The global demand for consumer electronic products has been phenomenal in the last two decades. The negative environmental effects of the growing consumption of electronic hardware are most visible in the end-of-life (EOL) stage. Remanufacturing is a viable option in electronic waste management as it reduces e waste generation and increases reuse of equipment and components. Inventory control i...

We analyze an infinite horizon, single product, periodic review model in which pricing and production/inventory decisions are made simultaneously. Demands in different periods are identically distributed random variables that are independent of each other and their distributions depend on the product price. Pricing and ordering decisions are made at the beginning of each period and all shortage...

Total spending on drugs in Canada was forecasted, by the Canadian Institute for Health Information (CIHI), to have reached $26.9 billion in 2007, an increase of 7.2% over the previous year 1 . Drug expenses were forecasted to represent 16.8% of total healthcare spending in 2007. Drug expenditure growth was lower in 2007 than the 11% increase reported in 2005 and the 9.1% increase in 2003. CIHI ...

This paper is concerned witl). "a problem in which a firm is engaged in manufacturing a number of types and sizes of goods at equal intervals, e. g. monthly, and the production is forced to fulfill the customer's demand immediately. In general the products are subject to considerable variations in demands. Let us assume that the amount demanded is uncertain but has a certain probability distrib...

Inventory control policies have been recognized as a contributory factor to the bullwhip effect and inventory instability. Previous studies have indicated that there is a trade-off between bullwhip effect and inventory performance where the bullwhip effect reduction might increase inventory instability. Therefore, there is a need for inventory control policies that can cope with supply chain dy...

This article discusses inventory management of perishable items, including the differences between inventory models that consider items’ perishability and the standard models that ignore this issue. We hope that this article will help fostering the interest of students and researchers in inventory control of perishable items, and ultimately help improving the inventory control of perishable ite...

The unanticipated shortening of a product’s life cycle can have a dramatic effect on inventory costs. Where the cause is physical decay or an unexpected decline in demand, producers can quickly find themselves quickly holding inventory that has degraded value or no value at all. In this research, we propose that an inventory system with this characteristic can be modeled as a Markov Process wit...

We consider a single-item, periodic review inventory control problem where discrete stochastic demand must be satisfied. When shortages occur, the unmet demand must be filled by some form of expediting. We allow a very general form for the cost structure of expediting, including the special case of lost sales. Examples of expediting are overtime production, where production is allowed above and...

Have advances in extrapolation methods helped to make short-range forecasts better now than in 1960? I am defining extrapolation as methods that rely solely on historical data from the series to be forecast. No other information is used. This class of methods is widely used in forecasting, especially for inventory control, process control, and in situations where other relevant data are not ava...

Non-stationary stochastic lot sizing problem appears in many industrial environments where demand is nonstationary and stochastic, and replenishments require fixed freight fees. This paper presents the cost performance assessment of three inventory control strategies proposed for the stochastic lot sizing problem, namely Hua et al. (2008)’s strategy (HYHX), Tarim and Kingsman (2006)’s model (TK...
