【摘要】 深航做为国内第一批开展航空安全管理系统(SMS,Safety Management System)的试点单位,目前正处于高速发展阶段,急需开发一套从公司实际情况出发,能够评估安全状况、发现安全隐患、引导安全行为的风险评估系统来推进安全管理的系统建设,从而实现最有效的安全管理控制。本文以系统管理的理念对深航的风险评估与预警进行需求分析,从系统安全管理的角度出发,研究如何通过软件实现过程风险评估,即建立人为因素风险评估与预警系统,并对系统实现的关键技术进行阐述。本文开发的人为因素风险评估与预警系统在技术应用范畴属于管理信息系统,整个系统的开发符合软件工程的设计流程和理念,而系统的开发模式使用的是面向服务的体系结构SOA(service-oriented Architecture)。针对公司已有部分系统需要整合的需求,新的系统平台必须具备开放性、高效性、灵活性等特点,选用ASP.NET开发技术平台,ORACLE数据库进行总体设计。根据安全管理实际需求,系统共分为偏差子系统、QAR子系统、安全培训管理、网上准备监控、系统管理、信息交流与服务等模块,目前主要功能都已经实现,可在公司范围内利用QAR数据、内部评估信息、外部评估信息、偏差事件、员工报告等多维度输入安全信息,通过一段时间的累积形成基础安全信息数据库,与此同时,安全信息还将得到正确的分类分析处理,转化为各类危险源的基础数据资料,只要设立风险值的可接受程度,系统将自动对当前的安全状况做出评估预警,实现安全信息的全面综合应用,也是建立完善安全管理体系的一大助力。更多还原

【Abstract】 As the first batch of domestic pilot units to carry out Aviation Safety Management System(SMS), Shenzhen Airlines is currently in a stage of rapid development, so it is in urgent need of risk assessment system that is able to assess the security situation, identify the security risks, and guide safe behavior in accordance with the actual situation of the company, so as to promote the development of SMS and thereby achieve the most effective security management and control. With the theory of system management, the paper conducts demand analysis on risk assessment and early warning of Shenzhen Airlines. Proceeding from system security management, the author also discusses how to launch risk assessment through software, namely how to establish human factor risk assessment and early warning system, and elaborates key technologies for system implementation.The human factor risk assessment and early warning system developed by the author belongs to management information system in the scope of technological application. The system is in line with the design process and idea of the software engineering, and its development mode utilizes the service-oriented architecture(SOA). In order to integrate the existing system of the company, new one shall be open, efficient and flexible, so the author employs ASP.NET development technology platform and ORACLE database in respect of the overall design.Based on the actual needs of the safety management, the system is divided into deviation subsystem, the QAR subsystem, safety training and management, online preparation and monitoring, system management, as well as information exchange and service, etc. Currently, major functions have been achieved and the system is able to utilize multi channels such as QAR data, internal assessment information, external assessment information, deviation incident and staff report to input security information which will form basic security information database after accumulation. At the same time, with correct classification and analytical processing, the safety information is able to provide the basic data for various sources of danger. By setting acceptability of value-at-risk, the system will automatically assess and give early warning on the current security situation. Comprehensively utilizing safety information also plays an important role in establishing a sound SMS.更多还原
