基于综合优先级的改进执行时间分配算法

Research on a modified execution time allocation algorithm based on integrated priority calculation

针对相控阵雷达资源的有效管理分配及多任务情况下相控阵雷达的任务执行时间偏移率较高、任务丢失及资源使用率较低等问题,提出基于综合优先级的改进执行时间分配算法。该算法考虑任务的多特征参数,利用优先级表的思想对任务的综合优先级进行计算,并在传统的执行时间顺序分配算法基础上提出改进的自适应执行时间分配算法对雷达驻留任务进行资源调度。仿真实验证明了本调度算法的有效性。

In view of the effective resource management and allocation oi the phasect array ractar as well as the problems of high execution time deviation ratio and task loss and low resource utilization in a multi-task situation, a modified execution time allocation algorithm based on the integrated pri- ority calculation is presented. Considering the multi-feature parameters of tasks, the algorithm utili- zes the idea of priority table to calculate the integrated priorities of tasks. The modified adaptive exe- cution time allocation algorithm based on the conventional execution time sequence allocation algo- rithm is proposed to schedule the resources for radar resident tasks. The algorithm is verified to be valid through the simulation.
