In multi-item inventory with very large number of items in retail sale stores, purchase dependency in demand amongst the items can be described by association rules mined from sale transaction data. With the knowledge of association rules, inventory replenishment policy can be designed which will result in low inventory cost and better profitability. The relevant inventory costs include the cos...

Members of supply chain carry inventory for different purposes. To effectively reduce the cost of inventory, information sharing mechanism is the key. The inventory can be managed in two ways in supply chain systems. The first one is the centralized inventory management system, in which, the information of inventory is highly exchanged among supply chain members. The other is the decentralized ...

In many inventory control contexts, inventory levels are only partially (i.e., not fully) observed. This may be due to non-observation of demand, spoilage, misplacement, or theft of inventory. We study a discrete-time periodic-review inventory system where the unmet demand is backordered. When inventory level is nonnegative, the inventory manager does not know the exact inventory level. Otherwi...

any organizations have wrestled with the issues of inventory locations and stocking levels. When it is critical to have inventory available for customers, the traditional approach has been to place a large amount of inventory at all locations. Carrying an excessive amount of inventory achieves a high service level, but can be enormously costly, especially if the product has a high cost per unit...

Traditionally, inventory models with trade credit policy deal with contain demand or merely dependent on the retailing price. Therefore, this paper tries to incorporate the retailer’s inventory-dependent demand and storage space limited in the retailer’s inventory model, which will make the decision-maker of inventory system to know whether to rent RW and how to order. Two easy-touse theorems a...

In this paper, we use market segmentation approach in multiproduct inventory production system with deteriorating items. The objective is to make use of optimal control theory to solve the production inventory problem and develop an optimal production policy that maximize the total profit associated with inventory and production rate in segmented market. First, we consider a single production a...

We investigate the polyhedral structure of the lot-sizing problem with inventory bounds. We consider two models, one with linear cost on inventory, the other with linear and fixed costs on inventory. For both models, we identify facet-defining inequalities that make use of the inventory bounds explicitly and give exact separation algorithms. We also describe a linear programming formulation of ...

A Norwegian version of the Penn State Worry Questionnaire (PSWQ) was administered to 304 undergraduate students together with the Beck Depression Inventory (BDI), the State-Trait Anxiety Inventory (STAI) and the Maudsley Obsessive Compulsive Inventory (MOCI). The PSWQ was also administered to a community sample comprising 879 subjects, together with the Beck Anxiety Inventory (BAI), the Beck De...
