Statistics Seminars: Ternary Decision Diagrams for the Real-time Analysis of Non-coherent Fault Trees
6 November 2007 14:15 in CM221
Risk and safety assessments performed on potentially hazardous industrial systems commonly utilise Fault Tree Analysis (FTA) to forecast of the probability of system failure. In non-coherent fault trees components' working states as well as components' failures contribute to the failure of the system. It is known that the Binary Decision Diagram (BDD) method can improve the accuracy and efficiency of the quantitative analysis of non-coherent fault trees. This talk demonstrates the value of the Ternary Decision Diagram method (TDD) for the qualitative analysis of non-coherent fault trees. The approach is useful in applications for autonomous systems when the decision making process is based on the real-time analysis of fault trees converted to TDDs.
