The application of a CBR MAS hierarchical model in fault diagnosis system

Due to complexity and diversity of large rotating machinery and working conditions, timely and accurate fault diagnosis can not be guaranteed. The method and process of distributed intelligent fault diagnosis based on MAS(Multi-Agent System) are analyzed, and a hierarchical model which uses case based reasoning (CBR) method to carry out fault diagnosis in fault diagnosis expert system is proposed. Using the model, the system can quickly and accurately analyzes the cause of machinery fault, and provide reasonable and constructive decision-making advice.
