Extend STPA method using hybrid dynamic theory

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

STPA is based on system theory and control theory and has many advantages in safety analysis. Hybrid dynamic theory has a wide range of engineering application, especially in control filed. Therefore, we attempt to use the hybrid dynamical theory to extend STPA method. STPA model is transformed into the hierarchical hybrid model based on hybrid dynamic theory. The extended model is described by a septuple. The constraints and failure modes of extended method is also proposed. At last, the train door example is used to explain the extended method.
