A Hidden Markov Model for an Inventory System with Perishable Items
نویسندگان
چکیده
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 optimal replenishment schedule is formulated as an optimal stochastic control problem.

Limit Distribution of Inventory Level of Perishable Inventory Model
This paper studies a perishable inventory model, which assumes that each perishable item has finite lifetime, and only one item is consumed each time. The lifetimes of perishable items are independent random variables with the general distribution and so are the consumption internal. Under this assumption, by using backward equations and limit distribution of Markov skeleton processes, this pap...
متن کامل(1, T) policy for a Two-echelon Inventory System with Perishable-on-the-Shelf Items
This paper deals with an i * Corresponding author Email address: nventory system with one central warehouse and a number of identical retailers. We consider perishable-on-the-shelf 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 retai...
متن کاملFiltering and Predicting the Cost of Hidden Perished Items in an Inventory Model
This paper is concerned with a discrete time, discrete state inventory model for items of changing quality. Items are assumed to be in one of a finite number, , Q of quality classes that are ordered in such a way that Class 1 contains the best quality and the last class contains the pre-perishable quality. The changes of items' quality are dependent on the state of the ambient environment. Furt...
متن کاملPerishable Inventory Model with Retrial Demands, Negative Customers and Multiple Working Vacations
This paper presents the analysis of a continuous review perishable inventory system wherein the life time of each item follows an exponential distribution. The operating policy is (s,S) policy where the ordered items are received after a random time which follows exponential distribution. Primary arrival follows Poisson distribution and they may turnout to be posit...
متن کاملDesigning an integrated production/distribution and inventory planning model of fixed-life perishable products
This paper aims to investigate the integrated production/distribution and inventory planning for perishable products with fixed life time in the constant condition of storage throughout a two-echelon supply chain by integrating producers and distributors. This problem arises from real environment in which multi-plant with multi-function lines produce multi-perishable products with fixed life ti...
