摘　　要：在分布式仿真中,同一实体的多个分辨率模型并发以及不同实体的各个分辨率模型之间的交互会导致数据表现不一致的问题。在分析现有多分辨率建模方法的基础上,提出了适应分布式仿真环境的不同分辨率模型的树状结构建模方法,其主要由聚合级实体模型和平台级实体模型组成。为解决树状结构建模方法中不同分辨率模型的数据表现不一致问题,将不同分辨率模型间的交互看成分布式数据库中的事务,由此提出了一个嵌套两段式提交协议算法来有效解决不同分辨率模型的一致性维护问题。In distributed interactive simulation,the interactions among the multi-resolution models of the same entity and the multi-resolution models of different entities may cause the problem of data inconsistency.Based on the analysis of existing multi-resolution modeling methods,a tree configuration modeling method was proposed for multi-resolution modeling in distributed interactive simulation,which is composed of aggregated entity models and platform entity mo-dels.In order to solve the problem of data inconsistency in the multi-resolution models of the tree configuration mode-ling method,the interactive among the multi-resolution models was regarded as the transaction of distributed database management.Then a nested 2-phase-commitment protocol algorithm was proposed to settle the consistency maintenance of multi-resolution models.
