Fault tree analysis (FTA) is a method to analyze and visualize causes of some fault event by expanding a fault event to its cause events hierarchically and making a tree diagram representing the entire structure of the problem. When a designer finds or encounters some problem during a product design and development process, it is an effective way of achieving security and safety of the product to identify all possible causes of the problem by FTA and fix them. Although FTA is an effective method, it is not easy for a designer to make complete fault tree without any misunderstanding or oversight. In this paper, we propose a computer aid for FTA, such as consistency check of fault tree and node expansion advice, based on quantity dimension indexing.
