Dissertation Abstract This dissertation focuses on the perishable inventory theory with health-care applications, the multi-variate input modeling for stochastic simulations, and temporal and bivariate dependence modeling for interarrival and service times of the queueing systems. This disser-tation contributes to the perishable inventory theory by introducing the critical level policy for the ...

Motivated by a food promotion problem, we introduce the Knapsack Problem for Perishable Items (KPPI) to address a dynamic problem of optimally filling a knapsack with items that disappear randomly. The KPPI naturally bridges the gap and elucidates the relation between the pspace-hard restless bandit problem and the np-hard knapsack problem. Our main result is a problem decomposition method resu...

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...

food labels play an important role in well being of consumers. as a part of it, date marking is a valid guide to shelf life of a food. the present study was done in 2010, in smart food center, wollongong; new south wales, australia to determine if the residents are familiar with date marking of food products. data was accumulated by either interview guide or questionnaire method. basic unselect...

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...

In this paper, we investigate retailer’s procurement policy of a perishable item that has stock-dependent demand rate. Stock-dependent demand rate implicitly implies that all items in inventory are displayed for sale. In this case, the retailer tends to display sales items such a way that FIFO policy can be enforced, while prudent customers search for freshest items, which results in LIFO polic...
