| Abstract(in English) | In recent years, auto-sleep functions for hard disk drives or video display units of computer systems have been paid much attentions in term of the power saving. In this paper, we consider the problem when one should switch the system to a sleep mode, and propose a stochastic model to derive the optimal sleep time under a criterion called power effectiveness. In particular, we assume that access requirements are cancelled when the system has serviced an other access requirement. In the case that the access requirements occur in accordance with homogeneous Poisson process, the optimal sleep time which maximizes the power effectiveness is analytically derived. For more general cases, two kinds of approximated solutions are provieded. |
