The system needs of growing systems including heterogeneous functions and operations are increased. A high assurance system that achieves high reliability and high availability is very important for such systems. In order to realize a high assurance system, we developed assurance technology based on ADS (Autonomous Decentralized System). When a growing system changes or grows, its reliability may be lowered. The authors clarify the risk factors which lower the reliability and quality of a growing system when the system is modified. We examine the technology to eliminate or mitigate those risk factors, and propose adaptive assurance technology that can minimize the risk. We also applied this technology to ATOS (Autonomous Decentralized Transport Operation Control System) for the Tokyo Metropolitan Railway Network as an example of a really changing and growing system and mention its effectiveness.
