Evaluation of Intelligent Systems for the Utilisation of HAZOP Analysis Results
2007In every industry sector, companies need to find ways to operate profitably and safely. Risk management offers a way of combining profitability and responsibility. However, no industrial company can afford to spend extensive amounts of time and money on safety and reliability studies — the collection of data and the preparation of the relevant ...

A systematic formulation for HAZOP analysis based on structural model
Reliability Engineering and System Safety, 2014Abstract The combination of an automatic HAZOP analysis with a structural model was introduced to obtain a systematic procedure for hazard and mal-operations identification. There are three stages of the proposed procedure. The first stage was used to analyze the conventional hazard and mal-operations for each process unit, whereas the second stage ...

A knowledge‐based framework for automating HAZOP analysis
AIChE Journal, 1994AbstractHazard and operability (HAZOP) analysis is the study of systematically identifying every conceivable abnormal process deviation, its abnormal causes and adverse hazardous consequences in a chemical plant. HAZOP analysis is a difficult, time‐consuming, and labor‐intensive activity. A automated HAZOP system can reduce the time and effort involved

Experience with an expert system for automated HAZOP analysis
Computers & Chemical Engineering, 1996Hazard and Operability (HAZOP) analysis is the most widely used and recognized as the preferred safety analysis approach in the chemical process industry. A model-based framework and an expert system called HAZOPExpert has been developed recently for automating this analysis.

Effective Security Requirements Analysis: HAZOP and Use Cases
2004Use cases are widely used for functional requirements elicitation. However, security non-functional requirements are often neglected in this requirements analysis process. As systems become increasingly complex current means of analysis will probably prove ineffective.

Hazop Analysis Applied on Critical Milling Operations
IFAC Proceedings Volumes, 1998Abstract Restarting of machine tools after undesired stops is a critical operation that often leads to damage of the workpiece or machine tool, and thereby causing significant costs. This paper describes how the Hazard and Operability (HAZOP) Analysis technique can be used to identify potential deviations of a restarting procedure in a milling ...

Digraph-based models for automated HAZOP analysis
Reliability Engineering & System Safety, 1995Hazard and operability (HAZOP) analysis is a systematic hazard identification procedure for predicting the various adverse consequences that might arise in a chemical plant due to abnormal causes. HAZOP analysis is typically performed by a group of experts by systematically considering all possible deviations from normal behavior of a process plant ...

Application of HAZOP Analysis Method in Vehicle Amusement Facilities
2020 3rd International Conference on Electron Device and Mechanical Engineering (ICEDME), 2020Problems in car rides often lead to more serious consequences, and cause social stability adverse effects. The safety of amusement facilities has always been the most important part in the design, construction and operation of amusement facilities. Therefore, starting from the safety issues of the amusement facilities, the HAZOP analysis method was ...

Hazard Analysis Using HAZOP: A Case Study
1993There is an increasing use of computing in safety related applications and ensuring that such systems are conceived, designed and produced with appropriate attention to safety is not easy. The process of identifying undesirable events and their consequences is known as hazard analysis.

Qualitative models of equipment units and their use in automatic HAZOP analysis
Reliability Engineering & System Safety, 2000Abstract The use of qualitative models in a support system for HAZOP analyses, in connection with an algorithm for finding the causes and the consequences of variable deviations, is described. The models use several representation structures among which mini-trees constitute the most important from the logical-functional point of view.
