| 摘 要： | 本文在分析了单线铁路技术改造方案决策领域知识结构的基础上,提出了一种组合式的知识表示方法,并进一步对优化知识库技术进行了探讨.此外,还在D/S证据理论的基础上,通过建立一种基于区间表示的不确定推理方法,较好地把存在于该领域中的不确定性进行了综合处理.该系统的知识库和不确定性推理方法已在IBM-PC微机上用Turbo Prolog(2.0)开发完成.

| Abstract: | In this paper, the structure of knowledge on concrete reforming schemes of single track railway is analysed. Based on this, the methods of combinative knowledge representation available for the characteristics of the knowledge in this domain are proposed, and many techniques to implement and improve knowledge base are suggested. Furthermore, with the aid of testimony theory of Dempster/Shafer,an interval-valued-based uncertain reasoning model is suggested, but all uncertain information which may exist in single track railway reform is considered. Recently, the knowledge base and the uncertainty inference methods of ESORR-1 have been implemented with Turbo Prolog(2.0), which can be used in compatible computers with IBM-PC. |
