Equity is sought by minimizing the inequality in the facility-inhabitant distances, as measured by the sum of the absolute differences between all pairs of squared Euclidean distances from inhabitants to the facility. This measure meets the Pigou-Dalton condition of transfers and can easily be minimized. Efficiency is measured through optimizing the sum of squared inhabitant-facility distances, either to be minimized or maximized for an attracting or repellent facility, respectively. Geometric localization results are obtained for the whole set of Pareto-optimal solutions for each of the two resulting bicriteria problems within a convex polygonal region. A polynomial procedure is developed to obtain the full bicriteria plot, both trade-off curves, and the corresponding efficient sets.","subitem_description_type":"Abstract"}]},"item_5_identifier_34":{"attribute_name":"URI","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/2241/98654"}]},"item_5_publisher_27":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Institute for Operations Research and the Management Sciences"}]},"item_5_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1287/opre.1070.0502","subitem_relation_type_select":"DOI"}}]},"item_5_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2008 by INFORMS"}]},"item_5_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"author"}]},"item_5_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0030364X","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00327593","subitem_source_identifier_type":"NCID"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Ohsawa, Yoshiaki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ozaki, Naoya"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Plastria, Frank"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2013-12-19"}],"displaytype":"detail","filename":"OR_56-1.pdf","filesize":[{"value":"327.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"OR_56-1.pdf","url":"https://tsukuba.repo.nii.ac.jp/record/15619/files/OR_56-1.pdf"},"version_id":"d65d347f-34f3-4fe8-afc9-7f6c894772b2"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Equity-Efficiency Bicriteria Location with Squared Euclidean Distances","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Equity-Efficiency Bicriteria Location with Squared Euclidean Distances"}]},"item_type_id":"5","owner":"1","path":["501","433"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-04-23"},"publish_date":"2008-04-23","publish_status":"0","recid":"15619","relation_version_is_last":true,"title":["Equity-Efficiency Bicriteria Location with Squared Euclidean Distances"],"weko_creator_id":"1","weko_shared_id":5},"updated":"2023-12-21T08:07:34.936283+00:00"}
