STPA guided systems engineering

Abstract

Today systems become more and more complex and networked. This increasing complexity requires new methods for systems engineering. In addition, with the number of internal or external components the probability of faulty components within systems increases. At every point of time, some component may be faulty or does not deliver the desired function. This paper presents a new design methodology to design systems that can handle the mentioned issues of the systems by design. The new methodology is based on System-Theoretic Process Analysis and standard systems engineering methods.
