The conception of fault diagnosis method on dedicated observation is presented, and a fault diagnosis method of optimum combination on dedicated observation(OCDO) is given. The method simplifies the requirements for rule and knowledge and improves the utilization ratio of rule and knowledge. Two exmples are given to verify the method, and relevant theorem is also given. Then, a fault diagnosis approach of combination model is established by using neural fuzzy system theory, thus enhancing the learning function and adapability of the method. Finally, simulation results show that the proposed method is effective, practical and worthy of in depth investigations.\;
