Reliability Analysis of a Web Server by FTA Method

Authors: Gabriel PETRICA, Ionut – Daniel BARBU, Sabina – Daniela AXINTE, Cristian PASCARIU

Published: ADVANCED TOPICS IN ELECTRICAL ENGINEERING – ATEE 2017

“FTA (Fault Tree Analysis) is one of the most used methods for reliability analysis and to quantify the risks associated with the failures of systems. This method performs analysis of the combination of events that can lead to a critical system failure (called Top Event of the designed Fault Tree) and allows calculating the probability of failure. In this paper, has been built the Fault Tree for a Web server considering failures that may occur at hardware level (the basic components for the considered computer system). After realizing the Fault Tree, were made two types of analysis: qualitative (which led to the identification of minimal cut sets) and quantitative (this allowed the calculation of the probability of occurrence of the considered critical event – <<Web server not operational>>.” Read more…
