Study of an explanation mechanism in expert system based on fault tree for Safety Risk Assessment
2010 2nd International Conference on Future Computer and Communication, 2010Co-Authors: Wenhua Song, Huifang Shi, Qinggong LiAbstract:Explanation mechanism provides an understanding window about the reasoning process of expert system for customers. It is an important component of expert system and the explanation function is one of the important features of expert system. In the expert system of Safety Risk Assessment, we used synthesis database to record the solving process and result. Among the synthesis database, the overall data district record overall information and the partial data district record partial information. The solving process is recorded by a reasoning queue based on reasoning-fault tree and explanation information is record in a form structure of relation database. We adopted the method of pre-text combined with path-following to realize the explanation mechanism.

Study on Safety Risk Assessment Expert System in Petrochemical Industry Based on Fault Tree
2009 Second International Symposium on Knowledge Acquisition and Modeling, 2009Co-Authors: Wenhua Song, Huifang ShiAbstract:In this paper, we design a Safety Risk Assessment expert system (SRAES) in petrochemical industry based on fault tree (FT). The expert knowledge is acquired through fault tree analysis (FTA) and stored in a knowledge base (KB) of the expert system. We adopt a rule and framework based reasoning (RFBR) method which is intuitive and conforms to the human thinking customary. This system will figure out two main difficulties, that is, hard to acquire system knowledge and how to construct a high efficient reasoning mechanism. It can realize the Safety Risk Assessment (SRA) of dangerous and harmful factors of the engineering in the petrochemical industry in theory, and improve efficiency and accuracy of the SRA.

Application of Fault Tree Knowledge in Reasoning of Safety Risk Assessment Expert System in Petrochemical Industry
2009 Pacific-Asia Conference on Knowledge Engineering and Software Engineering, 2009Co-Authors: Wenhua Song, Huifang ShiAbstract:In studying the Safety Risk Assessment expert system in petrochemical industry, the conception of fault tree based on binary decision diagrams(BDD) is proposed for fault tree analysis. Taking the boiler fouling explosion for example, the fault tree model and BDD model are built. On the basis of the fault tree model and BDD model, the stress is put on the knowledge representation(KR) of BDD based fault tree in the Safety Risk Assessment expert system and the fault tree knowledge based mechanism of reasoning in this paper.

Study on Urban Public Safety Risk Assessment Based on Protected Objects
2010 International Conference on Internet Technology and Applications, 2010Co-Authors: Bingxue Song, Tong WangAbstract:In this paper, the framework of public Safety Risk Assessment based on protected objects was set up. The process of Risk identification has been developed, which involves determining the protected objects and the scope of Risk identification, analyzing system impact factors and Risk scenarios. In the proposed methodology, the vulnerability was codetermined by both degree of Risk tolerance and Risk control, and a scale of vulnerability was established. On the basis of likelihood and severity of the inherent Risks and vulnerability, a three-dimensional Risk matrix was developed. In existing methodologies, the events are taken as the object of urban public Safety Risk Assessment. Differently, the proposed methodology provides a new idea that the protected object (impact target) is taken as evaluation object, which will make a foundation to enrich the system of more practical public Safety Risk Assessment and methods.

Product Safety, Risk Assessment, and responsible care in the biocide chemical industry.
Regulatory Toxicology and Pharmacology, 1996Co-Authors: E.d. Weiler, Michael A. Jayjock, H.c. LevyAbstract:Manufacturers of biocides recognize a need to control the Risk from their products. This paper discusses some of the history and critical aspects of these activities and outlines the needs under the current initiatives of Responsible Care. Biocide product Safety Risk Assessment is operationally defined in this context and presented as the fundamental tool of the process. The need for data and the criteria for its dissemination are discussed along with the requirement that the data-gathering effort be combined in joint efforts with scientists in industry, academia, and the regulatory community.

Hydrogen Safety Risk Assessment methodology applied to a fluidized bed membrane reactor for autothermal reforming of natural gas
International Journal of Hydrogen Energy, 2015Co-Authors: N. Psara, M. Van Sint Annaland, Fausto GallucciAbstract:Abstract The scope of this paper is the development and implementation of a Safety Risk Assessment methodology to highlight hazards potentially prevailing during autothermal reforming of natural gas for hydrogen production in a membrane reactor, as well as to reveal potential accidents related to hydrogen under certain conditions. The newly developed methodology is able to cover all possible Risk scenarios. The methodology was applied to a novel autothermal membrane fluidized bed reactor integrated within a micro-CHP system of 5 kWel with a PEM fuel cell. The system modelled is based on a prototype developed within the European ReforCELL project. A thorough Safety Risk Assessment methodology was applied examining and evaluating the final outcomes of hydrogen release accident scenarios. The main conclusion of this analysis is that hydrogen may lead to a series of accident types that may pose a threat to the public Safety, however, all considered scenarios fall well within the standard criteria, which indicates the adequate Safety of this novel technology.
