【摘要】 列车运行调整是一涉及范围广泛的复杂问题。根据我国铁路的运营特点,作者从实用化出发,提出了用于编制双线自动闭塞区段列车运行调整计划的专家系统的构造方法。从知识处理的角度出发,对知识表示、知识库构造,规则设计以及人机交互等关键问题的解决方法进行了具体研究,并开发了相应的模拟实验系统。由于不断增加知识就能增强系统的性能,因此系统具有灵活的可扩充性,最终期望能达到有经验调度员编制运行调整计划的水平。更多还原

【Abstract】 Train diagram adjustment is a complicated problem that drags many aspects into consideration. In this paper, according to the operational specifics of China’s railway system, the method is advanced, from the pragmatical angle, of constructing the expert system for working out adjusted train diagrams in automatic block districts of doubletrack lines. Starting from the point of view of knowledge processing,we give detailed studies to such important problems as the expression of knowledge, the construction of the knowledge database, the design of rules and the interface between man and machine, and then set up a simulation experimental system. Since the performance of the system can be simply strengthened by increasing the knowledge, the system possesses a flexible expansibility and can be expected to reach the level of a skilled operator in working out train diagrams.更多还原
