Abstract: Ensuring and strengthening the reliability,security and stability of computer systems are advanced requirement to system service.Based on autonomic computing,a self-tuning model on system dependability is proposed.By dynamically analyzing the change trend of object system dependability,and making reference to the grads fluctuation of accient dependability curve,it implements the on-line dependability evaluation,dependability dynamic prediction and self-tuning scheme selection in turn,which accomplishes the self-tuning function of system dependability.Confidence field grads calculation method is adopted to solve the optimization problem of self-tuning.
