【摘要】：应急演练是训练处置流程、提高组织协调能力、检验与评估应急预案的重要手段。分布式应急仿真演练将分布式仿真技术与动态桌面演练相结合,既发挥动态桌面演练灵活性高,适应性强的特点,又可利用计算机仿真系统收集详尽的演练过程数据,实现大规模复杂应急环境的仿真并降低实战演练费用。本文从分布式应急仿真演练服务平台需求出发,分析了平台的业务流程,设计了平台的层次式软件体系结构,该软件体系结构将基础服务与业务模块解耦,充分增强了平台的可扩展性与可维护性。在此基础上,本文分析了平台对时间管理与消息管理的需求,并设计了平台时间管理与消息管理的总体框架。针对时间推进与同步问题,本文采取受演练规则约束的时间乐观推进机制,既充分保证仿真的并行性,又保证仿真中各事件的因果正确性。提出了利用同步点算法应对演练过程中异常问题的时间同步方案。针对消息交互问题,本文归纳了平台中消息的交互形式以及具体分类,采取了一套由消息结构化、消息序列化、消息推送、消息持久化组成的消息交互流程,充分提高了消息交互的效率。针对消息的处理问题,设计了消息的调度框架,该调度框架将调度过程与模型运行过程分离,可应对不同的情景和模型。针对消息展示问题,设计了消息的展示方案,使得消息可被合理展示。在此基础上,本文设计并实现了演练导调系统,以此对整个平台的信息条消息、演练进程与节点状态、演练时间等进行管理。为应对演练中可能出现的异常问题提出了适用于本平台的演练恢复方案。通过测试发现,平台在时间管理以及消息管理方面都满足要求。
[Abstract]:The emergency drill is an important means to train the disposal process, improve the ability of organization and coordination, and test and evaluate the emergency plan. The distributed emergency simulation exercise combines the distributed simulation technology with the dynamic desktop exercise. It not only brings into play the characteristics of high flexibility and strong adaptability of the dynamic desktop exercise, but also makes use of the computer simulation system to collect detailed data of the exercise process. The simulation of large scale complex emergency environment is realized and the cost of actual combat exercise is reduced. Based on the requirement of distributed emergency simulation service platform, this paper analyzes the business process of the platform, designs the hierarchical software architecture of the platform, and decouples the basic service from the business module. The extensibility and maintainability of the platform are fully enhanced. On this basis, this paper analyzes the platform's demand for time management and message management, and designs the overall framework of platform time management and message management. Aiming at the problem of time advance and synchronization, this paper adopts the time optimistic advance mechanism, which is constrained by the exercise rules, which not only guarantees the parallelism of simulation, but also ensures the causality of each event in simulation. A time synchronization scheme based on synchronization point algorithm is proposed to deal with the abnormal problems in the exercise process. Aiming at the problem of message interaction, this paper summarizes the interaction form and classification of messages in the platform, and adopts a set of message interaction flow composed of message structure, message serialization, message push and message persistence. The efficiency of message interaction is improved. To deal with the problem of message processing, a message scheduling framework is designed, which separates the scheduling process from the running process of the model and can deal with different scenarios and models. To solve the problem of message presentation, a message display scheme is designed to make the message display reasonably. On this basis, this paper designs and implements the drill guide and tuning system, which manages the information bar message, the status of the walkthrough process and node, the drill time and so on. In order to deal with the possible abnormal problems in the drill, a recovery scheme for this platform is proposed. The test results show that the platform meets the requirements in both time management and message management.
