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

世界越来越关注生产和制造工厂的安全要求和安全系统，这些工厂的成本和连续发生事故的风险相对较高。随着安全设计和安全系统技术的进步，大量的安全知识对工厂的运行具有重要的指导意义，降低了运行风险，保证了安全，本文提出了基于本体技术的安全知识建模框架，系统地构建了包括工厂结构、操作和相关行为的知识模型。在这样的工厂知识模型中，安全相关信息被定义并链接到工厂知识模型的不同元素。本体编辑器用于定义基本概念及其相互关系，用于获取和构建工厂安全知识，为了提供详细的安全知识库，HAZOP结果被分析和结构化，以便在工厂知识库中识别和结构化安全相关知识。目标安全知识库包括：基于本体论的安全框架被应用于核电厂的案例研究中，将核电厂的故障、原因、后果和故障传播映射为核电厂知识，并利用所开发的核电厂本体论和知识库支持HAZOP系统进行有效的核电厂安全评估，同时也支持核电厂操作员。后果和故障传播，用于支持工厂操作。

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.
