inventory routing problems
Abstract: The class of Inventory-Routing Problems (IRPs) includes a variety of different optimization problems that, though often very different from each other, all consider a routing and an inventory component of an optimization problem. IRPs have received little attention, if compared to vehicle routing problems. However, as they are highly relevant in supply chain management, they are attracting an increasing number of contributions. In this seminar the class of inventory routing problems will be presented. After a review of the literature, with motivations to study this class of problems, the talk will focus on a class of discrete time IRPs that include in the objective function transportation and inventory costs. Contributions in this area will be reviewed together with their relevance in Vendor-Managed Inventory systems.
