Der japanische Einzelhändler Seven Eleven passt sein Ladensortiment bis zu dreimal täglich der aktuellen Nachfrage an. Er nutzt das Wissen über tägliche und wöchentliche Nachfrageschwankungen, um auf begrenzten Verkaufsflächen eine bedarfsgerechte Warenverfügbarkeit sicherzustellen. Der Convenience-Spezialist hat erfolgreich ein absatzorientiertes Warenverfügbarkeitskonzept umgesetzt
Die Logistikkosten bleiben bei erodierenden Margen das Sorgenkind des Handels. Mitunter bis zu 50 Prozent davon entfallen auf die Filialebene. Um diese Kosten zu senken, hat die Uni St. Gallen ein neues Modell entwickelt.
We investigate the value of accounting for demand seasonality in inventory control. We consider a single-location, single-item periodic-review lost sales inventory problem with cyclic demand in a retail environment. Customer demand has seasonality with a known season length, the lead time is shorter than the review period, and orders are placed as multiples of a fixed batch size. Our cost structure comprises a fixed cost per order, a fixed cost per batch and a variable cost per unit, which are used to model retail handling costs. We consider four different settings which differ in the degree of demand seasonality that is incorporated in the model: with or without within-review period variations and with or without across-review periods variations. In each case, we calculate the policy which minimizes the long-run average cost and compute the optimality gaps of the policies which ignore part or all demand seasonality. We apply the problem to a real life setting, using Point-of-Sales data. We find that it is most beneficial to incorporate demand seasonality for high-velocity products with low batch size for which demand across-review periods varies substantially.
Welche Bedeutung hat die Luftfracht als Wettbewerbsfaktor für den Wirtschaftsstandort Schweiz? Führende Schweizer Akteure aus Wirtschaft und Verwaltung haben den Lehrstuhl für Logistikmanagement der Universität St.Gallen mit der wissenschaftlichen Beantwortung dieser Frage beauftragt, um eine Grundlage für gesellschaftliche, wirtschaftliche und politische Weichenstellungen für den Luftfrachttransport zu legen.

Today's dominant shelf replenishment concepts in grocery retailing target on-shelf availability of any product at any time during store opening hours. In line, out-of-stocks are reported as the number of occasions a specific product was not available on the designated shelf space during store opening hours. In this paper, we challenge the assumption that products need to be available at any time during store opening hours. Based on point-of-sales data we show that product demand varies during a day and that these variations follow predictable patterns. Many products of different categories show low or no sales during a specific time, while sales are high during another time during store opening hours. This key finding suggests that shelf replenishment concepts for retail stores may benefit from integrating the just-in-time philosophy applied in industrial settings. We further discuss that a just-in-time shelf replenishment approach in grocery retail stores increases efficiency for high turnover products, while low turnover products are better replenished based on free capacity of store staff than specific timing. The findings have major implications for store delivery concepts, including warehouse picking
