Until now, many researchers have proposed portfolio models based on the stochastic approach, and there are some models considering both random and ambiguous conditions, particularly using fuzzy random or random fuzzy variables. However, the model including normal mixture distributions with fuzzy numbers has not been proposed yet. Our proposed problems are not well-defined problems due to randomness and fuzziness. Therefore, setting some criterions and introducing chance constrains, main problems are transformed into deterministic programming problems. Finally, we construct a solution method to obtain a global optimal solution of the problem.","subitem_description_language":"en"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"IEEE SMC Hiroshima Chapter"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_source_identifier":"1883-3977","subitem_source_identifier_type":"ISSN"}]},"item_1617187024783":{"attribute_name":"Page Start","attribute_value_mlt":[{"subitem_start_page":"65"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"2008-12","bibliographicIssueDateType":"Issued"},"bibliographicPageEnd":"70","bibliographicPageStart":"65","bibliographic_titles":[{"bibliographic_title":"Fourth International Workshop on Computational Intelligence & Applications Proceedings : IWCIA 2008"},{"bibliographic_title":"Fourth International Workshop on Computational Intelligence & Applications Proceedings : IWCIA 2008"}]}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2023-03-18"}],"displaytype":"simple","filename":"10-07-PS080003.pdf","filesize":[{"value":"239.7 KB"}],"mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://hiroshima.repo.nii.ac.jp/record/2000900/files/10-07-PS080003.pdf"},"version_id":"24f63141-3e98-4381-8ad9-ebc36471865c"}]},"item_1732771732025":{"attribute_name":"旧ID","attribute_value":"25622"},"item_title":"Portfolio Selection Problems with Normal Mixture Distributions Including Fuzziness","item_type_id":"40003","owner":"41","path":["1730444917621"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-03-18"},"publish_date":"2023-03-18","publish_status":"0","recid":"2000900","relation_version_is_last":true,"title":["Portfolio Selection Problems with Normal Mixture Distributions Including Fuzziness"],"weko_creator_id":"41","weko_shared_id":-1},"updated":"2025-02-18T02:58:36.647975+00:00"}
