Failure Mode and Effect Analysis (FMEA) is a key risk management tool used in detecting and eradicating potential failure for the purpose of improving the reliability and safety of a system. However, the traditional FMEA in spite of its popularity has inadequacies that have hindered the effectiveness of the tool in analyzing risk of failure modes. Due to the shortcomings of the technique, different improved versions have been suggested in the literature in order for risk to be analysed more effectively but majority of these versions are computationally challenging. In this paper, a simple approach is in troduced for improving the risk analysis capability of the FMEA. The approach utilizes Evaluation based on Distance from Average Solution (EDAS) as an alternative to RPN of FMEA in analyzing risk of failure. A case study of the turbocharger system of a diesel engine is applied to demonstrate the usefulness of the method. The result obtained from the EDAS method were compared with approaches in the literature previously used to address risk analysis of a turbo charger. The result of the analysis indicated that the EDAS method is a feasible alternative technique for risk analysis.

Purpose: of the current research is to develop a reliability assessment method with an extension of the existing ones and pooling them to a common framework. The system must identify the most unreliable parts of a production process and suggest the most efficient ways for the reliability improvement. Design/methodology/approach: FMEA is in the centre of the proposed framework,a reliability analysis type, the most widely used in enterprises. The current research suggests to extend the FMEA by introducing a classification of faults. In this procedure, Bayesian Belief Network is employed to analyze faults. Findings: An integrated modelling method based on a system modelling and complemented with a reliability evaluation mechanism has the capability to analyse and design manufacturing systems. The tool developed to analyse a production process, enables companies to analyse the process as a whole as well as its parts and achieve efficient prognosis for the production process reorganization. Research limitations/implications: The reliability analysis framework is developed for machinery manufacturing enterprises. Practical implications: The reliability assessment tool helps engineers quickly and with accurate estimate most unreliable places of production process and indicates ways of their elimination with great efficiency. Originality/value: Expansion of FMEA method, application of Bayesian Belief Network for process reliability estimation, usage of reliability estimation during production route creation.

Metoda FMEA sama w sobie przynosi duże efekty, jednak nie rozwiąże wszystkich problemów związanych z wyrobem. Najlepiej stosować ją w połączeniu z innymi narzędziami zarządzania jakością, na przykład metodą QFD.

EN

The FMEA-method itself is very beneficial tool for companies, but it doesn't solve all problems related to the product. The best performance would be based on the use of it in cooperation with other quality tools, e.g. with QFD (Quality Function Deployment), and so on. The FMEA-analysis helps significantly in the evaluation of quality costs and in the reduction of them. But in the same time it causes the growth of other quality costs elements. In investigation realized by authors was noticed an increase of 9% in testing and evaluation process. The preventive costs increased 11% as well. But the final and general effect was positive. It evidences the usefulness of methodology in practical approach, Some conclusions are linked with better awareness of employees, because the training costs increased 6% too, resulting even positively. All problems, related to the research realized in national companies, are in the publication demonstrated. The discussion of results obtained is presented and analyzed.

Zasadniczym celem systemu bezpieczeństwa jest uzyskanie pewności działania, zgodnego ze specyfikacją wymagań oraz zawarcie go w postępie technologicznym, w sposobie działania i w projektowaniu: systemów, podsystemów, wyposażenia, urządzeń i ich połączeń. Formalny program oceny bezpieczeństwa z wyprzedzeniem identyfikuje krytyczność zagrożenia, aby można było przez odpowiednie działania doprowadzić do wyeliminowania lub redukcji związanego z tym ryzyka do akceptowanego poziomu. Jest to zasadniczy wkład w skuteczność zapewnienia bezpieczeństwa. Efektywność systemu bezpieczeństwa zależy w głównej mierze od tego jakie cele i wymagania są stawiane w zakresie bezpieczeństwa. Rosnące wymagania dotyczące oczekiwanego bezpieczeństwa samolotów mogą być spełnione przy zastosowaniu odpowiednich systemów, doskonalenia procedur projektowania i nowoczesnych metod analizy bezpieczeństwa. W pracy omówiono wybrane metody analizy bezpieczeństwa: FMFA (Failure Mode and Effect Analysis) oraz analizę drzewa uszkodzeń - FTA (Fault Tree Analysis).

The principle objective of a system safety program is to make sure safety, consistent with mission requirement, is inluded in technology development and designed into systems, subsystems, equipment facilities, and their interfaces and operation. A formal safety program that stress early hazard identification and elimination or reduction of associated risk to a level acceptable to the managing activity is the principal contribution of effective system safety. The succes of the system safety effort depends on definitive statement of safety objectives and requirements. Growing demands on aircraft safety can be fulfilled only by application of apriopriate systems, safety analysis methods and designing improvement methods. The paper presents safety analysis methods: Failure Mode and Effect Analysis (FMFA) and Fault Tree Analysis (FTA).
