Two new approaches for linguistic fuzzy modeling and introduction to their stability analysis

Proposes two approaches for linguistic modeling that are suitable for stability analysis of linguistic models. The first approach is called the infinite place model, which is described by modified fuzzy Petri nets and uses a new place definition based on physical infinity. This method has some practical problems. In order to overcome the practical problems, the paper proposes a variation model. Finally it proposes a stability definition and some prerequisite definitions for linguistic stability analysis.
