基于分层结构的C4ISR服务部署分布式演化方法

Distributed evolution method of C4ISR service deployment based on hierarchical structure

针对指挥信息系统(command,control,communications,computers,intelligence,surveillance and reconnaissance,C4ISR)服务部署分散、作战平台计算/存储资源有限、演化实时性要求高的特点,基于分层结构设计了系统状态分布式监控与演化总体架构,并在该架构下提出了一种服务部署方案层级动态调整方法。通过定义信息流转长度与方案调整代价设计了服务部署调整方案的数学优化模型,针对部署方案中同时包含服务部署位置和信息流转路径的特点,将成对交换思想、最短路径规划与m-best策略相结合提出了一种贪心求解算法,以实现调整方案的快速生成。实验证明,该方法能够在保证系统信息流转效能的同时有效控制系统的演化范围,适用于执行任务过程中服务部署方案的敏捷调整。

To the characteristics of decentralized deployment of the command,control,communications,computers,intelligence,surveillance and reconnaissance(C4ISR)services,limited computing/storage resources for combat platforms,and high requirements for evolutionary real-time performance,the overall architecture of distributed monitoring and evolution of system state is designed based on hierarchical structure,and a dynamic adjustment method of service deployment scheme hierarchy is proposed.By analyzing the implementation difficulties of the resource coordination module in the overall architecture,the distributed deployment model of the C4ISR service is demonstrated based on defining the evolution cost and information flow path length.To the characteristics that the service deployment location and information flow path are included in the evolution scheme,a pair of exchange ideas,shortest path planning method and m-best strategy are combined to propose a greedy solution algorithm to realize the rapid generation of evolution scheme.The experimental results show that the method can effectively control the evolution range while ensuring the efficiency of system information flow,and can be suitable for the agile adjustment of service deployment method in the process of task execution.
