If demand for an item is normally distributed we plan for demand to be twice the average demand and carry 2 standard deviations worth of safety stock inventory.

False Companies using the probability approach generally set the probability of not stocking out at 95 percent. This means we would carry about 1.64 standard deviations of safety stock.

The fixed-time period inventory system has a smaller average inventory than the fixed-order quantity system because it must also protect against stockouts during the review period when inventory is checked.

False Fixed-time period model has a larger average inventory because it must also protect against stockout during the review period, T; the fixed-order quantity model has no review period.

The standard fixed-time period model assumes that inventory is never counted but determined by EOQ measures.

By feasible, we mean that the price is in the correct corresponding range. Step 2. If the first feasible economic order quantity is for the lowest price, this quantity is best and you are finished. Otherwise, calculate the total cost for the first feasible economic order quantity (you did these from lowest to highest price) and also calculate the total cost at each price break lower than the price associated with the first feasible economic order quantity. This is the lowest order quantity at which you can take advantage of the price break. The optimal Q is the one with the lowest cost.

Fixed-order quantity systems assume a random depletion of inventory, with less than an immediate order when a reorder point is reached.

False The fixed-order quantity system focuses on order quantities and reorder points. Procedurally, each time a unit is taken out of stock, the withdrawal is logged and the amount remaining in inventory is immediately compared to the reorder point. If it has dropped to this point, an order for Q items is placed. If it has not, the system remains in an idle state until the next withdrawal.

The economic order quantity (EOQ) lot sizing technique produces or acquires exactly the amount of product that is needed each time period with none carried over into future periods.

correct False EOQ assumes that parts are used continuously during the period. The lot sizes generated by EOQ do not always cover the entire number of periods. For example, the EOQ might provide the requirements for 4.6 periods (when another EOQ would be needed).

Low level coding in MRP indicates the exact status of each item managed by the system in "real time."

correct False Low-level coding (is where) each item is placed at the lowest level at which it appears in the structure hierarchy.

In a net change MRP program, a change in one item will result in a completely new inventory plan and schedule for every item in the master production schedule.

correct False Net change systems are "activity" driven and requirements and schedules are updated whenever a transaction is processed that has an impact on the item. Net change enables the system to reflect in "real time" the exact status of each item managed by the system.

"Projected available balance" is a term referring to unsold finished goods inventory.

It: • Sets planned orders to exactly match the net requirements. • Produces exactly what is needed each week with none carried over into future periods. • Minimizes carrying cost. • Does not take into account setup costs or capacity limitations.

MRP is a logical, easily understandable approach to the problem of determining the number of parts, components, and materials needed to produce each end item.

correct True MRP is a logical, easily understandable approach to the problem of determining the number of parts, components, and materials needed to produce each end item.

MRP is based on dependent demand

correct True MRP is based on dependent demand. Dependent demand is caused by the demand for a higher-level item. Tires, wheels, and engines are dependent demand items based on the demand for automobiles, for example.

MRP provides the schedule specifying when each part and component of an end item should be ordered or produced.

correct True MRP provides the schedule specifying when each of these items should be ordered or produced.

Time fences are periods of time having some specified level of opportunity for the customer to make changes.

correct True Management defines time fences as periods of time having some specified level of opportunity for the customer to make changes.

Net change MRP systems are "activity" driven.

correct True Net change systems are "activity" driven and requirements and schedules are updated whenever a transaction is processed that has an impact on the item. Net change enables the system to reflect in "real time" the exact status of each item managed by the system.

The master production schedule states the number of items to be produced during specific time periods.

correct True The master production schedule states the number of items to be produced during specific time periods.

The deeper one looks into the product creation sequence, the more the requirements of dependent demand items tend to become more "lumpy."

correct True The requirements of dependent demand items tend to become more and more lumpy as we go farther down into the product creation sequence.

The three main inputs to an MRP system are the bill of materials, the master schedule and the inventory records file.

correct True This BOM file is one of the three main inputs to the MRP program. (The other two are the master schedule and the inventory records file.)

Computing the quantity of each component that goes into a finished product can be done by expanding (or exploding) each item in a product structure file and summing at all levels.

correct True To compute the amount of each item needed at the lower levels, each item would need to be expanded ("exploded") and summed. A more efficient procedure is to store parts data in simple single-level lists. That is, each item and component is listed showing only its parent and the number of units needed per unit of its parent.
