导弹预警卫星调度问题分析

Analysis of the Early Warning Satellite Scheduling Problem

以美国天基红外系统的结构和功能为基准,阐述了导弹预警卫星的工作原理和作战流程。采用六元组对导弹预警卫星调度问题进行了详细分析和数学描述。这六元组分别是传感器资源集、可疑目标集、系统状态集、调度约束集、目标可用信息集、调度优化目标集。针对该问题具有实时性和不确定性的特点,提出了一种基于事件和周期相结合的调度方法,给出了一个传感器分配的泛化模型。

According to the structure and function of SBIRS, the working principle and operational flow of the early-warning satellite are expounded. The problem of scheduling the early-warning satellite is analyzed and described mathematically with a six-tuple. This muhi-tuple is a set which includes sensorresources set, suspicious targets set, system-state set, scheduling constraints set, available target-information set, and optimization objectives set. To solve method based on events ＆ periods is put forward and the real-time and uncertainty problem, a scheduling a generalization model for sensor allocation is established.
