Devices and incoming goods detection methods may be used. Further, the order of movement of the goods received by the belt conveyor 801 is arbitrary. For example, the articles to be received may be grouped in advance, and the articles to be received in groups may be moved by the belt conveyor 801. In addition, the worker 802 who moves the warehousing article moved to the temporary placement area 101 in advance to the temporary placement area 101 may be a robot instead of a person.

Like the equation (1) already explained, the number of articles, that is, the probability value to be integrated increases, so that the information on the integration result falls depending on the processing system. There is a fear. Therefore, Expression (4) corresponding to the logarithmic value of the second item of Expression (3) may be used for the simultaneous pick frequency evaluation. In this case, since the magnitude relationship is reversed between Formula (3) and Formula (4), it is necessary to select a storage shelf with a small evaluation value in Step 505.

  • the evaluation value of the storage shelf that decreases the frequency of simultaneous picking when the articles of all items placed in the temporary storage area 101 are stored increases. For this reason, by selecting a storage shelf having a high evaluation value as a storage destination, the operator can store the articles placed in the temporary storage area 101 in the selected storage shelf without confirming the item.

Abstract

Le système de gestion d'entrepôt selon l'invention comprend : une unité mémoire qui contient des informations de commande dans lesquelles des types, des quantités et des destinations d'expédition d'articles sont associés et des informations de stock indiquant les types d'articles en stock dans chacun d'une pluralité de casiers ; une unité de calcul de fréquence de co-occurrence, qui calcule la fréquence de co-occurrence de différents types d'articles sur la base des informations de commande ; une unité d'évaluation de fréquence de ramassage simultané, qui calcule une fréquence de ramassage simultané sur la base de la fréquence de co-occurrence et des informations de stock, la fréquence de ramassage simultané étant la fréquence avec laquelle un article à stocker, qui est un article devant être contenu dans l'un des casiers, et un article en stock différent de l'article à stocker, seraient expédiés à la même destination d'expédition dans l'hypothèse où au moins un tel article à stocker se trouvait dans le casier correspondant, et sélectionne de préférence un casier présentant une fréquence de ramassage simultané plus élevée que le casier dans lequel l'article à stocker doit être contenu ; et une unité d'instruction de stock, qui fournit une instruction pour contenir l'article à stocker dans le casier sélectionné.
