摘　　要：为了解决海洋环境下武器装备效能的评估问题,利用成熟的关系数据库技术提出了一种通用的知识表示方法,构建出海洋环境对武器效能影响评估系统的知识库。首先介绍了知识的两类来源,分析了效能评估知识的特点,表明传统的知识表示方法难以满足该评估系统的计算要求。然后详细地阐述了将规则、函数、算法、模型等统一到一个关系数据库中的通用关系知识表示方法,与一般知识表示进行比较,并根据其特点研究通用关系知识库的知识存储结构以及效能评估系统的推理机。最后给出基于框架知识的知识表示和推理实例。一个完善的通用关系知识库的构建将有助于解决海洋环境下武器装备效能的定量评估问题,为决策提供参考。Aiming at the problem of efficiency evaluation for weapon equipment under marine environment and using the mature technolo- gy of relational database, a universal knowledge representation method is proposed, and the knowledge base for the evaluation system is designed. First, two kinds of the sources of knowledge are introduced, and the characteristics of the efficiency evaluation knowledge are analyzed which shows that traditional knowledge representations are hard to satisfy the computing requirements of this efficiency evalua- tion system. Secondly, the universal relational knowledge representation, which unifies the rules, functions, algorithms, models, etc. into one relational database, is expounded in detail by being compared with normal knowledge representation. According to the characteristics of universal relational knowledge representation, the storage structure of universal relational knowledge base and inference engine of the e- valuation system are studied. Finally, an example based on frame knowledge and inference engine is given. A perfect universal relational knowledge base can help to solve the problem of quantitative efficiency evaluation for weapon equipment in marine environment and pro- vide references for decision-making.
