Development of technological information infrastructure based on systematized safety information/knowledge

世界各国越来越重视生产和制造工厂的安全要求和安全制度，这些工厂的成本和持续发生事故的风险相对较高。安全设计和安全系统技术的进步显示了大量有用的安全相关知识，这些知识对工厂运行具有重要意义，降低运行风险，确保安全，提出了基于本体技术的安全知识建模框架，系统构建了包括工厂结构、运行及其关联行为在内的工厂知识模型。在这种工厂知识模型中，定义了与安全相关的信息，并将其链接到工厂知识模型的不同元素。使用本体编辑器定义用于获取和构建设备安全知识的基本概念及其相互关系，并对HAZOP结果进行分析和结构化，从而在设备知识库中识别和构建与安全相关的知识，从而提供详细的安全知识库。目标安全知识库包括：故障、偏差、原因、后果和故障传播与工厂知识的映射；开发了用户界面系统，利用所开发的工厂本体和知识库支持HAZOP系统进行有效的设备安全评估，并用于支持工厂操作员；所提出的基于本体的安全框架应用于案例研究核电站，构造故障、原因、后果和故障传播，用于支持工厂运行。

World is increasing the focus on safety requirements and safety systems for production and manufacturing plants where cost and risk of the continuously occurring accidents are relatively high. The advancement of safety design and safety systems technologies showed large amount of useful safety-related knowledge that can be of great importance to plant operation to reduce operation risks and ensure safety.This research proposes safety knowledge modeling framework on the basis of ontology technologies to systematically construct plant knowledge model, which includes plant structure, operation, and the associated behaviors. In such plant knowledge model safety related information is defined and linked to the different elements of plant knowledge model. Ontology editor is employed to define the basic concepts and their inter-relations, which are used to capture and construct plant safety knowledge.In order to provide detailed safety knowledgebase, HAZOP results are analyzed and structured so that safety-related knowledge are identified and structured within the plant knowledgebase. The target safety knowledgebase includes : failures, deviations, causes, consequences, and fault propagation as mapped to plant knowledge.User interface system is developed to utilize the developed plant ontology and knowledgebase to support HAZOP systems for efficient plant safety assessment, which also used to support plant operator.The proposed ontology-based safety framework is applied on case study nuclear plant to structure failures, causes, consequences, and fault propagation, which are used to support plant operation.
