Modular Approach for Probabilistic Safety Assessment of Systems with Multiple Failure Modes

Reliability Analysis of K-Out-Of N: G Machining Systems with Mixed Spares and Multiple Modes of Failure (TECHNICAL NOTE)

This paper deals with the transient analysis of K-out-of-N: G system consisting of Noperatingmachines. To improve system reliability, Y cold standby and S warm standbys spares areprovided to replace the failed machines. The machines are assumed to fail in multiple modes. At leastK-out-of-N machines for smooth functioning of the system. Reliability and mean time to failure areestablished in term...

Reliability Analysis of Component-Based Systems with Multiple Failure Modes

This paper presents a novel approach to the reliability modeling and analysis of a component-based system that allows dealing with multiple failure modes and studying the error propagation among components. The proposed model permits to specify the components attitude to produce, propagate, transform or mask different failure modes. These component-level reliability specifications together with...

Improved Approach for Estimating Leak and Break Frequencies of Piping Systems in Probabilistic Safety Assessment

The estimation of leak and break frequencies in piping systems is part of the probabilistic safety assessment of technical plants. In this paper, the statistical method based on the evaluation of the German operational experience for piping systems with different diameters is described because an earlier estimation has been updated and extended introducing new methodical aspects and data. Major...

Simulation of Characteristic of Linear Degradation with Failure Modes

Reliability and Diagnostics of Modular Systems: a New Probabilistic Approach

Reliability theory and model-based diagnostics are two different, although closely related fields. Both have their own well-developed techniques and computational models, but their connection is rarely being pointed out. This paper starts from a common modular system description, whose underlying Boolean function is transformed into a compact graphical representation. The goal is to show how to...
