To have an efficient control of a huge amount of inventory items, traditional approach is to classify the inventory into different groups. Different inventory control policies can then applied to different groups. The well-known ABC classification is simple-to-understand and easy-to-use. However, ABC analysis is based on only single measurement such as annual dollar usage. It has been recognize...

The paper provides a new approach to study the problem of optimal control of two-item inventory model with deteriorating items. The total cost includes the sum of the holding costs of inventory, the holding costs of one item due to the presence of other and the production costs. The solution of optimal control problem of two-item model will be carried out using Pontrygin principle. The controll...

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 deals with the problem of determining the optimal retailer’s replenishment decisions for deteriorating items under two levels of trade credit policy within the economic order quantity (EOQ) framework to reflect the supply chain management situation. We investigate the retailer's inventory system as a cost minimization problem to determine the retailer's optimal inventory policy under...

Disruption management has recently become an active area of research. In this study, an extension is made to consider the fact that some products may deteriorate during storage. A productioninventory model for deteriorating items with production disruptions is developed. Then the optimal production and inventory plans are provided, so that the manufacturer can reduce the loss caused by disrupti...

In his paper a deterministic two warehouse Electronic component inventory model for deteriorating items, timedependent demand, variable holding cost and vector evaluated genetic algorithm has been developed under assumption that the Electronic component inventory cost including time-dependent demand, holding cost, vector evaluated genetic algorithm and deterioration cost in Rented Warehouse is ...

We suggest a new inventory continuous time stochastic model for deteriorating items. We derive optimal operating characteristics of the expected cost per unit time under the assumption that demand in each replenishment cycle forms a regenerative process. We also present numerical examples. 2000 Mathematics Subject Classification. Primary 60K30, 60J10, 90B05.
