This paper adresses a problem of how to determine the optimal sleep timing when the computer user should turn the hard disk or the display off in order to save the electric power after the computer has not been accessed. We propose a stochastic model to obtain the optimal sleep timing strategy which minimizes the expected power consumed per unit time in the steady-state, when the access requirements arrive at a computer according to a renewal process. In this model, if the first transaction is accessed, the other transactions arrived later are cummulated in a buffer until completing the process of the first one. We derive the optimal auto-sleep strategy analytically when the access requirements arrive in accordance with a homogeneous Poisson process and the buffer behaviour follows an M/G/1 queueing process, and provide three approximated solutions for more general cases.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"1040","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"1027","bibliographicIssueDates":{"bibliographicIssueDate":"1999-03-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"40"}]},"relation_version_is_last":true,"item_2_alternative_title_2":{"attribute_name":"その他タイトル","attribute_value_mlt":[{"subitem_alternative_title":"オペレーションズリサーチ"}]},"weko_creator_id":"1"}}
