A potential solution is to reduce the material cost through a structure optimization technique. In this study, the plate material and stiffener types, plate thickness, and plate layout are optimized in order to minimize the cost of materials. The genetic algorithm (GA) is a popular optimization technique for determining design variables. However, the GA is not suitable for dealing with continuously changing design variables, such as plate thickness. Hence, this study proposes a three-stage optimization method that consists of the optimization of plate material and stiffener types, plate thickness, and plate layout. The first and second stages are part of an integrated process called the hybrid GA, which starts with the plate material and stiffener-type selections, and then performs plate thickness optimization. The hybrid GA is effective in simultaneously determining design variables with different characteristics, such as the first - and second-stage problems. The last stage is layout optimization in which the plate material and stiffener types handled in the previous stage are considered to have been decided, thereby resulting in minimal effort during this stage.","subitem_description_language":"en"},{"subitem_description":"We would like to thank Universitas Indonesia under Hibah Publikasi Terindeks Internasional (PUTI) Kolaborasi Internasional (2Q2) Tahun Anggaran 2020 (Grant No. NKB-789/UN2.RST/HKP.05.00/2020) for supporting this research","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"Elsevier"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_source_identifier":"0029-8018","subitem_source_identifier_type":"ISSN"}]},"item_1617187024783":{"attribute_name":"Page Start","attribute_value_mlt":[{"subitem_start_page":"108284"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"2020-11-11","bibliographicIssueDateType":"Issued"},"bibliographicPageStart":"108284","bibliographicVolumeNumber":"219","bibliographic_titles":[{"bibliographic_title":"Ocean Engineering"},{"bibliographic_title":"Ocean Engineering"}]}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_b1a7d7d4d402bcce","subitem_version_type":"AO"}]},"item_1617353299429":{"attribute_name":"Relation","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.oceaneng.2020.108284","subitem_relation_type_select":"DOI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1016/j.oceaneng.2020.108284","subitem_relation_type_select":"DOI"}}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-11-11"}],"displaytype":"simple","fileDate":[{"fileDateType":"Available","fileDateValue":"2022-11-11"}],"filename":"OceanEngineering_219_108284.pdf","filesize":[{"value":"3.7 MB"}],"mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://hiroshima.repo.nii.ac.jp/record/2007897/files/OceanEngineering_219_108284.pdf"},"version_id":"5569c381-f764-4ee1-8b66-f4a9af6bf2eb"}]},"item_1732771732025":{"attribute_name":"旧ID","attribute_value":"51084"},"item_1732772494514":{"attribute_name":"備考","attribute_value":"The full-text file will be made open to the public on 11 Nov 2022 in accordance with publisher's 'Terms and Conditions for Self-Archiving'"},"item_title":"Study on optimal design of hatch cover via a three-stage optimization method involving material selection, size, and plate layout arrangement","item_type_id":"40003","owner":"41","path":["1730444907710"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-03-18"},"publish_date":"2023-03-18","publish_status":"0","recid":"2007897","relation_version_is_last":true,"title":["Study on optimal design of hatch cover via a three-stage optimization method involving material selection, size, and plate layout arrangement"],"weko_creator_id":"41","weko_shared_id":-1},"updated":"2025-02-21T11:10:01.915020+00:00"}
