| 摘 要： | 针对现有知识表示方法在智能设计中的局限,提出了一种基于可拓模型的知识表示方法.给出了该方法的定义、语法规范和存储结构.详细论述了基于可拓知识表示的菱形求解策略.包括可拓约束图的构建、物元拓展推理、关联函数计算和条件可拓集合的生成;开发了基于可拓知识表示及菱形求解策略的知识库系统.将该系统应用于水轮机选型设计,得到了比基于规则知识库系统更合理的结果,初步证明了可拓知识表示在解决智能设计知识表示问题时的可行性.

| Abstract: | Aiming at the limitations of the existing knowledge representations in intelligent design,a novel Extension-based Knowledge Representation(EKR) was proposed.The definitions,grammar rules,and storage structure of EKR were presented.A Rhombus Solving Strategy(RSS) based on EKR was discussed in detail,including creation of the extension constraint graph,extended inference of matter-element,calculation of relevant functions,and generation of extension set.A knowledge base system based on EKR and RSS was develop... |
