分布式仿真系统中的全局一致性问题研究

系统一致是分布仿真应用DSA的基础和前提。为提高DSA的全局一致性程度,获得真实、可信的仿真结果,首先阐述了DSA全局一致性问题;然后以某分布仿真系统为例,系统阐述了其全局不一致现象;在此基础上,分析了DSA系统的全局一致性需求;最后,重点给出了模型域、服务域和认知域内的一致性控制策略与建议。本研究可为DSA系统设计与开发人员提供技术与方法指导。

Global consistency issues in distributed simulation systems

System consistency is the basis and premise of distributed simulation applications (DSAs). In order to improve the global consistency degree and gain realistic and credible simulation results in DSAs, we firstly elaborate the global consistency problems and then describe the global inconsistency phenomena systematically. On this basis, we analyze the global consistency requirements of DSAs, and provide some effective control measures and advice for generalized consistency control in model domain, service domain and perceive domain, which can provide technical and methodological guidance for the design and development of DSAs.
