Pre-cut timber is material for residential buildings, such as roofs, floors, and pillars, whose joints have been pre-processed. As the number of carpenters has decreased, the demand for pre-cut timber has increased. However, since the number of pre-cut timber production factories decrease, improving the productivity of those factories is an urgent issue. From this background, we are developing an algorithm for packing formation support systems to improve packing work productivity. In this paper, we propose the algorithm for packing formation of pre-cut timbers using the iterative local search with Or-opt, and discuss numerical experiments results.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Keywords<\/strong>: Pre-cut timber, Packing algorithm, Metaheuristics<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Video presentation<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-video\"><video height=\"480\" style=\"aspect-ratio: 852 \/ 480;\" width=\"852\" controls src=\"http:\/\/cirpicme.org\/wp-content\/uploads\/2021\/07\/Takashi_Tanizaki.mp4\"><\/video><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Presenting author<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table class=\"has-subtle-light-gray-background-color has-background\"><tbody><tr><td><\/td><td><\/td><td><\/td><\/tr><tr><td><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"150\" height=\"175\" class=\"wp-image-2457\" style=\"width: 150px;\" src=\"https:\/\/i0.wp.com\/cirpicme.org\/wp-content\/uploads\/2021\/07\/Takashi_Tanizaki_Photo.png?resize=150%2C175\" alt=\"\" srcset=\"https:\/\/i0.wp.com\/cirpicme.org\/wp-content\/uploads\/2021\/07\/Takashi_Tanizaki_Photo.png?w=167&amp;ssl=1 167w, https:\/\/i0.wp.com\/cirpicme.org\/wp-content\/uploads\/2021\/07\/Takashi_Tanizaki_Photo.png?resize=128%2C150&amp;ssl=1 128w\" sizes=\"auto, (max-width: 150px) 100vw, 150px\" \/><\/td><td><strong>Name:<\/strong><br><br><strong>Affiliation:<\/strong><br><br><strong>Email:<\/strong><\/td><td>Takashi Tanizaki<br><br>Kindai University, Japan<br><br>tanizaki@hiro.kindai.ac.jp<\/td><\/tr><tr><td><\/td><td><\/td><td><\/td><\/tr><\/tbody><\/table><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>by Takashi Tanizaki, Ryohei Yamashita (Japan) Abstract In recent years, many wooden houses in Japan are built using pre-cut timbers.
