【摘要】：應(yīng)急演練是訓(xùn)練處置流程、提高組織協(xié)調(diào)能力、檢驗(yàn)與評估應(yīng)急預(yù)案的重要手段。分布式應(yīng)急仿真演練將分布式仿真技術(shù)與動態(tài)桌面演練相結(jié)合,既發(fā)揮動態(tài)桌面演練靈活性高,適應(yīng)性強(qiáng)的特點(diǎn),又可利用計(jì)算機(jī)仿真系統(tǒng)收集詳盡的演練過程數(shù)據(jù),實(shí)現(xiàn)大規(guī)模復(fù)雜應(yīng)急環(huán)境的仿真并降低實(shí)戰(zhàn)演練費(fèi)用。本文從分布式應(yīng)急仿真演練服務(wù)平臺需求出發(fā),分析了平臺的業(yè)務(wù)流程,設(shè)計(jì)了平臺的層次式軟件體系結(jié)構(gòu),該軟件體系結(jié)構(gòu)將基礎(chǔ)服務(wù)與業(yè)務(wù)模塊解耦,充分增強(qiáng)了平臺的可擴(kuò)展性與可維護(hù)性。在此基礎(chǔ)上,本文分析了平臺對時間管理與消息管理的需求,并設(shè)計(jì)了平臺時間管理與消息管理的總體框架。針對時間推進(jìn)與同步問題,本文采取受演練規(guī)則約束的時間樂觀推進(jìn)機(jī)制,既充分保證仿真的并行性,又保證仿真中各事件的因果正確性。提出了利用同步點(diǎn)算法應(yīng)對演練過程中異常問題的時間同步方案。針對消息交互問題,本文歸納了平臺中消息的交互形式以及具體分類,采取了一套由消息結(jié)構(gòu)化、消息序列化、消息推送、消息持久化組成的消息交互流程,充分提高了消息交互的效率。針對消息的處理問題,設(shè)計(jì)了消息的調(diào)度框架,該調(diào)度框架將調(diào)度過程與模型運(yùn)行過程分離,可應(yīng)對不同的情景和模型。針對消息展示問題,設(shè)計(jì)了消息的展示方案,使得消息可被合理展示。在此基礎(chǔ)上,本文設(shè)計(jì)并實(shí)現(xiàn)了演練導(dǎo)調(diào)系統(tǒng),以此對整個平臺的信息條消息、演練進(jìn)程與節(jié)點(diǎn)狀態(tài)、演練時間等進(jìn)行管理。為應(yīng)對演練中可能出現(xiàn)的異常問題提出了適用于本平臺的演練恢復(fù)方案。通過測試發(fā)現(xiàn),平臺在時間管理以及消息管理方面都滿足要求。
[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.
