multi-echelon inventory systems are one of the most important and attractive areas in modelling supply chain management so that several researches and studies have been done about. in this paper, the total cost function of a two-echelon inventory system with central warehouse and many identical retailers controlled by continuous review inventory policy is estimated. we have assumed the demand i...

the primary purpose of this paper is to highlight for the research community and practitioners the various aspects of using vmi-type supply chains in today’s business environment as well as a number of directions for future studies. in this regard, fifty articles published in major international journals, beginning in 1995, which contribute to the vmi-type supply chains are reviewed via a syste...

today, the effective inventory management plays an important role in the success of the organizations in the new business environment. it is not clearly possible for the organizations that store hundreds of inventory items to economically design an inventory management policy for each inventory item separately. moreover, various inventory items may play quite different roles in the business of ...

9/9/01 Inventory Theory Inventory Theory.S1 Inventory Models This chapter will consider several model types. Supplement 2 describes deterministic models. Even though many features of an inventory system involve uncertainty of some kind, it is common to assume much simpler deterministic models for which solutions are found using calculus. Deterministic models also provide a base on which to inco...

The relationship between inventory investment and the real interest rate has been difficult to assess empirically. Recent work has proposed a linear-quadratic inventory model with time-varying discount factor to identify the effects of real interest rate on inventory investment. The authors show that this framework does not separately identify the effects of real interest rate on inventory inve...

The paper takes the operation center of D company as an example, studies the packing material inventory control. Grouping by ABC classification, the paper establishes the joint order of multi-item inventory control model to determine the optimal order cycle, achieving the purpose of reducing inventory levels and inventory cost. Keywords-packing materials; inventory; joint order; multi-item

We consider a liquid type of a deteriorating item which is packaged by an outside supplier and is delivered to final customers by a distributor. Customers arrive according to a Poisson process and ask for an integer number of packages. Unsatisfied demands are backordered. The inventory is reviewed continuously and replenished from an external supplier with a positive deterministic lead time fol...

A standard problem in operations literature is optimal stocking of substitutable products. We consider a very general consumer-driven substitution problem with an arbitrary number of products and a quite general substitution structure, both under centralized inventory management and competition. We obtain analytically tractable solutions that generalize and extend the results of several earlier...
