Today huge capacity sea-going vessels are propelled by mega high-powered marine diesel ?engines, referred to as Main Engine. Turbocharging system is an integral part of large engine plant, ?contributing their safety, reliability, and efficiency. Defects in the turbocharging ?could result higher fuel consumption, erratic running Engine, worst ?scenario may stoppage Engine at sea. An inefficient ...

Reliability is one of the key problems of an automatic system, especially to the huge, complex, multiple target-based, safety critical and reliability-dependent train control system. A system reliability analysis method based on a dynamic fault tree was proposed to analyse possible fault causes of a whole system in a HLA (High Level Architecture) simulation platform, and according to the princi...

Fault Tree Analysis is a traditional deductive safety analysis technique that is applied during the system design stage. However, traditional fault trees often suffer from a lack of formal semantics to check the correctness or consistency of the descriptions. This is especially a problem in safety-critical system analysis. To overcome this limitation, we propose a novel formal fault tree constr...

In this paper, according to theoretical diagnosis of fault tree, the author builds a diagnosis model based on dynamic fault tree and illustrates the model’s construction method and diagnosis logic in detail. According to case analysis, compared with conventional fault tree diagnosis, the above-mentioned method is advanced in fault-tolerant ability. Plus, the diagnosis results record some interm...

Fault-tree analysis is commonly used for risk assessment of industrial systems. Several computer packages are available to carry out the analysis. Despite its common usage there are associated limitations of the technique in terms of accuracy and efficiency when dealing with large fault-tree structures. The most recent approach to aid the analysis of the fault-tree diagram is the BDD (binary de...

We propose FTA, a programming model that provides failure localization and transparent recovery of process failures in MPI applications.

We have presented trapezoidal intuitionistic fuzzy number. Arithmetic operations of trapezoidal intuitionistic fuzzy number is presented based on (α, β)-cuts. We have presented intuitionistic fuzzy fault tree analysis using trapezoidal intuitionistic fuzzy number. In application of intuitionistic fuzzy fault tree analysis, we have computed failure of fire protection system taking failure of eac...

The increasing reliance on computer technology nowadays has resulted in a rapidly growing need to build reliable and fault resistant computer-based systems. Computer system reliabilities are conventionally modeled and analyzed using techniques such as fault tree analysis (FTA) and reliability block diagrams (RBD), which provide static representations of system reliabilities. A recent extension ...
