Abstract
A system for fabricating a corrugated board sheet fabricated includes warp status information obtaining means (6, 6A-6H, 7, 7A, 7B, 8, 8A-8H, 240a, 240b, 241a, 241b) for obtaining warp status information concerning status of the warp of the corrugated board sheet fabricated by a corrugated-board fabrication machine (1); running-state information obtaining means (5, 5A-5H) for obtaining running state information concerning a running state of the corrugated-board fabrication machine (1); control variable calculating means (4, 4A-4H) for calculating a control variable of a particular control factor that affects the warp of the corrugated board sheet and that is one among control factors used to control the corrugated-board fabrication machine (1) based on the warp status information of the corrugated board sheet and the running state information of the corrugated-board fabrication machine (1); and control means (5, 5A-5H) for controlling the particular control factor using the control variable calculated by the control variable calculating means (4, 4A-4H).
