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。
Aiming at the problem that the formula design knowledge has a great deal of contents and the complex knowledge leads to the difficult expression of knowledge when constructing expert system of propellant formula design, this paper uses semantic network knowledge representation method to construct the knowledge semantic network system of propellant group, In the design of the storage structure, the successful presentation of the knowledge of the rich and complex propellant formulation design as the knowledge content suitable for expert systems. An example of modified double base propellant formulation designed by expert system shows the application effect of this knowledge system in propellant formulation design expert system.
