the inventory routing problem (irp) arises in the context of vendor-managed systems. this problem addresses jointly solving an inventory management problem and a vehicle routing problem. in this paper, we consider a multi-depot multi-vehicle inventory routing problem in which suppliers produce one type of product to be delivered to customers during a finite time horizon. we propose a two-phase ...

this paper aims to evaluate inventory cost of a two-echelon serial supply chain system under vendor managed inventory program with stochastic demand, and examine the effect of environmental factors on the cost of overall system. for this purpose, we consider a two-echelon serial supply chain with a manufacturer and a retailer. under vendor managed inventory program, the decision on inventory le...

A Vendor-Managed Inventory (VMI) supply chain is modeled using discrete-event simulation. The supply chain consists of a supplier (vendor) with a manufacturing facility and a distribution center, and a customer (retailer) with a distribution center and an outlet store. The information shared between the retailer and the vendor is subject to error and delays. The impacts of sharing erroneous dat...

In this paper we present two models for joint stock replenishment and shipment consolidation decisions which arise in the context of vendor managed inventory. Stock replenishment from suppliers or shipment to customers each incurs a lump-sum cost to the vendor. We assume the vendor uses the reorder point, lot-size policy to replenish stock and one of two schemes to dispatch shipment: the time-b...

An effective supply chain management practice improves the profitability and responsiveness of organizations. Like multinationals, small-scale enterprises are also capitalizing this feat. This paper presents a case study of a two level supply chain setting. Here a small enterprise i.e. vendor manages the inventory of the retailer. Vendor develops the forecasts and a database for replenishment d...

In this paper we present a quantity-based model for integrated inventory replenishment and shipment consolidation decisions under vendor managed inventory. Assuming the vendor uses a special reorder point, order-up-to level, or ( , ) s S policy for inventory control and adopts a quantity-based dispatching strategy under stochastic settings, we build its simulation model. By simulating in Arena ...

In this paper, we consider a two-leveled chain of supply that includes a manufacturer and a few retailers and in this chain VMI (Vendor-Managed Inventory) policy has been used. In this model, the manufacturer produces a limited amount of kind of production, and each retailer whose request is limited purchases the production with the wholesale price and sells it in retail price. In addition to t...
