Methods and models for the risk analysis and security management of chemical plants

Fuzzy-Situational Diagnostics of Technological Safety of Petrochemical Plants

“…In addition, there are difficulties in solving the problems related to diagnostics and management of technical safety in complicated technical systems that occur in various emergency situations. These difficulties arise due to the fact that the most of decisions are made facing the conditions of uncertainty and fuzziness of the initial information, and there are practically no possibilities of using the existing deterministic stochastic models [1][2][3][4].…”

“…An analysis of the principles of constructing diagnostic systems and managing technological safety with petrochemical plants and complexes leads to the conclusion that a significant feature of this class of systems is the presence of a large number of input and output parameters that characterize the state of the system in an ambiguous manner, the absence or incompleteness of knowledge about the physicochemical process parameters [2][3][4][5]. Additional difficulties in solving the problems of diagnosing and managing technological safety with complex technical systems in various emergency situations arise due to the fact that decisions are mainly made in the conditions of uncertainty and fuzziness of the initial information and there are practically no possibilities to use the existing deterministic-stochastic models [3][4][5][6][7][8].…”

“…CURRENT RESEARCH Based on the above, it can be said that for the effective management of complicated technical processes described above there is an urgent need for the development of new methods, models, and approaches. These scientific approaches can assist in the assessment of the status of technical equipment and related processes, the algorithms and methods and for ensuring the safe functioning of facilities in various industrial and technical situations, and these models need to be based on the use of modern information technologies as well as intelligent decision support tools [4][5][6][7][8][9].…”

“…In this case, the programming software needs to be developed in accordance with the emergence of new tasks. This could be an intensive way of industry development, which differs from the extensive one, where the solution to the problem was sought by constantly attracting new resources; the extensive way does not help to reduce the costs of maintaining the regimes [3][4][5][6][7][8][9][10][11][12].…”

Identifying University Chemicals That Pose Security Risks: A Simple Qualitative Approach

“…Various laboratory-focused tools and methodologies for completing a safety risk assessment have been published, yet few similar resources to address chemical security exist . Several security risk-related research papers for chemical plants and the process industry are available, − but as the US Chemical Safety Board has noted, industrial guidelines and approaches do not always lend themselves to be directly applied to academic institutions . This paper presents a simple qualitative security risk assessment approach that has been applied at a university in a developing country.…”
