We consider a Poisson inventory model for perishable goods in which the items have random lifetimes and are scrapped either when reaching the end of their lifetime or a xed constant expiration age. The crucial process to describe this system is the virtual death process (W (t))t¿0, where W (t) is the residual waiting time after time t until the next ‘death’ of an item if there were no demand ar...

This paper presents an allocation model for a perishable product, distributed from a regional center to a given set of locations with random demands. We consider the combined problem of allocating the available inventory at the center while deciding how these deliveries should be performed. Two types of delivery patterns are analyzed; the first pattern assumes that all demand points receive ind...

Transshipment in retailing is a practice where one outlet ships its excess inventory to another with shortages. By balancing inventories, transshipment can reduce waste and increase fill rate at the same time. In “Separation of Perishable Inventories Offline Retailing Through Transshipment,” Li, Yu, Du explore idea transshipping perishable goods fixed finite lifetime offline grocery retailing. ...

This study dives deep into a lateral supply chain network for perishable food products and aims to determine optimal re-order order up levels multiple e-groceries within common using simulation-based optimization technique. The algorithm minimize the average inventory carried while accounting parameters like reduced wastage, improved customer satisfaction level, limited number of replenishments.

In most retail environments, when inventory runs out, the unmet demand is lost and not observed. The sales data are effectively censored by the inventory level. Factoring this censored data effect into demand estimation and inventory control decision makes the problem difficult to solve. In this paper, we focus on developing bounds and heuristics for this problem. Specifically, we consider a fi...

INTRODUCTION The importance of efficiency in the supply chain of perishable products, such as the blood products used in transfusion services, cannot be overstated. Many problems can occur, such as the outdating of products, inventory management issues, patient misidentification, and mistransfusion. The purpose of this article was to identify the benefits and barriers associated with radiofrequ...
