Advancing Dynamic Fault Tree Analysis
This paper presents a new state space generation approach for dynamic fault trees (DFTs) together with a technique to synthesise failures rates in DFTs. Our state space generation technique aggressively exploits the DFT structure --- detecting symmetries, spurious non-determinism, and don't cares.

Application of the dynamic FMEA in the reliability analysis of DCS [PDF]
Digital distributed instrumentation and control system (DCS) is critical to the safety of nuclear power plants (NPPs). Static analysis methods developed from analog control system are not applicable to DCS due to its enhanced dynamic interactions and ...

A Modular Approach to Non-deterministic Dynamic Fault Trees [PDF]
Dynamic Fault Trees (DFTs) are powerful tools for deriving fault-tolerant system designs. However, deterministic approaches to DFTs suffer from semantic struggles with problems such as spare races. In this paper, we discuss the added complexity in the state-space representation of a non-deterministic DFT model and propose a modularized approach for ...

The failure that occurs during the dry-type transformer temperature monitoring sensor working will result in wrong data output, which may cause the monitor and monitoring background to respond incorrectly.

Fault estimation and fault-tolerant control for discrete-time dynamic systems [PDF]
In this paper, a novel discrete-time estimator is proposed, which is employed for simultaneous estimation of system states, and actuator/sensor faults in a discrete-time dynamic system.

The safety of nuclear power plants is analyzed by a probabilistic risk assessment, and the fault tree analysis is the most widely used method for a risk assessment with the event tree analysis.

Algebraic determination of the structure function of Dynamic Fault Trees [PDF]
This paper presents an algebraic framework allowing to algebraically model dynamic gates and determine the structure function of any Dynamic Fault Tree (DFT). This structure function can then be exploited to perform both the qualitative and quantitative analysis of DFTs directly, even though this latter aspect is not detailed in this paper.

Data-driven approach to machine condition prognosis using least square regression trees [PDF]
Machine fault prognosis techniques have been considered profoundly in the recent time due to their profit for reducing unexpected faults or unscheduled maintenance.

Dependability assessment is one of the most important activities for the analysis of complex systems. Classical analysis techniques of safety, risk, and dependability, like Fault Tree Analysis or Reliability Block Diagrams, are easy to implement, but ...
