分布式集群协同仿真研究

分布式集群协同仿真是指地域上分布、系统上异构的多个节点群为实现某一复杂的仿真目的而进行互连并进行内容级的互操作的一种复杂、大型、综合的协同仿真。其中每一个节点为一个仿真系统(或仿真器)或控制系统或服务器，多个节点互连形成为节点群构成具有明确仿真目标的综合仿真系统，井且这些节点群综合仿真系统种类多样(虚拟仿真系统、实物仿真系统、构造仿真系统等)、具有层次结构(如军事上战略仿真、战役仿真、战术仿真、装备仿真等)、地理上，“域分布(WAN或INTERNT环境)而且它们之间的连接关系较为复杂(一对一、一对多、多对一、多对多等)。该文提出了“分布式集群协同仿真”与“双时仿真”的概念与构想；研究并设计了分布式集群协同仍真的体系结构；建立了多节点分布集群协同仿真时间管理策略；构建了几类典型协间仿真系统运行控制的算法。分布式集群协同仿真由于具有分布、异构、广域、多粒、层差等特性，因此，分布式集群协同仿真研究既足一个实践课题，同时也是一个理论课题。该文的研究，主要集中在分布集群协同仿真层次的多节点复杂大系统的应刚领域，属实践课题研究。

Distributed Aggregated Collaborative Simulation

Distributed aggregated collaborative simulation is a large-scale,complex,integrated cooperation simulation,in which many different simulation systems have been interconnected and interacted at content level in distributed geographic regions for a common simulation purpose.Thereinto each simulation system may be a system,or simulation control system,or simulation server which has a hiberarchy as military strategy simulation,compaign simulation,tactical simulation,equipment siulation and different types such as virtual simulation,live simulation and constructive simulation.The connectting relations amony these simulation systems are also very complex,including one to one,one to many,many to one and many to many relations. Based on this reason,this paper puts forward the concepts of both distributed aggregated collaborative simulation and double-clocks distributed interaction simulation, designs the structure of distributed aggregated collaborative simulation and provides a time management scheme of the multi-nodal distributed aggregated collaborative simulation,builds a few of typical executive control models of collaborative simulation system.
