分布式武器目标分配中的实时截止期分配

在分布式武器对目标的协同拦截中,作战任务往往被划分为多个子任务,为了保证任务的实时性,针对分布式武器对目标的协同拦截问题建立实时任务模型,运用分布式实时系统中的截止期分配技术,把全局作战任务的截止期转化为其包含的各子任务的截止期.建立了任务调度模型和仿真模型,对分配有截止期的子任务实施仿真调度,研究了在一定武器数量情况下,不同来袭目标数量和武器节点上本地负载所占不同比例时,各截止期分配方法保障任务实时性和完成率的能力,可为实时条件下的分布式任务协作研究提供参考.

Deadline assignment in real-time cooperative interception of distributed weapons

In the cooperative interception of distributed weapons, a task is often divided into several subtasks. To ensure the tasks fulfilled in real-time, the overall deadline of a global task was translated into deadlines for subtasks using deadline assignment technique in distributed real-time systems. By building the task scheduling model and simulation model, subtasks with deadlines were scheduled in a simulate way at the precondition that weapon amount is constant while the target amount and the proportion of local load on weapon nodes are changing. According to the results, the performance of different methods on task instantaneity and complete rate was analyzed, which can provide reference for research on cooperation of distributed real-time tasks.
