Formal system interactive failure analysis method based on systems theoretic process analysis model

摘要

Interactive failures are failures caused by two or more components that often occur in complex systems when the system is modified, upgraded, or simply designed inadequately. However, the official guideline provided, namely, common cause analysis, cannot discover these problems. It cannot establish a complex interactive system model, nor can it provide a unified analysis method for all parts of the system. Another method, systems theoretic process analysis, is limited to the control system.
