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。
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 gen- eration of extension set. A knowledge base system based on EKR and RSS was developed, which was applied in tur- bine type selection in intelligent design. More reasonable results were obtained than traditional rule based system. EKR was feasible in intelligent design to solve the limitations of traditional knowledge representations.
