چکیده

Soft errors due to cosmic particles are a growing reliability threat to information systems. In this work, a methodology is developed to analyze the effects of single event upsets (SEU) and obtain Failure In Time (FIT) rates for commercial server microprocessors in live information systems. Our methodology is based on data collected from error logs and error traces of the microprocessors collected from systems in the field. Soft errors are further localized within the microprocessor resources with the assistance of the machine check architecture.

Systems Risk Analysis UsingHierarchical Modeling

A fresh look at the system analysis helped us in finding a new way of calculating the risks associated with the system. The author found that, due to the shortcomings of RPN, more researches needed to be done in this area to use RPNs as a new source of information for system risk analysis. It is the purpose of this article to investigate the fundamental concepts of failure modes and effects ana...

Tackling uncertainty in safety risk analysis in process systems: The case of gas pressure reduction stations

Industrial plants are subjected to very dangerous events. Therefore, it is very essential to carry out an efficient risk and safety analysis. In classical applications, risk analysis treats event probabilities as certain data, while there is much penurious knowledge and uncertainty in generic failure data that will lead to biased and inconsistent alternative estimates. Then, in order to achieve...
