QuestionAnswer
True or False? In the fixed-order interval model, the size is the same for each cycle. False. The size will vary according to demand, the only thing that is set is the time frame that the orders are made.
True or false? The fixed-order interval model requires a continuous monitoring of inventory levels. False. The fixed-order interval model requires only periodic inventory checks.
True or false? the single-period model can be very helpful in determining when to order. False. The goal of the single-period model is to identify the order quantity, or stocking level, that will minimize the long-run excess and shortage costs
True or false? In the single period model, the service level is the probability that demand will not exceed the stocking level in any period. True
True or false? The EOQ and ROP models are appropriate if unused items can be carried over and used or sold in subsequent periods. True
True or false? The two basic issues in inventory are how much to order and when to order. True
True or false? In the A-B-C approach, items with very high unit costs are always classified as "A" items. False. The A-B-C approach classifies items in order of importance, A being the most important, B moderately important and C least important.
Assumptions of the basic EOQ model Annual demand requirements are known and constant, lead time does not vary, each order is received in a single delivery
Dairy items, fresh fruit, and newspapers are items that are subject to deterioration and spoilage
In an A-B-C system, the typical percentage of the number of items in an inventory for A items is about 10%
In the A-B-C classification system, items which account for 15% of the total dollar volume for a majority of the inventory items would be classified as: C items
Generally considered reasons for holding inventory smoothing requirements on operations, decoupling internal operations, meeting anticipated demand, minimizing carrying costs
The EOQ is most relevant for: determining the fixed order quantities
The goal of basic EOQ model is to: minimize the sum of ordering and holding costs
In the basic EOQ model, if annual demand doubles, the effect on EOQ is: it increases by about 40%
In the basic EOQ model, an annual demand of 40 units, an ordering cost of $5, and a holding cost of $1/unit per year will result in an EOQ of 20
Determinants of the reorder point rate of demand, length of lead time, lead time variability, stockout risk
If no variations in demand or lead time exist, the ROP will equal: expected usage during lead time
In a single period model, if shortage and excess costs are equal, then the optimum service level is .5
In a supermarket, a vendor's restocking the shelves every Monday morning is an example of: fixed order interval
Inventory turnover cost of goods sold/average aggregate inventory value
weeks of supply (average aggregate inventory value/cost of goods sold)*52 weeks
cost of goods sold the annual cost for a company to produce the goods or services provided to customers
average aggregate inventory value the total value of all items held in inventory for the firm valued at cost
weeks of supply used when distribution inventory is dominant, a measure of how many weeks' worth of inventory is in the system at a particular point in time
bullwhip effect the variability in demand is magnified as we move from the customer to the producer in the supply chain, indicates a lack of synchronization among supply chain members
possible causes of bullwhip effect volume and transportation discounts, promotional sales, inflated orders, long cycle times, demand forecasting
demand side products and be categorized as: funtional or innovative
stable supply process the manufacturing process and the underlying technology are mature and the supply base is well established
evolving supply process the manufacturing process and the underlying technology are still under early development and are rapidly changing. the supply base may be limited in both size and experience
Hau Lee characterizes 4 types of supply chain strategies efficient, risk hedging, responsive, agile

Which of the following is implied by an annual service level of 95%?

Terms in this set (20) Which one of the following is implied by an annual service level of 95 percent? Approximately 95 percent of all demand will actually be satisfied directly from on-hand inventory.

Which of the following is not included in ordering cost?

Obsolescence factors are not included in the ordering cost of the product since they are always accounted for in the books of the business as depreciation or impairment cost.

Which of the following is the EOQ model most relevant to?

The EOQ model is most relevant for which one of the following? Determining fixed order quantities.

Which of the following is not an assumption of the basic EOQ model quizlet?

The assumptions behind the economic order quantity (EOQ) model include all of the following EXCEPT: a constant rate of demand.
