阀门产品设计知识表示与知识库设计

The Knowledge Representation and Knowledge Base Design of Valve Product Design

为实现阀门产品的快速设计,构建与产品设计相关的知识库,为阀门产品的计算机辅助设计提供知识支持。本文根据阀门产品设计知识的特点,提出了分模块存储的知识组织策略,并给出了相应的知识表示方法,重点探讨了阀门产品实例的面向对象与框架相结合的知识表示。结合相应的知识表示方法,以关系型数据库为支撑平台进行了知识库设计,将相关知识映射为对应的数据表,并通过关系建立了各知识实体间的联系。

To realize the rapid design of valve product,a knowledge base is constructed to provide knowledge support for the computer aided design of valve product. According to the characteristics of knowledge, rite organization strategy of modularization storage and method of knowledge representation is given. The combination of object-oriented and frame representation of knowledge is mainly introduced. A knowledge database is designed on the relational database supporting platform, in which the knowledge is mapped to the data tables and the relations between knowledge entities are constructed.
