Suokas, J., Heino, P. and Karvonen, I., 1990. Expert systems in safety management. Journal of Occupational Accidents , 12: 63–78. The development of computer support for safety and reliability analysis is reviewed, and the possibilities of knowledge based expert systems in safety management are discussed. Two areas are described in more detail: knowledge based safety analysis in process design, and knowledge based diagnosis and management of process disturbances in operation. Knowledge based safety management is illustrated by two examples. The first one is HAZOPEX expert system aiding hazard and operability studies of process systems. The second example is KRM-information system aiding process operators and engineers in the early identification and management of potentially hazardous disturbances. International trends in using knowledge engineering in safety analysis and management are also discussed.
This paper presents a system approach for action plan management process. Based on systematic usage of risk evaluation, it helps in actions priorities definition. Several organisations generate actions belonging to separate business goals, sometimes contradictory. Moreover, maintenance, quality, process, research and development organisations use different approaches to define actions priorities. In this case study, more than 400 engineers participate in this process and generating between 20 to 50 actions sets monthly (each set can contain around 3 actions). This paper demonstrates that it is possible to unify action plans management. This has been achieved by developing a model of management system integrating several quality methods. The proposed tool enables for local managers to have a clear picture of ongoing and planned actions of their areas. For plant managers, it smoothes the coordination among organizations.
We prove that groups acting geometrically on delta-quasiconvex spaces contain no essential Baumslag-Solitar quotients as subgroups. This implies that they are translation discrete, meaning that the translation numbers of their nontorsion elements are bounded away from zero.
