In this paper the authors propose computerized support for Fault Tree Analysis (FTA) based on new knowledge management in product design. FTA is a method of analyzing and visualizing the causes of a fault event by Fault Tree diagram (FT diagram) that has a tree structure with logical step. When we develop the new product, we use FTA to analyze the fault events, to extract design parameters, and to plan test programs in Jatco's development process. Although FTA is an effective analytical tool for resolving problems, improving design quality and planning test programs, it is not easy to complete the FT diagram of a fault on Automatic Transmission and the component system without a mistake. To solve this problem, we propose the following approach using Computer-Aided knowledge management based on Quantity Dimension Indexing and block diagram. We classify FT diagrams into component failure, system failure, and control failure diagrams.
