Stolyar and Wang (2021) provide a proof-of-concept that randomness of lead times in inventory systems can be exploited to achieve large - potentially unlimited - performance improvements, compared to the case of constant lead time. In this paper we explore what improvements are actually...

When building datasets, one needs to invest time, money and energy to either aggregate more data or to improve their quality. The most common practice favors quantity over quality without necessarily quantifying the trade-off that emerges. In this work, we study data-driven contextual...

The new inventory policy proposed in this research is based on a dynamic order. The newly proposed policy can govern the inventory system since it selects how many items to reorder depending on the system levels. In this research the proposed policy is called a ”dynamic order” it allows the...

Inventory models with lost sales and large lead times are notoriously difficult to manage due to the curse of dimensionality. Recently, Goldberg et al. (2016) and Xin and Goldberg (2016) proved that in the lost-sales inventory model with divisible products, as the lead time grows large, a simple...

We study energy consumption and inventory control in a make-to-stock manufacturing system. We consider a Markovian system with a single server. The server consumes energy, and the associated energy cost depends on the server state: a busy server consumes more power than an idle server does, and...

In this paper we introduce and analyse, from a game theoretical perspective, several multi-agent or multi-item continuous review inventory models in which the buyers are exempted from ordering costs if the price of their orders is greater than or equal to a certain amount. For all models we...

We consider a periodic-review single-product multi-echelon inventory problem with instantaneous replenishment. In each period, the decision-maker makes ordering decisions for all echelons. Any unsatisfied demand is backordered, and any excess inventory is carried to the next period. In contrast...

We consider forecasting in base stock inventory systems with commitments concerning the expected short-term fill rate. From the managerial perspective, the short-term fill rate is an important indicator to measure the customer service level as it can be monitored on a regular basis and is the...
