Dynamic Safety Analysis CNG Stations Using Fault Tree Approach and Bayesian Network

Introduction: The safety of CNG stations is important because of their location in urban areas, as well as to prevent accidents and to protect the safety of personnel, property, and environment. An event occurrence analysis with probability updating is the key to dynamic safety analysis. Methods and materials: In this study, the Failure Modes and Effects Analysis (FMEA) technique was used to d...

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. Benchmarks show a gain of more than two orders of magnitude in terms of state space generation and a...

A Dynamic Fault Tree Analysis Model

In this paper a model for dynamic fault tree (FT) analysis is developed. The model is ussed for the analysis of a cold standby redundant system. It is shown that a typical modern fault tree analysis (FTA), resulting in the Boolean domain in a short pseudopolynomial, i.e., a polynomial in the literals of the FT input variables, can yield grave errors in case of cold standby, even though the sing...

Dynamic DEA: A Hybrid Measure Approach

 In the real world applications, there are some situations where inputs and outputs are time-dependent and are affected during the production periods. Capital stock can be seen as an effective instance in such occasions. In order to handling long-time planning, dynamic structure was proposed in efficiency evaluation. In this framework, there are some of the inputs and outputs change proportiona...

A Hybrid Approach for Fault Tree Analysis Combining Probabilistic Method with Fuzzy Numbers

Conventional fault tree analysis in safety analysis of complex engineering systems calculates the occurrence probability of the top undesired event using probabilistic failure rates. However, it is often very difficult to obtain those failure rates well in advance due to insufficient data, environment changing or new components. Fuzzy numbers can be applied to estimate failure rates by handling...
