Abstract:The design of fault trees is standardized and not using its full potential in conveying important information. Fault trees are commonly used in reliability engineering. This model is used to investigate possible failures in systems such as airplanes, software or nuclear power engineering. In this study we propose a new design for this visualization which is more intuitive and understandable. The design will not only be able to describe the qualitative relationships between subsets, but also its quantitative properties. This new design will be used in explaining fault tree mechanics to non-experts. Based on a literature review of visualization techniques and an inspection of existing fault tree designs, a new design will first be designed in Adobe Illustrator. This design will subsequently be realized in the form of an interactive web application written with the p5.js library. Expert opinions are used throughout the whole designing process to ensure that all the information of the regular fault tree is used in a correct way in the new design. And to ensure that the tool is useful to the experts when they need to explain fault tree mechanics. This process resulted in an innovative fault tree design that, according to the consulted experts, puts fault trees in a new and more understandable perspective.
