Due to the rapid development of technology in recent years, market competition and customer expectations have increased more than ever. In this situation, it is vital for businesses survival to determine the appropriate policy for inventory control, pricing, and routing, and decisions regarding each of them are often made separately. If the products have a perishable nature, it will be more imp...

With the intensification of global warming and the levy of energy tax, more industries are paying attention to energy saving and reduction of carbon footprint. For the food industry, energy cost in the supply chain of perishable food is quite high because of cold-chain transport and storage. Therefore, the efficacies of cold chain management and inventory control are the key factors that increa...

This paper deals with a parametric multi-period integer-valued inventory model for perishable items. Each item in the stock perishes in a given period of time with some probability. Demands are assumed to be random. and the probability that an item perishes is not known with certainty. Expressions for various parameter estimates of the model are established and the. problem of finding an optima...

The federal government maintains large quantities of medical supplies in stock as part of its Strategic National Stockpile (SNS) to protect the American public in case of a public health emergency. Managing these large perishable inventories effectively can help reduce the cost of the SNS and improves national security. In this work, we propose a modified Economic Manufacturing Quantity (EMQ) m...

In this article, we consider a two commodity continuous review perishable inventory system with a finite number of homogeneous sources of demands. The maximum storage capacity of i S units for the th i commodity 1,2) = (i . The life time of items of each commodity is assumed to be exponentially distributed with parameter i  1,2) = (i . The time points of primary demand occurrences form indepen...

In this paper, we present an inventory model for perishable items with freshness-dependent demand rate and partial backlogging. Because the customers prefer to purchasing fresh items for given price, the demand rate is assumed to be decreasing in the age of the items. The existence and uniqueness of the optimal solution of the profit per unit time are examined although the profit function is no...
