网络中电子测量信息资源有效调度仿真研究

Research on Effective Scheduling of Electronic Measurement Information Resources in Network

对网络中电子测量信息资源的调度,能够有效提升网络信息资源的利用率。对电子测量信息资源的调度,需要得到信息调度属性值的分布差异,计算其相对权重,完成测量信息资源的有效调度。传统方法得到各个信息的信任属性,给出每个测量信息的信任效益函数,但忽略了计算其相对权重,导致信息资源调度效果不理想。提出基于多属性信息的网络中电子测量信息有效调度方法。对大规模测量信息调度属性间的从属关系进行计算,得到测量信息调度属性值的分布差异,计算测量信息调度属性的相对权重,融合DPA调度优先级抢占方法计算信息任务的即时价值,获取当前剩余价值密度与开始时刻剩余价值密度的比率,计算出完成信息任务所需的执行时间与任务空余时间的比,以此为依据完成对网络中电子测量信息有效调度。实验结果表明,所提方法调度精度高,有效地提升电子测量信息资源的利用率。

An efficient scheduling method of electronic measurement information in network is proposed based on multi - attribute information. The slave relation among scheduling attributes of large - scale measurement information is calculated, and distributional difference of scheduling attribute of measurement information is obtained. Then rela- tive weights of scheduling attribute of measurement information are calculated, and DPA preemptive dispatcher priority method is integrated to calculate immediate latent value of information task. Moreover, the current density ratio of re- sidual value and density of residual value at the beginning is obtained, and the execution time ratio for completing in- formation task and spare time of task is calculated. On this basis, the effective scheduling of electronic measurement information in network is completed. Simulation result shows that the proposed method has high accuracy and can ef- fectively improve the utilization of electronic measurement information resources.
