Abstract: To deal with actual maintenance requirement of equipments,a fault diagnosis model is proposed based on CBR under mobile computing.Taking full account of the difference between the mobile devices and PC performance,the case retrieval which is the core of the CBR is optimized,and the similarity matching algorithms is discussed in detail.Finally the model is verified by experiments.The experimental results indicate that the model is applicable to mobile devices,and has high efficiency.
