 In this paper, optimum procurement policy is worked out when trade credit is offered to the retailer by the supplier and demand is stock-dependent. The own warehouse (OW) capacity is limited and excess inventory is stored in rented warehouse (RW). The rented warehouse has modern infra-structure facility. Hence, the unit holding cost in rented warehouse is assumed to be higher than that in the...

We consider an inventory–production system consisting of a warehouse and a production facility. The warehouse is used to store products to satisfy customer demands, and its inventory is controlled by an (r,Q ) policy. Products ordered by the warehouse are processed in the production facility on a one-by-one basis, and finished products are consolidated into batches to be shipped from the produc...

We consider an optimization problem for a multiclass queueing model of a decentralized production-distribution system: A single server can produce a variety of products, and completed units pass through an infinite server delay node on their way to a warehouse inventory. Each product has its own warehouse, demand for each product is satisfied by its associated inventory, and unsatisfied demand ...

Manufacturers and wholesalers are increasingly cost conscious in response to today’s hyper-competitive environment. Lateral transshipment (LT) has been proposed as a viable solution to drive total inventory costs down whilst increasing customer service level. Our study proposes five LT decision rules with a case-based roadmap to guide professional inventory management. Results of this large fas...

This paper examines several inventory replenishment policies for a make-to-order inventory–production system that consists of a production workshop and a warehouse. Demands arrive to the production workshop according to a Poisson process, and are processed in an FCFS manner. The production workshop requires that the warehouse provides, as needed, raw materials for use in the production process....

Inventories exist throughout the supply chain in various forms for various reasons. Since carrying these inventories can cost anywhere from 20 to 40% of their value a year, managing them in a scientific manner to maintain minimal levels makes economic sense. This paper presents a near-optimal (s, Q)-type inventory policy for a production/distribution network with multiple suppliers replenishing...

Inventory control is a crucial activity for many companies. Given the recent advances in information technology, there have never been greater opportunities for coordinated inventory control across supply chain facilities. But how do we design efficient control methods and policies that take advantage of the detailed information that is now becoming available? This doctoral thesis investigates ...

The main aim of Supply Chain Management (SCM) is to produce, distribute, logistics and deliver goods and equipment in right location, right time, right amount to satisfy costumers, with minimum time and cost waste. So implementing techniques that reduce project time and cost, and improve productivity and performance is very important. Emerging technologies such as the Radio Frequency Identifica...

Gartner defines a warehouse management system (WMS) as "a software application that helps manage the operations of a warehouse or distribution center (DC)." WMS applications offer capabilities such as receiving, put­away, stock locating, inventory management, cycle counting, task interleaving, wave planning, order allocation, order picking, replenishment, packing, shipping, labor management and...
