An object-oriented implementation of a knowledge representation scheme based on Fuzzy Petri nets

An object-oriented implementation of an original model of knowledge representation scheme is described in the paper. The model is based on the high-level Fuzzy Petri nets and supports three forms of reasoning: inheritance, recognition and intersection search. The model is suitable for knowledge base and inference machine design in intelligent systems for real-world tasks that deal with fuzzy, vague, human-like linguistic expressions. The components of the implementation and user-friendly interface that enables effectively using the implemented system are described. An illustrative example of using the object-oriented implementation of the fuzzy knowledge representation scheme that demonstrates some of the main characteristics of the user-friendly graphical interface is given.
