This paper discusses safety analysis of design documents constructed by object-oriented development approaches. In our previously proposed method, whether design documents satisfy safety requirements is checked using some information tables, and these safety requirements are assumed to be given in advance. However, any systematic method that can derive such safety requirements from requirements specification and safety standards has not been developed. To overcome this problem, we propose a new FTA (Fault Tree Analysis)-based technique to derive safety requirements from requirements specification, component library, and design documents. Then, we apply the proposed method to typical examples taken from previous reports.
