<p>When a consumable is assessed to be gradually consumed (S102: YES), an operation device (1) assesses whether 50% or less of the consumable remains (S103). If 50% or less remains in S103 (S103: YES), and a fixed value ordering mode applies (S104: NO), the operation device (1) executes an ordering process in which ordering information with which the consumable is ordered is transmitted (S114). If 50% or less remains in S103 (S103: NO), a consumable forecast mode applies (S104: YES), and a forecast period for the remaining quantity to reach zero is assessed to be 10 days or less, the operation device (1) executes an ordering process (S114).</p> |
