Since there are many debris currently around the Earth, the number of combinations of removal order becomes enormous and it is difficult to strictly obtain the optimal solution. Therefore, an efficient algorithm to optimize the trajectory of the debris removal satellite is required. The active debris removal optimization problem can be thought of as an application of the traveling salesman problem, and the application of the evolutionary algorithm can be considered. In this research, we propose a method to optimize this by using evolutionary computation, assuming a mission scenario in which a certain number of debris are selected from debris to be removed and are continuously engaged. The objective function was aimed at minimizing the total ΔV of removal satellites and maximizing the Radar Cross-Section (RCS) of eliminated debris. For optimization, we apply two evolutionary computation algorithms of NSGA-II and MOEA/D, to investigate the difference in optimization performance and to acquire knowledge on the target optimization problem.","subitem_description_type":"Other"}]},"item_4_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: カラー図版あり","subitem_description_type":"Other"}]},"item_4_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains color illustrations","subitem_description_type":"Other"}]},"item_4_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA1830034054","subitem_description_type":"Other"}]},"item_4_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-SP-18-011","subitem_description_type":"Other"}]},"item_4_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構(JAXA)"}]},"item_4_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_4_source_id_22":{"attribute_name":"ISSNONLINE","attribute_value_mlt":[{"subitem_source_identifier":"2433-2232","subitem_source_identifier_type":"ISSN"}]},"item_4_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"首都大学東京"},{"subitem_text_value":"首都大学東京"},{"subitem_text_value":"帝京大学"}]},"item_4_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Tokyo Metropolitan University"},{"subitem_text_language":"en","subitem_text_value":"Tokyo Metropolitan University"},{"subitem_text_language":"en","subitem_text_value":"Teikyo University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"山田, 祐輔"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"金崎, 雅博"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"中宮, 賢樹"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yamada, Yusuke","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kanazaki, Masahiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nakamiya, Masaki","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":"AA1830034054.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA1830034054.pdf","url":"https://jaxa.repo.nii.ac.jp/record/2858/files/AA1830034054.pdf"},"version_id":"d45a3136-fd8b-4d39-b628-35b900dc7565"}]},"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 object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"Optimization of a Trajectory to Remove Multiple Space Debris Using Evolutionary Computation","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Optimization of a Trajectory to Remove Multiple Space Debris Using Evolutionary Computation","subitem_title_language":"en"}]},"item_type_id":"4","owner":"1","path":["795","1502","1828","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-03-15"},"publish_date":"2019-03-15","publish_status":"0","recid":"2858","relation_version_is_last":true,"title":["Optimization of a Trajectory to Remove Multiple Space Debris Using Evolutionary Computation"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T09:14:55.726639+00:00"}
