Which of the following is the planned-order release using an MRP program if the gross requirement is 670 and the inventory on hand is 600? 670 600 530 70 None of the above

670 600 530 correct 70 None of the above Using net requirements, the program calculates when orders should be received to meet these requirements. This can be a simple process of just scheduling orders to arrive according to the exact net requirements or a more complicated process where requirements are combined for multiple periods. This schedule of when orders should arrive is referred to as "planned-order receipts." Since there is typically a lead time associated with each order, the next step is to find a schedule for when orders are actually released. Offsetting the "planned-order receipts" by the required lead time does this. This schedule is referred to as the "planned-order release." 670 - 600 = 70.

A company is planning for its financing needs and uses the basic fixed-order quantity inventory model. Which of the following is the total cost (TC) of the inventory given an annual demand of 10,000, setup cost of $32, a holding cost per unit per year of $4, an EOQ of 400 units, and a cost per unit of inventory of $150? A. $1,501,600 B. $1,498,200 C. $500,687 D. $499,313 E. None of the above

A. $1,501,600 Q = 400. Average Inventory = Q/2 = 200. Holding cost/year = $4. Thus, annual holding cost = $800. Annual set-up cost = 10,000/400 = 25 x $32 = 800. Demand x cost per unit = 10,000 x $150 = 1,500,000. Hence, TC = $1,500,000 + 800 + 800 = $1,501,600.

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.

False Fixed-time period models generate order quantities that vary from period to period, depending on the usage rates. The standard fixed-time period models assume that inventory is counted only at the time specified for review

Safety stock is not necessary in any fixed-time period system.

False Fixed-time period models generate order quantities that vary from period to period, depending on the usage rates. These generally require a higher level of safety stock than a fixed-order quantity system.

In inventory models, high holding costs tend to favor high inventory levels.

False Holding (or carrying) costs. This broad category includes the costs for storage facilities, handling, insurance, pilferage, breakage, obsolescence, depreciation, taxes, and the opportunity cost of capital. Obviously, high holding costs tend to favor low inventory levels and frequent replenishment.

Dependent demand inventory levels are usually managed by calculations using calculus-driven, cost-minimizing models.

False Independent demand, the need for any one item is a direct result of the need for some other item, usually a higher-level item of which it is part.

Price-break models deal with the fact that the selling price of an item generally increases as the order size increases.

False Price-break models deal with the fact that, generally, the selling price of an item varies with the order size.

In a price break model of lot sizing the lowest cost quantity is always feasible.

False Step 1. Sort the prices from lowest to highest and then, beginning with the lowest price, calculate the economic order quantity for each price level until a feasible economic order quantity is found. 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.

The "sawtooth effect," named after turn-around artist Al "chainsaw" Dunlap, is the severe reduction of inventory and service levels that occurs when a firm has gone through a hostile takeover.

Fixed-time period inventory models are "event triggered."

False The basic distinction is that fixed-order quantity models are "event triggered" and fixed-time period models are "time triggered."

The fixed-order quantity inventory model favors less expensive items because average inventory is lower.

False The fixed-order quantity model favors more expensive items because average inventory is lower.

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 optimal stocking decision in inventory management, when using marginal analysis, occurs at the point where the benefits derived from carrying the next unit are more than the costs for that unit.

False The optimal stocking level, using marginal analysis, occurs at the point where the expected benefits derived from carrying the next unit are less than the expected costs for that unit.

One of the drivers of the direct-to-store (direct distribution) approach is the decrease in trucking industry regulation.

False What accounts for the emergence of the direct-to-store model? Global sourcing and the upstream migration of value-added logistics services are certainly primary drivers.

Shortage costs are precise and easy to measure.

False When the stock of an item is depleted, an order for that item must either wait until the stock is replenished or be canceled. There is a trade-off between carrying stock to satisfy demand and the costs resulting from stockout. This balance is sometimes difficult to obtain, because it may not be possible to estimate lost profits, the effects of lost customers, or lateness penalties.

The MRP program performs its analysis from the bottom up of the product structure trees, imploding requirements level by level.

False The MRP program performs its analysis from the top of the product structure downward, calculating requirements level by level.

One of the basic purposes of inventory analysis in manufacturing and stockkeeping services is to determine the level of quality to specify.

False The basic purpose of inventory analysis in manufacturing and stockkeeping services is to specify (1) when items should be ordered and (2) how large the order should be.

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.

correct False Projected available balance is the amount of inventory (not just unsold finished goods) that is expected as of the end of a period.

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.

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.
