Summary: Emerging advanced technologies allow logistics service providers to offer supply chain services beyond just shipping, such as inventory management. This study investigates a preventive transshipment system led by a logistics service provider, where the provider serves as the decision-maker and provides optimal ordering and transshipment policies for online retailers. The results demonstrate that implementing this system can significantly increase the total profit for both the retailer and the logistics service provider.

Summary: This research investigates the issue of transshipment for cross-filling and imputation for missing demand data. It establishes a novel integrated problem that combines demand-data imputation processes and transshipment decisions. The study develops suitable imputation strategies and new algorithms for transshipment to handle missing demand data. The analysis reveals that conventional imputation methods result in inferior transshipment decisions and that imputed values should be adjusted for effective transshipment. This study demonstrates how inventory transshipment can be successfully carried out with appropriate treatment of missing demand data in practice.

Summary: This paper addressed a two-level supply chain with a multi-product, multi-vehicle inventory sharing routing problem, and proposed a two-phase matheuristic to solve it. The study showed the significant benefits of inventory sharing on the overall supply chain.

Summary: Small businesses with multiple stocking locations face challenges of high ordering costs and imbalanced inventories. To address these challenges, an inventory system of multiple retailers is considered, where they order together periodically and transship available inventory between retailers. Analytical approaches are provided to evaluate costs and determine optimal order interval, order-up-to level, and timing of transshipment. The findings highlight the optimal order interval, timing of transshipments, and the effectiveness of transshipment in reducing costs.

Summary: This paper studies three classes of allocation policies and unifies the analysis of these policies through the concept of persistency values. It is found that the performance gaps between optimal anticipative policies and adaptive policies are bounded in certain models, while the gaps between optimal adaptive policies and responsive policies can be arbitrarily large. The techniques and persistency values obtained from optimal responsive policies can be used to design good adaptive and anticipative policies for other resource allocation problems, providing a unified approach to algorithm design and analysis for these problems.

Summary: This study finds that the two-stage policy outperforms other capacity allocation policies in the presence of supply disruption. Partial disruption is more manageable compared to full disruption. Additionally, in cases with fixed penalty rates, suppliers are better off negotiating longer performance review periods.

Summary: This study investigates the value of inventory integration for a company selling seasonal products over two periods, showing that operational value is always positive while behavioral value can be positive or negative, influenced by factors such as demand variability, market correlation, and salvage value-to-cost ratio. Other factors, such as endogenous pricing, asymmetric market demands, and consumer visit costs, also play a role in determining the value of integration.

Summary: This article investigates the transshipment decisions of competing retailers in overlapping markets. The study finds that the optimal transshipment policy consists of no-transshipment, partial-transshipment, and full-transshipment, which are determined by the interplay of switching probability, transshipment price, and remaining inventory. Transshipment dampens or intensifies inventory competition depending on the transshipment price. Bilateral transshipment can lead to Pareto improvement for competing retailers, even when the competition effect is negative. The article also provides explicit conditions and formulas to compute the coordinating transshipment prices.

Summary: The study demonstrates that a hybrid transshipment policy can increase retailer profits, as well as the existence of reactive and preventive transshipment policies. Retailers are more likely to adjust inventory through ordering when transshipment prices are low, and through hybrid transshipment when transshipment prices are high.

Summary: Retail networks utilize on-demand inventory transshipments to avoid lost sales and establish interconnected networks, estimating product availability under uncertain demand and customer substitution. The proposed model considers both in-stock and network availability, balancing transshipment costs and customer satisfaction.

Summary: The LNG-ADP problem is a tactical planning problem for creating an annual delivery program for a LNG producer. This study proposes a discrete-time formulation for the problem, which allows for transshipment, intermediate storage, and waiting at unloading ports. The impact of different heuristic configurations on run time and solution quality is investigated, and it is found that a shorter central period provides the best objective function while a longer central period improves run time. Allowing waiting can reduce run time, but may not necessarily improve the objective function value.

Summary: This paper explores the idea of transshipping perishable goods in offline grocery retailing, showing that transshipment can play a dual role of inventory balancing and inventory separation. By separating inventories, retailers can sell older items more easily and reduce waste as a result. The optimal inventory separation policy is characterized by two increasing switching curves dividing the state space into three regions, and numerical studies are conducted to quantify the value of transshipment.
