摘要
为解决源程序中公式更新、公式重复编码、知识难以重用以及参数混乱等问题,把工程设计系统中的计算公式从源程序中独立出来,通过公式类知识管理系统来管理公式和参数。分析了公式类知识的组成,研究了知识的增加、删除、修改、浏览、搜索、唯一性检查、一致性检查、结构有效性检查、语法有效性检查以及冲突检查等多项技术,研究了管理系统中公式在智能设计系统的调用技术。以汽车空调压缩机设计系统为例,介绍了公式类知识管理系统的开发和应用。
To solve the problems of formula updating, repeated formula coding, difficulty of knowledge reuse and disordered parameters, the calculation formula was extracted from the source program of engineering design system and an algorithm-type knowledge management system was designed to deal with it. In the algorithm-type knowledge management system, the basic objects were parameter, algorithm expression and formula. The algorithm expression knowledge was described, and its operation technologies in knowledge management system were probed, such as knowledge augmentation, deletion, modification, view, inquiry, as well as grammar effectiveness checking, uniqueness checking, conformity checking, structural effectiveness checking and conflict checking. Formula transformation technology of knowledge management system to intelligent design system was studied. The algorithm-type knowledge management system was developed and applied in designing system of air-conditioning compressor.
