Model-Based FMEA & FTA with Case-Based Reasoning

The main challenge of performing safety & reliability analysis in multi-disciplinary products is the lack of information and knowledge within an organization to guide them in the beginning. In fact, such knowledge can be extracted and consolidated from historical data, technical experiences, and system architectures. This paper proposes an approach to leverage the value of system architecture models, safety & reliability models, and the CBR method to enable a systematic, adaptive, and multi-disciplinary knowledge management system. As a result, the engineers can retrieve and reuse the information from historical failures to guide their analysis in their existing or new product development. To improve the knowledge in CBR casebase, this paper demonstrates a conceptual idea to leverage the values of FMEA-FTA integration and SysML relationships. The idea enables a broader analysis and more systematic way for information correctness.
