¿µ¹®³»¿ë¿ä¾à CPS is used in various fields such as smart manufacturing, smart energy, and smart city, and its application scope is gradually expanding. In particular, the development of intelligent information technologies such as IoT, AI, and Bigdata has enabled new interactions between the physical and cyber worlds.
However, there are a variety of risks in CPS, such as external environmental factors, operator misbehavior, and defects inherent in the system. This is a major cause of system malfunction and can lead to serious accidents, such as unexpected life and property damage. In particular, malfunctions of safety-critical systems used in fields such as automotive, aerospace, railroads, nuclear power, etc. are enormously damaged because they are directly related to social chaos and safety accidents.
In order to minimize the occurrence of accidents, it is necessary to actively assure trustworthiness that analyze the interaction and influence on risk factors. Moreover, in complex systems such as CPS, it is more efficient in terms of maintenance costs to perform safety and reliability activities from the early stage of system development.
CPS requires a new model that complements existing system analysis techniques due to the complexity of the components and various variables that lead to uncertainty. The CPS Accident Analysis Model assure trustworthiness of CPS by analyzing the risk factors that cause an accident from various logically viewpoints and by supporting the establishment of countermeasures against them.
