针对缺少评估海底信息网系统性能的可靠性指标以及计算方法的现状,从任务可靠性角度分析其功能使命,建立了网络可靠性分析模型,提出了基于传感设备失效时间的可靠性指标(包括系统可靠度和节点抗毁度等),并基于随机故障序列理论和蒙特卡罗思想设计了相应计算方法。仿真分析表明:在模型参数给定情况下,存在满足一定任务需求的维修周期上限。

For lack of the reliability index and measures for assessing the system performance of sea-floor observatory network at present ,this paper establishes a reliability network model on the basis of the analysis of the function of the network from the view point of its tasks and proposes the reliability indexes based on the failure time of sensors ,including node and system reliability .A corresponding calculation method is designed to estimate these indexes according to the theory of stochastic failure sequences and Monte Carlo method .The result shows that given the model parameters ,there is an upper limit of repair period allowed to meet the requirements of a certain task .
