一种评估专家系统的研究

STUDY ON AN ASSESSMENT EXPERT SYSTEM

针对飞行器飞行状态的人工评估日趋复杂和困难的问题,将评估树技术和专家系统技术相结合,提出一种用于飞行器任务评估的综合分析模型。首先介绍系统总体结构设计,分析系统各模块的功能和联系;然后,提出一种知识表示模型以及知识获取与转换流程,建立基于数据库的知识库;最后,分析专家系统推理机制,通过不确定性推理提高系统的推理有效性。工程实践表明该专家系统是可靠有效的。

Since the manual assessment for aircraft flying states becomes increasingly complex and difficult, in the paper we propose to combine the assessment tree technology with expert system technology, and present a Comprehensive analysis model for aircraft mission assessment. First, we introduce the design of system＇ s overall structure, analyse the functions and relations of various sub-modules in the system, and then we put forward a knowledge representation model and a knowledge acquisition and conversion flow, set up a database-based knowledge library. Finally, we analy^e the inference mechanism of expert system, and improve the reasoning effectiveness of the system by uncertainty reasoning. Engineering practice shows that the expert system is reliable and effective.
