Fault tree analysis is often used to assess risks within industrial systems. The technique is commonly used although there are associated limitations 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 Binary Decision Diagram (BDD) methodology. To utilise the technique the fault tree str...

This paper presents advanced features of a fault tree solver FTREX (Fault Tree Reliability Evaluation eXpert). Fault tree analysis is one of the most commonly used methods for the safety analysis of industrial systems especially for the probabilistic safety analysis (PSA) of nuclear power plants. Fault trees are solved by the classical Boolean algebra[1,2], conventional Binary Decision Diagram ...

A new hazard analysis technique, called System-Theoretic Process Analysis, is capable of identifying potential hazardous design flaws, including software and system design errors and unsafe interactions among multiple system components. Detailed procedures for performing the hazard analysis were developed and the feasibility and utility of using it on complex systems was demonstrated by applyin...

Fault Tree Analysis is a well-known method for reliability evaluation of systems. However, manual construction of fault trees is a tedious and time-consuming task. Thus, many researchers tried to get benefit of high speed and accuracy of digital computers to automate this process. Automated construction of fault trees can be very useful in system reliability analysis, especially in design step,...
