In order to shorten this delivery lead time, it is desirable to store the inventory of products generated by prospective production closer to the customer than the manufacturing base. For example, a distribution warehouse is used as a temporary storage area. A logistics network including manufacturing to delivery is called a supply chain. Taking various measures to reduce manufacturing lead time and delivery lead time is called Supply Chain Management. In supply chain management, where manufacturing bases and warehouse bases are located, and how quickly products are shipped from each base, is important for the competitiveness of companies.

For example, it is designed to automatically replenish products to a stock shelf to be collected, and the collection work is performed manually.

Abstract

Bien qu'un entrepôt de distribution (2) ait un haut rendement d'utilisation de l'espace avec des étagères de collecte d'articles installées dans une direction parallèle ou perpendiculaire à une droite reliant des piliers dans une zone rectangulaire de l'entrepôt de manière à augmenter le rendement d'utilisation de l'espace, il existe une limite sur la mesure dans laquelle la vitesse de collecte d'articles peut être augmentée. L'invention concerne un dispositif de génération d'agencement d'entrepôt (1) pourvu : d'une unité d'analyse de fréquence d'expédition (11) qui analyse une fréquence d'expédition d'un article de marchandise à livrer (53) sur la base de données d'instruction d'expédition d'entrepôt qui sont des données d'instruction pour l'expédition de l'article de marchandise à livrer (53) à partir de l'entrepôt de distribution (2) ; et d'une unité de génération d'agencement d'étagères de collecte d'articles (134) qui délivre en sortie des données d'agencement d'entrepôt qui sont des informations d'agencement concernant une rangée d'étagères de collecte d'articles servant à stocker temporairement les articles de marchandises à livrer (53) dans une zone de l'entrepôt de distribution (2), sur la base de la fréquence d'expédition de chaque article de marchandise à livrer (53), de données de conception d'entrepôt (133) et d'un paramètre de conception d'agencement (132). Le dispositif de génération d'agencement d'entrepôt (1), par génération d'un agencement d'étagères de collecte d'articles sur la base des données d'instruction d'expédition, fournit les données d'agencement d'entrepôt (134) avec une meilleure productivité de collecte d'articles.
