【摘要】：突发事件频繁发生带来的危害使得应急管理在世界范围内越来越被重视,许多国家纷纷投入大量的物力人力开展应急研究工作。其中,应急演练作为检验应急准备工作的重要手段,对于具有不同行动管理机制且缺乏沟通合作的应急组织而言,是提升其应急响应协同处置能力的主要方式。应急演练方案是实施应急演练的依据,负责串联各应急演练成员间的协作,其制定依赖于演练成员间共同的知识基础。然而,应急演练所需知识来源于非结构化文档且存在多源异构的情况,难以在应急演练成员间实现共享,不利于演练过程中信息的传递。为此,本文将本体知识工程引入到演练相关知识的表达中,对基于本体的应急仿真演练方案生成过程进行研究。首先,本文分析归纳了演练相关要素并对其进行本体建模。通过查阅各种演练相关的方案脚本,对多源化的演练相关要素进行提取、分类与定义。同时根据本体建模的原则与方法,在protégé软件中构建演练要素的本体类及相关属性并生成OWL文件。以此为基础,提出了应急演练方案生成方法。在分析方案的内容与结构的基础上,引入数据版本作为演练要素与演练方案中间数据桥梁,从而构成方案生成方法的三层逻辑结构。最后,设计并开发了应急仿真演练方案系统,实现了演练知识与本体文件之间的映射,解决了计算机理解并共享方案数据的问题,并为应急演练仿真服务平台提供了基础数据支持。本文设计的应急仿真演练方案生成方法涉及了知识建模、应急仿真演练、情景构建等多方面的研究,是演练方案知识构建方法的新尝试。其中,提出的演练要素的分析归纳与演练方案的系统化生成是本文研究的难点与重点,通过本体形式数据与文本之间的映射,实现整个仿真平台上的数据共享与互操作,在应急仿真演练的信息化建设中具有应用价值。
[Abstract]:Emergency management has been paid more and more attention in the world because of the harm caused by the frequent occurrence of emergencies. Many countries have invested a lot of material resources to carry out emergency research work. As an important means to test emergency preparedness, emergency drill is the main way to improve the ability of collaborative response for emergency organizations with different operational management mechanisms and lack of communication and cooperation. The emergency drill scheme is the basis for the implementation of the emergency drill. It is responsible for the cooperation among the members of the emergency drill in series, and its formulation depends on the common knowledge base among the members of the drill. However, the knowledge needed for emergency drills comes from unstructured documents and there are many heterogeneous sources, so it is difficult to share information among members of emergency drills, which is not conducive to the transfer of information in the exercise process. In this paper, ontology knowledge engineering is introduced into the expression of relevant knowledge, and the process of generating emergency simulation scheme based on ontology is studied. First of all, this paper analyzes and summarizes the relevant elements of the exercise and carries out ontology modeling. By consulting the relevant scheme scripts of various kinds of drills, this paper extracts, classifies and defines the relevant elements of multi-source drills. At the same time, according to the principles and methods of ontology modeling, the ontology classes and related attributes of walkthrough elements are constructed in prot 茅 g 茅 software and the OWL files are generated. Based on this, the method of generating emergency drill scheme is put forward. Based on the analysis of the content and structure of the scheme, the data version is introduced as the data bridge between the elements of the drill and the middle of the scheme, thus constituting the three-layer logical structure of the scheme generation method. Finally, the emergency simulation scheme system is designed and developed. The mapping between knowledge and ontology files is realized, and the problem of computer understanding and sharing scheme data is solved. And provides the basic data support for the emergency drill simulation service platform. The method of emergency simulation scheme generation in this paper involves many aspects, such as knowledge modeling, emergency simulation exercise, scenario construction and so on. It is a new attempt of knowledge construction method of drill scheme. Among them, the analysis and induction of the exercise elements and the systematic generation of the drill scheme are the difficulties and emphases of the research in this paper. Through the mapping between the ontology form data and the text, the data sharing and interoperability on the whole simulation platform can be realized. It has the application value in the information construction of the emergency simulation drill.
