Abstract: This article introduces the structure of condition-based maintenance expert system, and a structure and algorithm about modular neural network is proposed. By means of decomposition decision sub-modular, it can automatically divide a complex task into a series of sub tasks which are processed by their corresponding subtask nets. The combination strategy can arrive at a solution to a given task. The research shows that the structure and algorithm is practicable and effective. It has higher parallelism and is easy for training new samples.
