基于人工神经网络的机械设计过程专家系统知识库的设计与实现

机械设计作为一门复杂而具有创造性的学科，其知识具有复杂性，模糊性和不确定性，将特定的知识固定于特定的设计阶段，不仅造成知识库的冗余，同时也是不科学的，采用人工神经网络与专家系统结合的方式，实现了机械设计知识库设计知识的模糊分类，对系统的功能，结构模式，有关知识获取，网络构成及推理过程等关键问题进行了分析设计，并论证了集成系统的优势。

Design of Knowledge Base of Expert System in ANN-Based Mechanical Design Process

Mechanical design, as a complicated and creative subject, the knowledge is of complexity, fuzzy and uncertainty. Confining some knowledge to a specific design stage would cause redundancy of the knowledge base, which is also unscientific. The method of combinating neural network with expert system is used as a processing tool, which realizes the fuzzy classification of design knowledge. The function and structure module of the system, the key technical problems of knowledge acquisition, network structure and reasoning are analyzed, and the dominance of integrated system is demonstrated.
