Self-adaptive software is considered as the most advanced approach and its development attracts a lot of attention. Decentralization is an effective way to design and manage the complexity of modern self-adaptive software systems. However, there are still tremendous challenges. One major challenge is to unify decentrality with traditional self-adaptive implementation framework during design and implementation activity. One is to guarantee the required global goals and performance of decentralized self-adaptive systems operating in highly dynamic and uncertain environments. Another challenge is to predict the influence of system's internal change on its self-adaptability to the environment. To solve these problems, we combine the mechanisms of separation of concerns with modeling method using timed automata to allow the system to be analyzed and verified. Timed computation tree logic is used to specify system goals and stochastic simulations in dynamic environment are experimented to verify decentralized self-adaptive system's adaptation properties. In this paper, we extracted a motivation example from practical applications in UAV emergency mission scenarios. The whole approach is evaluated and illustrated with this motivation example and the statistical results can be used as reference for arrangement planning of UAVs in cyber physical spaces.
