Abstract

Selon l'invention, le système de gestion de commande qui gère l'attente dans un établissement est pourvu d'un dispositif de réception qui reçoit d'un utilisateur un enregistrement d'attente pour l'établissement, d'une unité d'enregistrement d'informations d'attente qui enregistre des informations sur l'enregistrement d'attente acquises par l'intermédiaire du dispositif de réception comprenant la liste d'attente de l'établissement, et d'une unité de calcul de période d'attente qui calcule une période d'attente prédite qui est présentée à l'utilisateur. L'unité de calcul de période d'attente calcule une période d'attente en fonction du nombre d'enregistrements d'attente enregistrés dans la liste d'attente, et lorsqu'un temps de service prédit obtenu par ajout de la période d'attente au temps courant est compris dans une période de temps dans laquelle l'établissement est indisponible, ladite unité ajoute la longueur de la période de temps à la période d'attente pour régler la période résultante en tant que période d'attente prédite.
