基于 HLA的装备分布式虚拟维修训练过程极易产生仿真节点负载失衡，以往的负载平衡研究多关注资源利用率，仿真运行过程中可能会因节点负载的不均衡进行频繁的负载调度，影响仿真运行效率。针对此问题，以保证仿真节点的高效运行为首要目的，将负载平衡定义为不存在超载节点即为平衡，提出了一种动静结合的复合式负载平衡调度方法。研究了复合式负载平衡系统的体系结构，采用最小连接调度法实现了节点静态负载的粗粒度平衡，引入仿真运行比率分量参数表征负载量值，进而设计了动态负载平衡算法对仿真运行过程进行实时监控和调度。实验结果表明，改进后仿真平衡调度频率明显下降，实现了资源利用率和仿真效率的平衡兼顾，取得了良好的效果。

The load of simulation nodes based on HLA goes easily out of balance in distributed vir-tual maintenance training system.The previous research used to focus on efficient use of re-sources,which cause frequently dynamic adjustment of load balancing and affect the simulation ef-ficiency.In order to solve this problem,a method combining static load balancing and dynamic load balancing is proposed.According to the weapons distributed virtual maintenance training simula-tion characteristics,a parameter named simulation runtime ratio is introduced;a rough load balan-cing is realized based on minimum-link-dispatch method;a dynamic load balancing algorithm is designed.The results show that after the improvement is made simulation efficiency increases significantly.
