Practical experience with the application of HazOp to a software intensive system
نویسنده
چکیده
This paper describes the work done by SINTEF on HazOp on a safety critical, software intensive system and the lessons learned in the process. The lessons concern two areas – the HazOp process and the use of the HazOp to formulate lower level safety requirements. We describe a HazOp process based on system functions instead of the overall system functionality and how to use software related guidewords in order to fill in the HazOp forms. For requirements generation and allocation, we describe the process of construction a FT based on the contents of the HazOp forms and how to perform the probability budgeting.

Experience with the application of HAZOP to computer-based systems
This paper summarises the experience gained from application of Hazard and Operability Studies (HAZOP) and related techniques to four computer-based systems. Emphasis is placed on working practices and the integration of HAZOP-style analysis into a safety-oriented lifecycle. Two of the case studies are described in some detail. An industrial study is used to investigate working practices, highl...
متن کاملOn Attributes of Objects in Object-Oriented Software Analysis
One of the modern paradigms to develop a system is object oriented analysis and design. In this paradigm, there are several objects and each object plays some specific roles. There is a sequence of activities to develop an analysis model. In the first step, we work in developing an initial use case model. Then in the second step, they identify a number of concepts and build a glossary of partic...
متن کاملApplying HAZOP to Software Engineering Models
HAZOP is a powerful hazard analysis technique which has a long history in process industries. As the use of programmable electronic systems becomes more common, it is clear that there is a need for a HAZOP method which can be used effectively with such systems. This paper describes several attempts to derive such a process, and identifies some requirements which must be met by any PES HAZOP pro...

Background and aims: Hazard identification is a critical factor to ensure safe design and operation of systems in the process industries. Process industries are one of the most complex systems, with a variety of equipment, control systems, and executive procedures. In these industries, the use of hazardous materials as raw materials or products is quite common. Interactions between technical co...
متن کاملAssessment of Critical Fire Risks in an Industrial Estate Using a Combination of Fuzzy Logic, Expert Elicitation, Bow-tie, and Monte Carlo Methods
Background and Objective: Industrial estates have been described as highly prone to fire incidents. According to the baseline studies, more than 85% of the industrial accidents occurring in industrial estates during the 80s and 90s were fire incidents affecting more than one factory in 10% of the cases. Materials and Methods: After the identification of 30 high-risk industries in Abbasabad i...
