In this study, we consider a perishable inventory system that has an (s, Q) ordering policy, along with finite waiting hall. The single server, which provides item to the customer after completing required service performance for item, only begins serving N customers have arrived. Impatient demand is assumed in be served lose patience and leave if server’s idle time overextends or arriving find...

This article analyzes a supply chain management system (SCM), with two echelons. We consider a perishable inventory with Poisson demand, exponential life time and positive lead time at distribution center (DC) and retailer. Partial backlogging at retailer node is assumed with limited quantity. (s, S) policy at retailer and (M-1, M) policy at DC are assumed to get a tractable analytic solution. ...

This paper deals with an inventory system with one central warehouse and a number of identical retailers. We consider perishable-on-theshelf items; that is, all items have a fixed shelf life and start to age on their arrival at the retailers. Each retailer faces Poisson demand and employs (1, T) inventory policy. Although demand not met at a retailer is lost, the unsatisfied demand at the centr...

We study a perishable inventory system under a fixed-critical number order policy. By using an appropriate transformation of the state vector, we derive several key sample-path relations. We obtain bounds on the limiting distribution of the number of outdates in a period, and we derive families of upper and lower bounds for the long-run number of outdates per unit time. Analysis of the bounds o...

In inventory, the utility of the deteriorating items decreases with time. The degree of deterioration of product utility can be treated as penalty cost in the inventory replenishment system. In this paper, we present EOQ model for those perishable products, which do not deteriorate for some period of time and after that time they continuously deteriorate with time and loose their importance. Th...

This paper is an in-depth treatment of an inventory control problem with perishable items. We focus on two prototypes of perishability for items that have a common shelflife and that arrive in batches with zero lead time: (i) sudden deaths due to disasters (e.g., spoilage because of extreme weather conditions or a malfunction of the storage place) and (ii) outdating due to expirations (e.g., me...
