We consider a contract manufacturer who procures multiple components from independent suppliers to produce an assemble-to-order customized product for a client. The unit price of the product depends on the manufacturer’s delivery lead time. We explore how the manufacturer can use a “Vendor Managed Consignment Inventory (VMCI)” scheme to manage the underlying risk and coordinate independent supp...

this study considers a two echelon supply chain system consisting of one manufacturer and one retailer. under vendor managed inventory (vmi) program, the manufacturer is authorized to manage inventories of agreed upon stock keeping units at retail's locations. in this paper, we assume that the manufacturer monitors inventory levels at retailer's location, replenishes her stock under (...

Vendor managed inventory (VMI) is a supply-chain initiative in which the vendor is authorized to manage inventories of agreed upon stock-keeping-units at retail locations. In this paper, a modified joint inventory policy is introduced for VMI systems where the vendor takes a standard (s, S) policy and the retailers utilize can-order policies. Under the regime of a can-order policy, each retaile...

We provide a broad characterization of the supply chain settings in which perfect coordination can be achieved with a simple wholesale pricing scheme based on constant unit wholesale prices or a single quantity discount scheme. We confine ourselves to two-echelon chains with a single supplier servicing a network of retailers who compete with each other by selecting retail prices (Bertrand compe...

We consider a multi-product serial two echelon inventory system with stochastic demand. Inventories at the downstream location are replenished periodically using an automatic ordering system. Under vendor managed inventory strategies the upstream stage is allowed to adapt these orders in order to benefit from economies of scale. We propose three different VMI strategies, aiming to reduce the or...

abstractin this study, a vendor-managed inventory model is developed for a single-vendor multiple-retailer single-warehouse (sv-mr-sv) supply chain problem based on the economic order quantity in which demands are stochastic and follow a uniform probability distribution. in order to reduce holding costs and to help balanced on-hand inventory cost between the vendor and the retailers, it is assu...

Supply chain coordination has received substantial attention in the operations literature in recent years. Coordination issues in supply chains arise due to several factors, an important one being the difference in the cost impact of inventory and replenishment decisions on the manufacturer and retailer. In this paper, we address this asymmetry in cost impact that can lead to sub-optimal channe...

Vendor managed resupply is an emerging trend in logistics and refers to a situation in which a supplier manages the inventory replenishment of its customers. Vendors save on distribution cost by being able to better coordinate deliveries to different customers, and customers do not have to dedicate resources to inventory management anymore. We present and discuss the inventory routing problem. ...
