基于语义网络的推进剂配方设计知识表示

Knowledge Representation of Propellant Formula Design Based on Semantic Network

针对构建推进剂配方设计专家系统时,配方设计知识内容繁多、关系复杂所导致的知识表示困难这一问题,采用语义网络知识表示方法,构建推进剂组方知识语义网络体系,研究该体系在数据库中的存储结构设计,成功地将内容丰富、关系复杂的推进剂配方设计知识表示为适用于专家系统的知识内容。利用专家系统设计的一则改性双基推进剂配方实例展示了该知识体系在推进剂配方设计专家系统中的运用效果。

Semantic network knowledge representation method was used to set up a semantic network system for propellant formula knowledge and to study the structure of this system stored in the database. The knowledge of propellant formulation design with rich contents and complex relationship was expressed successfully as the knowledge content applying to expert system. A modified double-based propellant formula example designed by the expert system shows the effect of using the knowledge system in the pro- pellant formula design expert system.
