A control device (10) in an article transfer facility (100): determines the size of a first dead space enclosed by a placed article (Wd) and an article (Wc) to be placed in a first candidate position (P1), a position adjacent to the placed article (Wd) on a first direction separation side (S1) and on the extreme second direction approach side (L2); if the size of the first dead space is less than a first threshold value (TH1), sets the first candidate position (P1) as the placement location for the article (Wc) to be placed; if the size of the first dead space is equal to or greater than the first threshold value (TH1), determines the size of a second dead space enclosed by the placed article (Wd) and the article (Wc) to be placed in a second candidate position (P2), a position adjacent to the placed article (Wd) on a second direction separation side (L1) and on the extreme first direction approach side (S2); and, if the size of the second dead space is less than a second threshold value (TH2), sets the secon
