摘　　要：分层异构网络应用中存在大量优先级不同的应急数据,它要求苛刻的硬实时和负载均衡性能,超过延时上限,将难以满足应急信息调度需求。常规应急信息资源调度的研究多是以单一任务最早执行完成时间为目标处理资源调度问题,缺乏可调度性,导致调度过程负载不均衡、总任务调度延迟。提出应急信息资源调度模型。确定应急信息资源全部任务相关关系和调度顺序,指定多任务资源分配优先级,建立目标模型,实现应急信息资源调度,适应度函数,指导种群收敛条件,加快调度模型求解效率,将调度负载均衡与总任务调度完成时间问题进行了集成解决。实验结果表明,该模型能够满足应急数据调度要求苛刻的硬实时和负载均衡性能。An emergency information resource scheduling model is presented. The correlativity of total tasks of e- mergency information resources and scheduling sequence are determined. Then, the priority of multitask resource al- location is designated to establish the target model and realize emergency information resource scheduling. Moreover, the convergence condition of population is guided and the solving efficiency of scheduling model is accelerated. The scheduling load balancing and the total completion time of task scheduling problems are solved integratively. Simula- tion results prove that the proposed model can satisfy the requirement of emergency data scheduling, the severe hard real -time and load balancing performance.
