The paper analyzes the existing defects of the theory and application of evolutionary algorithm, neural network and fuzzy logic, the present fusing technologies of intelligent theory and automatic design method of neural network, researches the mutually contained intelligent action and properties of these intelligent theories. Then it proposes the fuzzy evolutionary neural network theory. In the theory, its definition, goal, content and framework system are given, the key serial technologies and their basic ideas and algorithm for fuzzy evolutionary algorithm (FEA),fuzzy evolutionary neural network (FENN) and evolutionary fuzzy system (EFS) from model initialization, self adaptation to automatic design and model evaluation are described. Firstly the approaches of initial selection and self adaptation of control parameters and evaluation means for FEA are put forward. Then the approaches of automatic design, fuzzy initialization and self adaptive evolution of FENN parameters and evaluation of network model are researched for FENN. Finally the parameters optimization approaches of the fuzzy system and fuzzy neural network based on FEA are researched in EFS.
