We propose an approximation scheme for two important but difficult single-product inventory systems, specifically, the lost-sales system and the perishable product system. The approach is based on quadratic approximations of cost-to-go functions within the framework of Approximate Dynamic Programming via Linear Programming. We propose heuristics and evaluate their performance against existing h...

In linear programming tasks, the optimal solution can remain same even with a significant deviation of initial data. Thus, when studying various problems in economic and mathematical analysis, question stability often arises. The problem finding schedule for processing perishable products is solved below. For example, we could refer to sugar beet, an important strategic product that degrades du...

We study an inventory control problem of a perishable product with fixed short shelf life in Dutch retail practice. The demand is non-stationary during the week but stationary over weeks, mixed LIFO and FIFO withdrawal. supermarket uses service level requirement. A difficulty that age-distribution products stock not always known. Hence, challenge to derive practical efficient order policies dea...

In many industrial environments there is a significant class of problems for which the perishable nature of the inventory cannot be ignored in developing replenishment order plans. Food is the most salient example of a perishable inventory item. In this work, we consider the periodic-review, single-location, single-product production/inventory control problem under non-stationary stochastic dem...

because of being much perishable product as well as having low per capita consumption, much study on shrimp and its different supplying methods such as canned shrimp is needed to improve per capita consumption of seafood especially in case of shrimp. in this study, the effect of different pre-cooking methods on quality of canned penaeus semisulcatus was studied. although frying and baking metho...

in this paper, we develop an inventory model for perishable items with random lifetime in a two-echelon production-distribution system. there is a manufacturer at the first stage that produces its product with a constant rate. deterioration in this stage is modeled via a two-parameter weibull distribution. at the second stage, the retailer places the order and receives the product instantly. th...

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...

It has been a challenging task to manage perishable food supply chains because of the perishable product’s short lifetime, the possible spoilage of the product due to its deterioration nature, and the retail demand uncertainty. All of these factors can lead to a significant amount of shortage of food items and a substantial retail loss. The recent development of tracing and tracking technologie...
