  7. Abstract:
  8. In today’s industrial world, firms’ focus on production only, embedded in forward supply chains is not acceptable. Environmental crises have drawn public attention to the concept of Sustainability, and government regulations are pushing firms to taking the responsibility of their wastes. These have led to manufacturers’ tendency towards collecting returns from their customers in order to use them in remanufacturing processes embedded in Reverse Supply Chains. Besides, inventory policies compatible with appropriate flows of information is widely being used, out of which is the Vendor-Managed Inventory policy. These reasons clarify the importance of research and academic work into the field of Inventory-Routing Problem with Deliveries and Pickups. Although Inventory-Routing Problem (with deliveries only) has received much attention in the past years, considering the concept of pickups has not gained much attention in modeling and solving algorithms; thus, the current research has aimed at taking a step towards filling this gap. In this regard, three versions of Inventory-Routing Problem (Inventory-routing Problem with Backhauling, Inventory-Routing Problem with Simultaneous Deliveries and Pickups, and Inventory-Routing Problem with Divisible Deliveries and Pickups) have been proposed alongside with their mathematical models. Also, a Column Generation algorithm has been proposed for for each of the first two problems (Inventory-routing Problem with Backhauling, and Inventory-Routing Problem with Simultaneous Deliveries and Pickups). We hope we have been able to take even a mere step towards developing Branch-and-Price, and Branch and-Price-and-Cut algorithms in the field of Inventory-Routing Problems with Deliveries and Pickups
