The objective of inventory management is to minimize the cost of holding inventory.

The materials manager for a billiard ball maker must periodically place orders for resin, one of the raw materials used in producing billiard balls. She knows that manufacturing uses resin at a rate of 50 kilograms each day, and that it costs $.04 per day to carry a kilogram of resin in inventory. She also knows that the order costs for resin are $100 per order, and that the lead time for delivery is four days. If order size was 1,000 kilograms of resin, what would be the length of an order cycle?

An operations strategy which recognizes high carrying costs and reduces ordering costs will result in:

Even though it is often the case that no cash outflows result when demand exceeds capacity, __________ can nevertheless be experienced in those circumstances.

A car rental agency uses 96 boxes of staples a year. The boxes cost $4 each. It costs $10 to order staples, and carrying costs are $.80 per box on an annual basis. Determine: (A) the order quantity that will minimize the sum of ordering and holding boxes of staples (B) the annual cost of ordering and carrying the boxes of staples D = 96 boxes/year S = $10 H = $.80 per box-year

If average demand for an item is 20 units per day, safety stock is 50 units, and lead time is four days, the ROP will be:

The overall objective of inventory management is to achieve satisfactory levels of customer service while keeping inventory costs reasonable.

One important use of inventories in manufacturing is to decouple operations through the use of work-in-process inventories.

In the single-period model, if excess cost is double the shortage cost, the approximate stockout risk, assuming an optimum service level, is ___ percent.

Reorder point models are primarily used for dependent-demand items.

In the A-B-C approach, C items typically represent about 15 percent of the number of items, but 60 percent of the dollar usage.

DVD recorders would be an example of independent-demand items.

To provide satisfactory levels of customer service while keeping inventory costs within reasonable bounds, two fundamental decisions must be made about inventory: the timing and the size of orders.

Ann Chovies, owner of the Perfect Pasta Pizza Parlor, uses 20 pounds of pepperoni each day in preparing pizzas. Order costs for pepperoni are $10.00 per order, and carrying costs are 4 cents per pound per day. Lead time for each order is three days, and the pepperoni itself costs $3.00 per pound. If she were to order 80 pounds of pepperoni at a time, what would be the total daily costs, including the cost of the pepperoni?

Decoupling operations applies to the railroad industry.

Given the following data for a particular inventory item: $\begin{array} { l l } \text { Usage } & 500 \text { units/week } \\\text { Ordering } & \$ 40 \text { per order } \\\text { Carrying Cost } & \$ .01 \text { per unit per week } \\\text { Lead Time } & 3 \text { weeks } \\\text { Price } & \$ .50 \text { per unit }\end{array}$ For the economic order quantity, what are average weekly carrying costs?

When the item is offered for resale, shortage costs in the single-period model can include a charge for loss of customer goodwill.

A retail store that carries twice as much inventory as its competitor will provide twice the customer service level.
