Fault Tree Analysis (FTA) as a Probabilistic Risk Assessment (PRA) method is used to identify basic causes leading to an undesired event, to represent logical relation of these basic causes in leading to the event, and finally to calculate the probability of occurrence of this event. To conduct a quantitative FTA, one needs a fault tree along with failure data of the Basic Events (BEs). Sometim...

Abstract The dependability occupies a strong place in the performance achievement of system. It describes mechanisms that lead to failures systems. Failure mode and effects, analysis (FMEA) is classical safety technique widely used several critical industries. This method uses risk priority number (RPN) assess criticality value prioritize failure modes. However, it suffers from some drawbacks r...

Super MD Tile Factory is an individual business that engaged in the production of tiles small quantities. One products produced Mantili tile with make to stock and order systems. Defective process cannot be completely avoided. The company sets a tolerance for defective production, which 4.44%, but practice can reach 8%. Types defects such as porous, cracked, broken, cracked tiles, charred.The w...

Nowadays the reliability of the logistics in Supply Chain (SC) is realized as an important factor in order to provide high quality of service to customers. The trend of globalization and the development of the communicational technique led to the needs of the high quality of logistics service and the complexity of supply chain. In fact, the better service that customers require, the more import...

The concept of software failure mode and effects analysis (FMEA) has grown in attractiveness over recent years as a way of assessing the reliability of software. Like its hardware counterpart, software FMEA is immensely tedious for an engineer to perform, as well as being error-prone. This paper presents the implementation of a novel method for automating code-level software FMEA based on treat...

When the failure probability of a system is extremely small or necessary statistical data from the system is scarce, it is very difficult or impossible to evaluate its reliability and safety with conventional fault tree analysis (FTA) techniques. New techniques are needed to predict and diagnose such a system’s failures and evaluate its reliability and safety. In this paper, we first provide a ...

Fault Tree Analysis (FTA) attempts to model and analyse failure processes of engineering and biological systems. FTA is basically composed of logic diagrams that display the state of the system and is constructed using graphical design techniques. Originally, engineers were responsible for the development of Fault Tree Analysis, as a deep knowledge of the system under analysis is required. Faul...

PURPOSE Gamma Knife radiosurgery is a highly precise and accurate treatment technique for treating brain diseases with low risk of serious error that nevertheless could potentially be reduced. We applied the AAPM Task Group 100 recommended failure modes and effects analysis (FMEA) tool to develop a risk-based quality management program for Gamma Knife radiosurgery. METHODS A team consisting o...
