proposed, and the description of the model and fuzzy reasoning algorithms are described in detail.
