  • Integrated electronic documentation for decision support in safety-critical plant operations

    Publication Year: 1992, Page(s):8/1 - 8/3

    Due to the nature of petrochemical plants, automation alone cannot minimise the risk of safety-critical incidents. When addressing hazard management, people issues, the information needs of decision makers, in particular those of the operators, the integrity of plant documentation, and management concerns need to be considered in an integrated way, with computer software used as a means to impleme...

    A number of safety assessments have been carried out for programmable electronic systems over the last seven years at ERA. In the course of this work, significant problems have been observed with the construction of an appropriate safety case. Some of the problems have been of a philosophical nature, while in some cases they have been of a detailed nature. The author has been involved in developin... View full abstract»

    Outlines a procedure for methodically evaluating the level of hazard which any feature in IT hardware presents to the user or service engineer. By independently assessing the various contributory factors and applying them to a specially designed chart, it is possible to determine if the hazard is 'extreme'.<<ETX>> View full abstract»

  • Hazard and operability study as an approach to software safety assessment

    Publication Year: 1992, Page(s):5/1 - 5/3

    Hazard and operability study (HAZOP) is an analytical technique that uses the imagination and experience of experts to identify potential accidents. Lloyd's Register has used HAZOP techniques for many years and is now focusing its attention on the application of this method to computer systems. This paper is a review of the HAZOP method and specific experience related to software assessment. The s... View full abstract»

  • A case study of automatic landings

    Publication Year: 1992, Page(s):3/1 - 3/4

    The case study described is over 20 years old, but it is not just of historic interest: the pioneering techniques used are still applicable and similar problems still await analysis. Above all, it is not often that one has the opportunity of looking back 20 years with the benefit of hindsight and still being able to benefit from the experience. The case study was a 'safety study', which would toda... View full abstract»

    Existing techniques only address parts of the problem of assessing the safety of the software components of safety-critical systems. The main shortcomings of these existing techniques lie in their poor integration with each other and with the rest of the development process. The authors have identified three main areas where improved integration is necessary-semantic, procedural and operational in... View full abstract»

  • Hardware reliability

    Publication Year: 1992, Page(s):1/1 - 1/4

    Hardware and software failures cannot be considered alone when addressing the integrity, or the availability, of programmable equipment. Software features can affect hardware reliability as in the case of auto-test software which reveals dormant hardware faults. Hardware, on the other hand, can affect the outcome of software failures on a system through its configuration and timing related feature... View full abstract»
