In this simulation system, each component in the models of operations is changeable, and depends on some of the variables. Models are constructed using theoretical formulas of the fragment times, and flows of the work elements. The mobile-yarder, simple processor, single-grip processor, and forwarder operations are simulated. The Number of operators are 2 to 4. The simulation used a model skidding site size of 100m×60m, and the distance from the forest road is between 300m to 800m. The longer distance from the site to the forest road and from the site to the mobile yarder the profitable the systemuwith the single grip processor. The profitable number of men is three. Fora Simple processor, the profitable length of skidding road, and numbers of operators depend on the distance of the site from the forest road, and the maximum yarding-length for the mobile-yarder.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"54363","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SAKURAI, Rin"}]},{"nameIdentifiers":[{"nameIdentifier":"54364","nameIdentifierScheme":"WEKO"}],"names":[{"name":"IWAOKA, Masahiro"}]},{"nameIdentifiers":[{"nameIdentifier":"54365","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SAKAI, Hideo"}]},{"nameIdentifiers":[{"nameIdentifier":"54366","nameIdentifierScheme":"WEKO"}],"names":[{"name":"KOBAYASHI, Hiroshi"}]}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学大学院農学生命科学研究科附属演習林"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00162451","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03716007","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"610","subitem_subject_scheme":"NDC"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"The Tokyo University Forests"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学大学院農学生命科学研究科森林科学専攻"},{"subitem_text_value":"東京農工大学農学部地域生態システム学科"},{"subitem_text_value":"Department of Forest science, Graduate school of Agricultural and Life Sciences, The University of Tokyo"},{"subitem_text_value":"Department of Regional Ecosystem, Faculty of Agriculture, Tokyo University of Agriculture and Technology"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"櫻井, 倫"}],"nameIdentifiers":[{"nameIdentifier":"54359","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"岩岡, 正博"}],"nameIdentifiers":[{"nameIdentifier":"54360","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"酒井, 秀夫"}],"nameIdentifiers":[{"nameIdentifier":"54361","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小林, 洋司"}],"nameIdentifiers":[{"nameIdentifier":"54362","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":"2017-06-09"}],"displaytype":"detail","filename":"esrh102006.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"esrh102006.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/25375/files/esrh102006.pdf"},"version_id":"41e9efdd-f763-4fcd-9cb9-027fda922672"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"集材路","subitem_subject_scheme":"Other"},{"subitem_subject":"シミュレーション","subitem_subject_scheme":"Other"},{"subitem_subject":"Skidding road","subitem_subject_scheme":"Other"},{"subitem_subject":"Simulation","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"タワーヤーダ・プロセッサ・フォワーダ形集運材作業システムのシミュレーションによる検討","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"タワーヤーダ・プロセッサ・フォワーダ形集運材作業システムのシミュレーションによる検討"}]},"item_type_id":"4","owner":"1","path":["2538","2537"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-09-03"},"publish_date":"2014-09-03","publish_status":"0","recid":"25375","relation_version_is_last":true,"title":["タワーヤーダ・プロセッサ・フォワーダ形集運材作業システムのシミュレーションによる検討"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:00:53.823099+00:00"}
