Development of CBR system for embedded purpose

As the complexity of the launching vehicle increases, using fault diagnosis method to improve reliability becomes more and more important. CBR (case-based reasoning) method is frequently used in prognostic and health management systems. The launching vehicle system has many subsystems. In order to apply CBR method to these various subsystems, a CBR system based on Java and MySQL database is designed in this paper. The principle and process of modular structure is discussed, and case base database based on MySQL is designed. The system is developed in the Java language according to three layer model. It can be used for embedded application. Two data sets from UCI database are used to test module function. Test result shows validation of the system.
