摘要
为定量分析防御系统可靠性,提出了传统平台中心化和新型网络中心化的系统可靠性设计方法。首先,分析了2种系统的体系结构。平台中心化系统采用层次化串联结构;网络中心化系统采用栅格化体系结构,将各级系统组成一个以网络为中心的整体。然后,在2种系统结构基础上提出了2种防御系统的可靠性模型。最后,通过仿真实例,计算了2类系统平均故障间隔时间和故障率。仿真计算结果表明,在不增加计算资源前提下,基于共享资源结构的网络中心化防御体系可有效提高系统可靠性。
To analyze defense system reliability quantitatively,a traditional platform centric warfare-based reliability model and a novel network centric warfare（NCW）-based reliability model are proposed.Firstly,the architectures of two systems are analyzed.The hierarchical series structure is adopted by the platform centric system.The rasterized architecture is adopted by the network centric system,making all level systems form a network centric whole.Then,based on two kinds of the system structures,two reliability models for defense systems are proposed.Finally,the mean time between failures（MTBFs）and the failure rate of two kinds of systems are calculated by simulation examples.The simulation result shows that the resource-sharing-based network centric system can achieve good reliability under the condition of even computation recourse.
