ABSTRACT In this paper, we develop a supply network model for a service facility system with perishable inventory (on hand) by considering a two dimensional stochastic process of the form (L, X) =   0 )); ( ), ( (  t t X t L , where L (t) is the level of the on hand inventory and X (t) is the number of customers at time t. The inter-arrival time to the service station is assumed to be expone...

My dissertation addresses a number of challenges in perishable inventory management in supply chains, providing both theoretical results and managerial insights. Essay 1: In this essay, we review the literature on supply chain management of perishable products that have a fixed or random lifetime, primarily focusing on challenges introduced by aging of such products. We start with a review of t...

We study the global optimal solution for a planning problem of inventory control of perishable products and non-stationary demand.

We address the problem of determining optimal ordering and pricing policies in a finite-horizon newsvendor model with unobservable lost sales. The demand distribution is price-dependent and involves unknown parameters. We consider both the cases of perishable and non-perishable inventory. A very general class of demand functions is studied in this paper. We derive the optimal ordering and prici...

In this paper, we deal with the problem of a fixed number of units of a certain perishable commodity over a continuous time horizon. Airline seats, hotel rooms, advertising space in newspapers, and some seasonal products that must be sold before the end of the season are examples of such commodities that cannot be carried over and are not storable for consumers. This paper considers such a prob...

– This paper derives a good approach to approximating the expected inventory level per unit time for the continuous review perishable inventory system. Three existing approximation approaches are examined and compared with the proposed approach. Three stockout cases, including the full backorder, the partial backorder, and the full lost sales cases, which customers or material users generally u...
