This article discusses inventory management of perishable items, including the differences between inventory models that consider items’ perishability and the standard models that ignore this issue. We hope that this article will help fostering the interest of students and researchers in inventory control of perishable items, and ultimately help improving the inventory control of perishable ite...

This paper studies a perishable inventory model, which assumes that each perishable item has finite lifetime, and only one item is consumed each time. The lifetimes of perishable items are independent random variables with the general distribution and so are the consumption internal. Under this assumption, by using backward equations and limit distribution of Markov skeleton processes, this pap...

This paper develops EOQ-based models with perishable items to evaluate the impact of a form postponement strategy on the retailer in a supply chain. We formulate models for a postponement system and an independent system to minimize the total average cost function per unit time for ordering and keeping n perishable end-products. An algorithm is given to derive the optimal solutions of the propo...

We consider inventory systems of “perishable” goods. Perishable goods cannot be carried from one period to another. Examples of perishable goods include newspaper, Christmas tree, and many grocery items like milk and banana. Here, a period could be one day, or one week, or any time frame that is appropriate in the application context. Suppose that a retailer sells a particular perishable produc...

now a days, management and control of perishable inventories is important in many units and industrial enterprises. basically perishable inventory management and control is more complex and challenging than inventories with unlimited lifetime. hence determining the optimal inventory policies for these products is very important.  in this paper, the optimal inventory policy for perishable items ...

In this paper we propose an approach for solving problems of optimal resource capacity allocation to a collection of stochastic dynamic competitors. In particular, we introduce the knapsack problem for perishable items, which concerns the optimal dynamic allocation of a limited knapsack to a collection of perishable or non-perishable items. We formulate the problem in the framework of Markov de...

Retailers of perishable goods are usually confronted with the inventory decision problems. The growth retail business this nature depends largely on quality decisions. In paper optimal price and trade cycle length is determined used to order quantity for each cycle. This will provide retailer guidelines make efficient decisions maximizing gains operations.

In this paper we propose a new discrete time discrete state inventory model for perishable items of a single product. Items in stock are assumed to belong to one of a finite number of quality classes that are ordered in such a way that Class 1 contains the best quality and the last class contains the pre-perishable quality. By the end of each epoch, items in each inventory class either stay in ...
