马尔可夫链在预警机任务电子系统信息传输精确度评估中的应用

摘要

Airborne warning and control system(AWACS) mission electronic system is a typical large complex information system,its information transmission precision is a key specification which greatly affects the combat efficiency(such as command and guide) of early warning aircrafts.Characteristics of mission electronic system information transmission process is analyzed,Markov model of information transmission error is established.Application method of Markov chain in information transmission precision evaluation of mission electronic system is proposed,evaluation method and procedures are given;and application example verified that this method is feasible and accurate.%预警机任务电子系统是典型的大型复杂信息系统,其信息传输的精确度极大影响预警机完成指挥引导等作战任务的效能发挥,是预警机效能评估的重要指标。本文在分析了预警机任务电子系统信息传输过程的特点后,建立了信息传输误差的马尔可夫模型,提出了应用马尔可夫链方法对预警机任务电子系统信息传输的精确度进行评估,并给出了评估方法和步骤,最后通过实例证明了这种方法的可行性和准确性。
