【摘要】 探讨了在天然气管道运行中调度员和专家系统的基本任务,所介绍的专家系统用于优化天然气管道系统的运行,可以降低运行成本。针对管道运行过程中存在的一些不确定和不精确信息,在专家系统中引入模糊集和模糊逻辑的理论,以描述此类信息,可在人类和机器之间提供一种更加自然的联系方式,并着重讨论了知识的获取及模糊控制规则。此外,文章所述方法提供了一种比较方便的天然气管道优化控制方式。更多还原

【Abstract】 The basic tasks of dispatcher and expert system arc discussed in the operation of gas pipelines. The introduced export system is used for optimized operation of gas pipelines to reduce the running cost. Aiming at some uncertain and imprecise information, the theories of fuzzy sets and fuzzy logic arc introduced in the expert system to describe the information and offer a more natural communication mode between human and machine. The knowledge acquisition and fuzzy control rule are discussed emphatically. The method offered in the article provides an easily optimized control mode of gas pipelines.更多还原
