本文针对工程类知识的多样化特点及实时性、规模、易维护性和综合问题求解等系统实用化指标，研究并实现了一种基于关系型构造的新型工程知识推理平台ＲＥＫＰ。文中论述的工程知识的关系模型及相应的知识群机制，使系统既便于知识维护和实现海量存储，又使问题求解达到高效率。性能测试与综合比较表明ＰＥＫＰ在实时性、存储、知识管理和易维护性等方面具有综合优势。
In this paper, according to the diversification characteristics of engineering knowledge and practical indexes such as real-time, scale, easy maintenance and comprehensive problem solving, a new kind of engineering knowledge reasoning platform REKP based on relational structure is researched and implemented. The model of engineering knowledge and the corresponding knowledge group mechanism discussed in this paper make the system not only maintain knowledge and mass storage, but also make the problem solving highly efficient. Performance tests and comprehensive comparison show that PEKP has comprehensive advantages in real-time, storage, knowledge management and easy maintenance.
