摘要
时延网络是一种针对网络系统节点故障导致时间延迟的网络,由于研究该型网络要以网络系统任务完成时间是否及时为研究目标,使其任务可靠性研究与以往的网络有所不同.通过两次运用BDD算法,给出了时延网络任务可靠性的计算方法,并对算法中的优先序作了研究.以快速研制系统任务网络为例,说明了时延网络任务可靠性的算法的应用方法.BDD算法使用方便,易于计算机实现.
Time-delayed net is a kind of net in which faults of joints in the net make the time delay of mission. Mission in time-delayed net success means that the mission finished in time, so the method in studying the mission reliability in the time-delayed net is different from the post nets. The mission reliability for the time-delayed net is given by using two times BDD （binary decision diagram） algorithm. The build order of BDD diagram is given, which is better than the past process. An example of quick researching and manufacturing system is given to illustrate the method, which demonstrates that the method is good.
