Several models of fuzzy finite-state automata have been proposed in the literature. One model which benefits from the existing algorithms for designing Boolean finite-state machines, has been proposed by J. L. Grantner [8]. This model, which is called Hybrid Fuzzy-Boolean Finite State Machine (HFB-FSM), along with its algorithmic design procedure, can be used for implementing dynamic linguistic systems [7,8,13]. In this thesis we have developed a simulation program for the HFB-FSM model using C++ programming language. In order to simulate a HFB-FSM model, the user provides the information defining the system's behavior. Based on the algorithm proposed in [8], the simulation program constructs the state transition table and overall linguistic model for each fuzzy state. The on-line interaction of the simulator with the user, allows to tune the adjustable parameters of the system in order to obtain satisfactory results. For any set of inputs and initial condition, the simulated HFB FSM model makes the appropriate state transition and generates the corresponding outputs. Simulation results have illustrated the capability and effectiveness of the HFB FSM model in modeling the behavior of the dynamic linguistic systems.
