Reliability is an important parameter in evaluating the performance of a communication network . anew algorithm of computing networks reliability by using binary decision diagrams ( bdd ) is presented in this paper . the algorithm can get a much simpler bdd diagram than the other algorithms , and can reduce the complexity of the computation efficiently 关于网络可靠度,在已有结果的基础上,提出了一种利用二元判决图计算网络可靠度的方法,该方法将网络的最小路集用二元判决图来表示,并得到最小路集的不交和,最后获得网络的可靠度。
In the first two chapters , the basic knowledge of traffic accident , its causes and the relationship between road sense and traffic accident are mainly analyzed . it introduces the application of present compute network in traffic management ; the deficiency in the training and it introduces the examination and background of developing this system too . policy foundation , academic basis , runnable environment of developing the system , urgency , necessity and feasibility are also presented in these parts 全文共分五章,前二章主要分析了交通事故的基础知识,交通事故发生的原因,机动车驾驶员驾驶技能与交通事故的关系;介绍了我国现行计算机网络在交通管理工作中的应用情况,机动车驾驶员培训考试的不足和开发此系统的背景,提出了开发研究该系统的政策依据、理论基础、运行环境、紧迫性、必要性、可行性。
In order to realize remote diagnosis using cbr expert system , case base is created based on web database by importing internet into expert system . cscw is a sort of distributed computing network . it can complete corporation of multi members who are in different space and different time by the use of modern computer technique , multimedia , network and humor - computer interface 计算机支持的协同工作( computersupportedcooperativework , cscw )是利用现代计算机技术、多媒体技术和网络技术以及人机接口技术,将时间上分离、空间上分布而工作上又相互依赖的多个协作成员及其活动有机的组织起来,以共同完成某一任务的分布式计算环境。
