Q:
Using the EOQ model, the higher an item's carrying costs, the more frequently it will be ordered.
Q:
Cycle counting can be used in motorcycle inventory control.
Q:
The two basic issues in inventory are how much to order and when to order.
Q:
The calculation of safety stock requires knowledge of demand and lead time variability.
Q:
Safety stock eliminates all stockouts.
Q:
It is critical that the exact quantity calculated in the EOQ model be ordered.
Q:
A quantity discount will lower the reorder point.
Q:
In the single-period model, the service level is the probability that demand will not exceed the stocking level in any period.
Q:
When the item is offered for resale, shortage costs in the single-period model can include a charge for loss of customer goodwill.
Q:
The basic EOQ model ignores the purchasing cost.
Q:
A single-period model would be used mainly by organizations going out of business.
Q:
Monitoring inventory turns over time can be used as a measure of performance.
Q:
The single-period model can be very helpful in determining how much to order.
Q:
The single-period model can be very helpful in determining when to order.
Q:
The fixed-order-interval model requires a larger amount of safety stock than the ROP model for the same risk of a stockout.
Q:
Discrete stocking levels are used when an organization does not want visibility of inventory levels.
Q:
The fixed-order-interval model requires a continuous monitoring of inventory levels.
Q:
In the fixed-order-interval model, the order size is the same for each order.
Q:
Profit margins tend to be inversely related to inventory turns.
Q:
ROP models assume that demand during lead time is composed of a series of dependent daily demands.
Q:
Solving quality problems can lead to lower inventory levels.
Q:
Variability in demand and/or lead time can be compensated for by safety stock.
Q:
Safety stock is held because we anticipate future demand.
Q:
The inventory value of the supply chain exceeds the inventory value of the organization's work-in-process inventory.
Q:
The rate of demand is an important factor in determining the ROP.
Q:
When to order can be calculated by the ROP and expressed as a quantity.
Q:
ROP models indicate to managers the time between orders.
Q:
In the quantity discount model, the optimum quantity will always be found on the lowest total cost curve.
Q:
In the quantity discount model, if holding costs are given as a percentage of unit price, a graph of the total cost curves will have the same EOQ for each curve.
Q:
Because price is not a factor in the EOQ formula, quantity discounts will not affect EOQ calculations.
Q:
The total cost curve is relatively flat near the EOQ.
Q:
Annual ordering cost is inversely related to order size.
Q:
Understocking an inventory item is a sure sign of inadequate inventory control.
Q:
Carrying cost is a function of order size; the larger the order, the higher the inventory carrying cost.
Q:
The EOQ should be regarded as an approximate quantity rather than an exact quantity. Thus, rounding the calculated value is acceptable.
Q:
The average inventory level and the number of orders per year are inversely related: As one increases, the other decreases.
Q:
The average inventory level is inversely related to order size.
Q:
EOQ inventory models are basically concerned with the timing of orders.
Q:
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.
Q:
An inventory buffer adds value and lowers cost in all supply chains.
Q:
The A-B-C approach involves classifying inventory items by unit cost, with expensive items classified as A items and low-cost items classified as C items.
Q:
Interest, insurance, and opportunity costs are all associated with holding costs.
Q:
Decoupling operations applies to the railroad industry.
Q:
An example of inventory holding cost is the cost of moving goods to temporary storage after receipt from a supplier.
Q:
Reorder point models are primarily used for dependent-demand items.
Q:
DVD recorders would be an example of independent-demand items.
Q:
In the EOQ formula, holding costs under 10 percent are expressed as percentages, above 10 percent are expressed as annual unit costs.
Q:
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.
Q:
The two main concerns of inventory control relate to the costs and the level of customer service.
Q:
The overall objective of inventory management is to achieve satisfactory levels of customer service while keeping inventory costs reasonable.
Q:

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

Q:
ERP began in manufacturing organizations but has spread into service organizations.
Q:
Load reports show capacity requirements for departments or work centers which may be more or less than the capacity available in that work center.
Q:
In MRP, EOQ models tend to be less useful for materials at the lowest levels than for upper-level assemblies of the bill of materials since higher-level assemblies have larger dollar investments.
Q:
MRP output reports are divided into two main groups, daily and weekly.
