| 摘 要： | 针对网络系统状态空间的巨大问题,提出用最大概值状态生成法生成网络实际运行时最可能出现的状态,并定义数字0和1的一种运算,以生成网络的断集空间用于判断网络状态的正常与故障。从而在网络部件寿命以及修理时间均为指数分布时,可应用马尔可夫过程理论获得网络系统的稳态可用度,首次故障前平均时间,稳态故障频度等指标,并举例进行说明。

| Abstract: | To counter the state space problem of a network system, The most probable states are generated by using GENERATE algorithm, and a method to classify the network states is designed through defining an operation between 0 and 1 to obtain the seg space of network, then Markov process theory is introduced to obtain some important reliability index supposing life and repair time are exponentially distributed. Finally the process is demonstrated by an example. |
