In equipment-intensive industries such as truck manufacturing, electronics manufacturing, photo copiers,and airliners, service parts are often slow moving items for which, in some cases, the transshipment timeis not negligible. However, this aspect is hardly considered in the existing spare...

In distribution systems, excess stocks can be shared across different locations to fulfill unsatisfied demand. This raises many operations problems including inventory policies, transportation, partner selection and contracts. This paper reviews the up-to-date literature in inventory...

The stowage decision determines how arriving products are distributed in a storage system or warehouse. In particular we consider the zone-stowage decision for large warehouses that are organized into distinct storage zones. An example would be a multi-floor warehouse where each floor is a...

We consider a multi-product newsvendor under the law-invariant coherent risk measures. We first establish a few fundamental properties of the model regarding the convexity of the problem, the symmetry of the solution and the impact of risk aversion. Specifically, we show that for identical...

We propose the first learning algorithm for single-product, periodic-review, backlogging inventory systems with random production capacity. Different than the existing literature on this class of problems, we assume that the firm has neither prior information about the demand distribution nor...

Vendor Managed Inventory (VMI) contracts are anchored on a fill rate at which the vendor is expected to meet the end-customer demands. Violations of this contracted fill rate due to excess and insufficient inventory are both penalized, often in a linear, but asymmetric manner. To minimize these...

We revisit the computational framework based on the M-estimation principle in the context of inventory forecasting in periodic review order-up-to inventory systems calibrated with a beta service level constraint. In particular, we discuss the identification condition for the estimation of base...

The first half of the paper is devoted to description and implementation of statistical tests arguing for the presence of a Brownian component in the inventories and wealth processes of individual traders. We use intra-day data from the Toronto Stock Exchange to provide empirical evidence of...
