Abstract: The software-based systems, alone do not cause any risk; but the risk is posed when the software-based systems are considered in the context of general systems where potential risks or hazards exist. Cyber-physical systems are cited as instances of software-based systems. Nowadays, safety and reliability of cyber-physical systems are considerably important due to the increasing complexity of these systems. Risk management techniques are required to reduce the risk to an acceptable level. Generally, safety and reliability methods are important in a risk management process among them software fault tree analysis (SFTA) and software failure modes and effects analysis (SFMEA) methods can be utilised. The main purpose of this article is to provide a comprehensive survey and evaluation of the currently available approaches for software safety and reliability methods in cyber-physical systems in order to reflect the state of the art of this active area.
Keywords: cyber-physical systems; CPSs; software safety and reliability; software failure modes and effects analysis; SFMEA; software fault tree analysis; SFTA.
