Vendor managed inventory (VMI) agreements are a supply chain collaboration principle in which the supplier is responsible for keeping at buyer between given lower and upper limits. VMI gives lot of autonomy while making replenishments, allowing to efficiently ensure availability buyer. But different suppliers may apply approaches staying limits under VMI. Relatedly, objectives not completely al...

Globalization is putting enormous pressure on the business organizations specially manufacturing one to rethink the supply chain in innovative manners. Inventory consumes major portion of total sale revenue. Effective and efficient inventory management plays a vital role for the successful functioning of any organization. Selection of inventory policy is one of the important purchasing activiti...

Members of supply chain carry inventory for different purposes. To effectively reduce the cost of inventory, information sharing mechanism is the key. The inventory can be managed in two ways in supply chain systems. The first one is the centralized inventory management system, in which, the information of inventory is highly exchanged among supply chain members. The other is the decentralized ...

This paper introduces the Inventory-Routing Problem with Transshipment (IRPT). This problem arises when vehicle routing and inventory decisions must be made simultaneously, which is typically the case in vendor-managed inventory systems. Heuristics and exact algorithms have already been proposed for the Inventory-Routing Problem (IRP), but these algorithms ignore the possibility of performing t...

The combined operation of distribution and inventory control achieved through a vendor-managed inventory strategy creates a synergetic interaction which benefits supplier and customers. Inventory-Routing Problems (IRPs) arise when inventory and routing decisions must be taken simultaneously, which yields a difficult combinatorial optimization problem. While most IRP research deals with a single...
