Abstract (in Japanese) (See Japanese page) 
(in English) This paper considers the sensitivity analysis for a self-adaptive system with uncertain parameters. The system behavior is described by a parametric Markov decision process (MDP). The system utility, which is given by the total reward of the MDP model, is formulated to determine the optimal policy (i.e., adaptation logic). In the paper, we consider how to calculate the sensitivity of uncertain model parameters in the self-adaptive system analytically. Particularly, the sensitivity analysis reveals how the changes in the model parameters affect the optimal solution under different environmental conditions.
