Many existing structures are always threatened by various natural hazards including earthquake loads. Actually, those systems constructed prior to 1980 in Japan were designed for a particular seismic load which is smaller than a Level 2 earthquake load. After the 1995 Hyogoken-Nanbu earthquake, revised design guidelines were specified, making old infrastructure design fall below acceptable design limits. It means that these systems are vulnerable to strong earthquakes in the future. In recent years, Japan’s population is shrinking, which has a direct impact into the economy and national budget. In view of this, a more rational decision making process is necessary for future investment of seismic disaster prevention activities of lifeline systems. In which case, maintenance works must be optimized efficiently under the constraint of a limited budget. In order to obtain an optimal solution among several alternatives, adequate information required to make decisions should be provided in the risk management approach. In this case the incremental cost for each seismic investment strategy can be provided in this study. Numerical examples are also provided to demonstrate its applicability.", "subitem_description_type": "Abstract"}]}, "item_5_publisher_36": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "Society for Social Management Systems"}]}, "item_5_source_id_11": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "2432-552X", "subitem_source_identifier_type": "ISSN"}]}, "item_5_version_type_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_version_resource": "http://purl.org/coar/version/c_970fb48d4fbd8a85", "subitem_version_type": "VoR"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Koike, Takeshi"}], "nameIdentifiers": [{"nameIdentifier": "2129", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-02-13"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "SMS06-105.pdf", "filesize": [{"value": "94.6 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 94600.0, "url": {"label": "SMS06-105.pdf", "url": "https://kutarr.kochi-tech.ac.jp/record/792/files/SMS06-105.pdf"}, "version_id": "7a7f7b30-df96-423a-9334-f2888c52f780"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "maintenance investment", "subitem_subject_scheme": "Other"}, {"subitem_subject": "lifeline", "subitem_subject_scheme": "Other"}, {"subitem_subject": "seismic risk", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "conference paper", "resourceuri": "http://purl.org/coar/resource_type/c_5794"}]}, "item_title": "Optimal Investment Strategies for Lifeline Systems Under Seismic Risks", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Optimal Investment Strategies for Lifeline Systems Under Seismic Risks"}]}, "item_type_id": "5", "owner": "2", "path": ["18"], "permalink_uri": "http://hdl.handle.net/10173/1591", "pubdate": {"attribute_name": "公開日", "attribute_value": "2018-02-06"}, "publish_date": "2018-02-06", "publish_status": "0", "recid": "792", "relation": {}, "relation_version_is_last": true, "title": ["Optimal Investment Strategies for Lifeline Systems Under Seismic Risks"], "weko_shared_id": -1}
