Based on BDI modal, the main function of diagnostic agent is implemented in three aspects: as CBR(Case Based Reasoning), production diagnostic system and artificial neural network, These three methods mentioned above are processed step by step.

• 以BDI结构模型为基础，从CBR(基于实例的推理)、产生式诊断系统和神经网络诊断系统三个方面实现了诊断Agent的诊断功能。
