为了解决基于HLA的分布交互仿真中数据分发管理的现存算法数据过滤率低、仿真时间长而影响仿真结果和应用的问题.在对过去各种数据分发管理算法的深入分析基础上,提出了数据分发管理的变尺度动态网格算法.分析了网格单元尺寸与更新时间、数据过滤率、接收时间及排队时间的关系,并对该算法进行了理论证明和公式推导.通过将采用该算法的数据分发管理仿真系统与采用静态网格法的数据分发管理仿真系统及采用线性规划法三种方法对一简化的化工系统进行产品优化及能力均衡的对比研究,证明该算法有效的提高了数据过滤率、缩短了仿真时间、改善了仿真效果,验证了其有效性和实用性.

Dynamic Grid-based Method Research in Data Distributed Management

In order to resolve the problem that distributed interactive simulation based on HLA takes too much simulatiom time and has a low data filter rate using past data distributed management algorithm.A dynamic grid-based method in data distributed managemen is pointed out in this paper thoroughly analysing the static and dynamic algorithms of data diatributed management.Based on further analyzing the relationship between the update time and data filer,receiving time and queue time,theory proof and formmula deduction of the algorithm are done in this paper.Comparision researched of three methods of static grid-based,dynamic grid-based and linear programming was done in the problem of products optimization and capability equilibra of a simple petrolchemical sytem.The results show that the algorithm improves the rate of data filter and reduces the simulation time consume,and verify the availability of the algorithm.
