We present a graphical toolset for verifying AADL models, which are gaining widespread acceptance in aerospace, automobile and avionics industries for comprehensively specifying safety-critical systems by capturing functional, probabilistic and hybrid aspects. Analyses are implemented on top of mature model checking tools and range from requirements validation to functional verification, safety...

M. Roszak, M. Spilka, A. Kania, Silesian University of Technology, Institute of Engineering Materials and Biomaterials, Gliwice, Poland The purpose of this paper is to present a concept of FMEA analysis for environmental aspects, together with a discussion of the importance, implementation and application of the proposed concept. The analyses and the developed E-FMEA methodology have resulted i...

Failure mode and effects analysis (FMEA) is one of the well-known techniques of quality management that is used for continuous improvements in product or process designs. While applying this technique, determining the risk priority numbers, which indicate the levels of risks associated with potential problems, is of prime importance for the success of application. These numbers are generally at...

BACKGROUND Intravenous potassium chloride (IV KCl) solutions are widely used in hospitals for treatment of hypokalemia. As ampoules of concentrated KCL must be diluted before use, critical incidents have been associated with its preparation and administration. Currently, we have introduced ready-to-use diluted KCl infusion solutions to minimize the use of high-alert concentrated KCl. Since this...

Some results of the implementation of a new support tool for automated hazard analysis are presented in this paper. We describe in detail the further progresses on the application of intelligent systems to the hazard analysis and especially to the HAZOP and FMEA analysis. A previously developed program, that allows the automatic generation of the report of the HAZOP analysis as regards the dete...

Limitations in scope but also difficulties with the efficiency and scalability of present algorithms seem to have so far limited the industrial uptake of existing automated FMEA technology. In this paper, we describe a new tool for the automatic synthesis of FMEAs which builds upon our earlier work on fault tree synthesis. The tool constructs FMEAs from engineering diagrams (e.g. developed in M...

Nowadays safety at workstations is so important for managers and they try to ensure that workstations meet minimum requirements. There are some research about using FMEA (Failure mode and effects analysis) to increase the safety at work especially in food industries and hospitals, but all of them have concentrated on safety in special points of view and they are not applicable for all fields. I...

Failure mode and effects analysis (FMEA) has been extensively used for examining potential failures in products, processes, designs and services. An important issue of FMEA is the determination of risk priorities of the failure modes that have been identified. The traditional FMEA determines the risk priorities of failure modes using the so-called risk priority numbers (RPNs), which require the...

The simultaneous generation of steam and power, which is commonly referred to as cogeneration, has been adopted by many sugar mills in India to overcome the power shortage. It becomes an increasingly important source of income for sugar factories. The problems faced by the sugar mill industry arise mainly due to failures of either the complete system or some specific components during the cogen...

PURPOSE/OBJECTIVES To assess and improve the safety of hospital-based adult chemotherapy administration. DESIGN Prospective, systems-focused clinical risk assessment. SETTING An adult inpatient and outpatient oncology unit in a large urban hospital in the United Kingdom. SAMPLE 8-person nurse-led multidisciplinary team, which included managerial staff and patient safety researchers. MET...
