Bayesian Networks Applications in the Reliability of Software Systems for Monitoring Electrical Substations

General aspects regarding software quality are discussed. The analysis of quality aspects is made for a software monitoring system of an electrical substation. Mathematical models are proposed to ensure software quality including Bayesian networks, Markov chains. Using a monitoring system developed in Romania as case study, we proposed modelling this system using SCL language and Bayesian networks in order to estimate its reliability. Some software modules were developed in order to implement the mathematical models proposed.
