摘　　要：对高层体系结构(HLA)中数据分发管理(DDM)的研究,主要目标是在符合HLA标准的前提下,提高数据的过滤效率,同时减少计算量,并提供较好的可扩展性适应于各种规模的分布式仿真应用。Lookahead是分布式模拟时间管理协议中的一个重要概念,各模拟实体使用Lookahead把自己产生事件的时间标记情况更早地通知给其它实体,以加快程序的运行。采用颜色Petri网和Lookahead的数据分发机制,能够很好地对数据进行过滤,提高数据的过滤效率,并能保证数据收发的成功率。仿真实验结果表明:基于颜色Petri网和Lookahead的数据分发机制是优于区域匹配方法的。To the research on the High Level Architecture（HLA） in the Data Distribution Management（DDM）,the essential target is to enhance the data filter efficiency,to reduce computing quantity at the same time,and to provide well scalability for some kind of distribution simulation application under the HLA standard.Lookahead is an important time management concept in distributed simulation,in order to speed up the procedure,each simulation entity informs fimestamp produced using Lookahead to other entities as far as possible early.Using the data distribution mechanism based on the colored Petri net and Lookahead,the data filters can be well carried out,the data filter efficiency can be enhanced,and the success rate of the data dispatching and receiving can be guaranteed.The simulation experiment result indicats that,the data distribution mechanism based on the color Petri net and Lookahead is better than the region match method.
