Title
ETMA: An Efficient Tool for Event Trees Modeling and Analysis
Abstract
Event Tree (ET) analysis is a widely used forward deductive safety analysis technique for decision-making at a system design stage. Existing ET tools usually provide Graphical Users Interfaces (GUI) for users to manually draw system-level ET diagrams, which consist of nodes and branches, describing all possible success and failure scenarios. However, these tools do not include some important ET analysis steps, e.g., the automatic generation and reduction of a complete system ET diagram. In this paper, we present a new Event Trees Modeling and Analysis (εTMA) tool to facilitate users to conduct a complete ET analysis of a given system. Some key features of εTMA include: (i) automatic construction of a complete ET model of real-world systems; (ii) deletion/reduction of unnecessary ET nodes and branches; (iii) partitioning of ET paths; and (iv) probabilistic analysis of the occurrence of a certain event. For illustration purposes, we utilize our εTMA tool to conduct the ET analysis of a protective fault trip circuit in power grid transmission lines. We also compared the εTMA results with Isograph, which is a well-known commercial tool for ET analysis.
