Towards this evaluation method, the expected reliability index is modelled as a reliability grasping technique using Bayesian analysis that integrates reliability and confidence level. The Bayesian method is applied to the uncertainty evaluation of unknown parameters to define the Bayesian expected reliability as a unitary reliability index for the allowable material strength. The construction of the Bayesian reliability method and a concrete evaluation example for the MIL value of the material strength are shown in using MCMC (Markov chain Monte Carlo) which is a representative method of calculation statistics.","subitem_description_type":"Other"}]},"item_3_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: 図版あり","subitem_description_type":"Other"}]},"item_3_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains illustrations","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA1830027000","subitem_description_type":"Other"}]},"item_3_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-RM-18-011","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構(JAXA)"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_3_source_id_22":{"attribute_name":"ISSNONLINE","attribute_value_mlt":[{"subitem_source_identifier":"2433-2224","subitem_source_identifier_type":"ISSN"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙航空研究開発機構航空技術部門構造・複合材技術研究ユニット(JAXA)"},{"subitem_text_value":"宇宙航空研究開発機構航空技術部門構造・複合材技術研究ユニット(JAXA)"},{"subitem_text_value":"株式会社IHIジェットサービス"},{"subitem_text_value":"宇宙航空研究開発機構航空技術部門構造・複合材技術研究ユニット(JAXA)"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Structures and Advanced Composite Research Unit, Aeronautical Technology Directorate, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Structures and Advanced Composite Research Unit, Aeronautical Technology Directorate, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"IHI Jet Service Co., Ltd."},{"subitem_text_language":"en","subitem_text_value":"Structures and Advanced Composite Research Unit, Aeronautical Technology Directorate, Japan Aerospace Exploration Agency (JAXA)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"伊藤, 誠一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"加藤, 久弥"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"原, 栄一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"岡田, 孝雄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ito, Seiichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kato, Hisaya","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hara, Eiichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Okada, Takao","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-15"}],"displaytype":"detail","filename":"AA1830027000.pdf","filesize":[{"value":"1.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA1830027000.pdf","url":"https://jaxa.repo.nii.ac.jp/record/2432/files/AA1830027000.pdf"},"version_id":"3ee22ff4-0eaf-4c1f-88ef-c6359db0816d"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"構造安全性・信頼性","subitem_subject_scheme":"Other"},{"subitem_subject":"ベイズ期待信頼度","subitem_subject_scheme":"Other"},{"subitem_subject":"MCMC法","subitem_subject_scheme":"Other"},{"subitem_subject":"MIL-A/B値","subitem_subject_scheme":"Other"},{"subitem_subject":"AIC","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"強度不確定性に対する簡易評価指標: MCMCに基づくベイズ期待信頼度","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"強度不確定性に対する簡易評価指標: MCMCに基づくベイズ期待信頼度"}]},"item_type_id":"3","owner":"1","path":["1098","1893"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-02-15"},"publish_date":"2019-02-15","publish_status":"0","recid":"2432","relation_version_is_last":true,"title":["強度不確定性に対する簡易評価指標: MCMCに基づくベイズ期待信頼度"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T09:22:44.993496+00:00"}
