In developing distributed real-time systems, it is necessary to verify that latency of end-to-end computations meets timing constraints. Therefore, it is important to analyze latency of end-to-end computations. These days, a stochastic analysis method for response times of real-time systems is proposed using random execution times of tasks. In general, it becomes a problem that a stochastic analysis takes long time because of complexity. In this paper, we propose a stochastic analysis method for both of response times of tasks and end-to-end latency, using random execution times and random initial phases of tasks. By using the method, analysis time is drastically reduced by focusing only on analyzing the end of the response time distribution.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告組込みシステム（EMB）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2010-08-02","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"2010-EMB-18"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"updated":"2025-01-21T23:35:42.643368+00:00","links":{}}
