Vendor Managed Inventory (VMI) policy has been widely used in various supply chains due to the benefits such as lower inventory levels and costs of retailer, and less frequent stock outs. In this study, the benefits of VMI policy in a manufacturer-retailer setting are analyzed under three different scenarios (Traditional Decision Making, VMI agreement and Centralized Decision Making). A manufacturer that produces a particular product is considered and that product is sold to a retailer operating under known demand forecasts. Under Traditional Decision Making System, each party is responsible for its own costs. Under VMI, manufacturer controls the replenishment decisions of the retailer and solves a Constrained Two-Echelon Lot Sizing Problem with Backordering. Under Centralized Decision Making, manufacturer and retailer act like merged, the problem under consideration is Two-Echelon Single Item Lot Sizing with Backordering. Through an extensive numerical study, three different scenarios’ results are compared and the conditions beneficial under VMI are identified. Under VMI, a Lagrangean Relaxation algorithm is proposed to reduce solution time. In terms of computational effort, solution times of proposed algorithm and MIP model are compared.

Inventory management through vendor managed inventory in a supply chain with stochastic demand Güneş, Hürdoğan; Savaşaneril Tüfekci, Seçil; Bayındır, Zeynep Pelin; Department of Industrial Engineering (2010) Vendor Managed Inventory (VMI) is a business practice in which vendors monitor their customers’ inventories, and decide when and how much inventory should be replenished. VMI has attracted a lot of attention due to its benefits. In this study, we analyze the benefits of VMI in a supply chain consisting of a single retailer and a single capacitated supplier under stochastic demand. We propose a VMI setting and compare the vendor managed system with the traditional system to quantify the benefits of VMI. In o...
An analysis of manufacturer benefits under vendor-managed systems Savaşaneril Tüfekci, Seçil (Informa UK Limited, 2010-01-01) Vendor-Managed Inventory (VMI) has attracted a lot of attention due to its benefits such as fewer stock-outs, higher sales, and lower inventory levels at the retailers. Vendor-Managed Availability (VMA) is an improvement that exploits the advantages beyond VMI. This article analyzes the benefits beyond information sharing and assesses the motivation for the manufacturer (vendor) behind joining such a program. It is shown that such vendor-managed systems provide increased flexibility in manufacturer's operat...
An exact solution procedure for multi-item two-echelon spare parts inventory control problem with batch ordering in the central warehouse Topan, Engin; Bayındır, Zeynep Pelin; Tan, Tarkan (Elsevier BV, 2010-09-01) We consider a multi-item two-echelon inventory system in which the central warehouse operates under a (Q, R) policy, and the local warehouses implement basestock policy. An exact solution procedure is proposed to find the inventory control policy parameters that minimize the system-wide inventory holding and fixed ordering cost subject to an aggregate mean response time constraint at each facility.
Heuristics for multi-item two-echelon spare parts inventory control subject to aggregate and individual service measures Topan, Engin; Bayındır, Zeynep Pelin; Tan, Tarkan (Elsevier BV, 2017-01-01) We consider a multi-item two-echelon spare parts inventory system in which the central warehouse operates under a (Q, R) policy and local warehouses implement (S-1,S) policy. The objective is to find the policy parameters minimizing expected system-wide inventory holding and fixed ordering subject to aggregate and individual response time constraints. Using an exact evaluation we provide a very efficient and effective heuristic, and also a tight lower bound for real-world, large-scale two-echelon spare part...
Limited quantity flexibility in a decentralized supply chain Karakaya, Selçuk; Bakal, İsmail Serdar; Department of Industrial Engineering (2010) In this study, we analyze a decentralized supply chain with a single retailer and a single manufacturer where the retailer sells two products in a single period. The products offered by the retailer consist of families of closely related products, which differ from each other in terms of a limited number of features only. The retailer places initial orders based on preliminary demand forecasts at the beginning of the period and has an opportunity to modify his initial order after receiving perfect demand in...
