【摘要】：随着现代各种科技手段的结合，对水上安全的考核越来越多的采用的是系统的观念来分析，因为以往的方式评价单一，不能反映整体运行指标。本文是在评估某航运安全的前提下，分析其发生事件的因素指标，而单一的指标只能部分的反映事物的发展规律，不能全面的给予表达，所以我们要用系统的观点，综合考虑各种因素，而在评价安全性的问题上，必须考虑可靠性和实际需求，这样才能在现有的事件的基础上，对未来做出比较准确的推测。本文是基于贝叶斯网络的某航运安全状况监测系统，可以对某航运安全做出监测。本系统是基于C/S结构，在Visual Studio2008开发环境下，通过Access数据库以及GeNIe(图形网络接口)软件的充分结合，来进行整体系统实现的。系统先使用GeNIe软件建立贝叶斯网络模型（xdsl文件），然后再调用SMILE的应用程序接口将填入的概率代入模型中进行推理计算。相比以前的软件，此软件不必在系统中直接建立贝叶斯网络网络模型，减轻了系统的负载，提高了运算速率和系统的效率。首先，根据需要提出方案。贝叶斯网络具有解决不定性问题方面的优点，再结合GeNIe软件可以很方便的建立贝叶斯网络模型，然后通过软件进行构建和更新，可以得到相应的数据，这是建立软件的数据基础。其次，方案的整体设计。需求分析的制定，软件平台和系统结构的选择以及数据库的抉择，以及总体方案的设定。系统是根据某航运安全状况的实际需要，，结合GeNIe软件建立的贝叶斯模型，然后通过接口与之结合，在Access数据库和VS2008平台下，使软件运行在微软donet3.5（或以上）框架的环境下。最后，系统的实现。根据需求编写相应的代码，然后调试运行，在实现功能的前提下，又建立良好的交互界面，方便用户操作，也方便系统后期的维护和功能更新方面的管理和实现。该系统实现了实际需求，被测系统的操作运行良好，系统的可靠性强，可以通过多种图形显示给用户，符合现代用户的视觉和实际需求，接口的运用，方便后续的改进和需求的增加。
[Abstract]:With the combination of modern scientific and technological means, the assessment of water safety more and more uses the concept of the system to analyze, because the previous way of evaluation is single. Can not reflect the overall operating indicators. This article is in the evaluation of a shipping safety premise, analysis of the occurrence of events of the factors indicators, and a single index can only partially reflect the development of things. Can not be fully expressed, so we should use a systematic point of view, comprehensive consideration of various factors, and in the evaluation of security, we must consider the reliability and actual needs. In this way, based on the existing events, to make a more accurate prediction of the future. This paper is a monitoring system based on Bayesian network, which can monitor the safety of a certain shipping. The system is based on C / S structure. In the Visual Studio2008 development environment, through the Access database and the Geni (graphical Network Interface) software fully combined. The system uses GeNIe software to establish Bayesian network model and XDSL file. Then the application program interface of SMILE is called to substitute the probability in the model for reasoning calculation. Compared with the previous software, the software does not have to directly establish Bayesian network model in the system. The load of the system is reduced, and the speed of operation and the efficiency of the system are improved. First of all, according to the needs of the proposed scheme. Bayesian network has the advantages of solving uncertain problems, and then combined with the GeNIe software can be very convenient to establish Bayesian network model. Then the corresponding data can be obtained by building and updating the software, which is the data base of building the software. Secondly, the overall design of the scheme, the formulation of requirement analysis, the choice of software platform and system structure and the choice of database, as well as the setting of the overall scheme. The system is based on the actual needs of a shipping security situation. Combined with the Bayesian model established by GeNIe software, and then through the interface with the combination, in the Access database and VS2008 platform. Make the software run in Microsoft do 3.5 (or above) framework environment. Finally, the implementation of the system. According to the need to write the corresponding code, and then debug the operation, in the implementation of the premise of the function, but also build a good interactive interface, convenient for users to operate. It also facilitates the management and implementation of later maintenance and function update of the system. The system realizes the actual requirements, the operation of the system is good, the reliability of the system is strong, can be displayed to users through a variety of graphics, in line with the visual and practical needs of modern users, the use of interfaces. Facilitate subsequent improvements and increased demand.
