TRUE
23) Without collaborative planning, sharing of POS data does not guarantee coordination.
TRUE
24) In most supply chains, the key to reducing the underlying forecast uncertainty is to link all forecasts throughout the supply chain to customer demand data.
TRUE
25) A reduction in replenishment lead time helps dampen the bullwhip effect by reducing the underlying uncertainty of demand.
TRUE
25) Offering a promotion during a peak period that has significant forward buying creates even more variable demand than before the promotion.
TRUE
26) Aggregation reduces the standard deviation of demand only if demand across the regions being aggregated is not perfectly positively correlated.
TRUE
27) For commodity products where price is set by the market, manufacturers can use lot size based quantity discounts to achieve coordination in the supply chain and decrease supply chain cost.
TRUE
27) Promoting during a peak demand month may decrease overall profitability if a significant fraction of the demand increase results from a forward buy.
TRUE
27) Tying allocation to past sales removes any incentive a retailer may have to inflate orders, as a result dampening the bullwhip effect.
TRUE
28) If aggregation reduces the required safety inventory for a product by a small amount, it may be best to carry the product in multiple decentralized locations to reduce response time and transportation cost.
TRUE
29) As the product margin declines, promoting during the peak demand period becomes less profitable.
TRUE
29) Cooperation and trust within the supply chain help improve performance for a variety of reasons.
TRUE
29) For products where the firm has market power, two part tariffs can be used to achieve coordination in the supply chain and maximize supply chain profits.
TRUE
3) Cycle inventory is the physical inventory in the supply chain due to either production or purchases demanded by the customer.
TRUE
3) Information is distorted as it moves within the supply chain because complete information is not shared between stages.
TRUE
3) Raising the level of safety inventory increases product availability and thus the margin captured from customer purchases.
TRUE
3) The advantage of carrying enough manufacturing capacity to meet demand in any period is very low inventory costs, because no inventory needs to be carried from period to period.
TRUE
30) Manufacturer-driven substitution increases overall profitability for the manufacturer by allowing some aggregation of demand, which reduces the inventory requirements for the same level of availability.
TRUE
30) Supply chain coordination improves if all stages of the chain take actions that are aligned and together increase total supply chain surplus.
TRUE
30) When faced with seasonal demand, a firm should use a combination of pricing (to manage demand) and production and inventory (to manage supply) to improve profitability.
TRUE
32) Periodic review policies require more safety inventory than continuous review policies for the same level of product availability.
TRUE
32) With an uncoordinated supply chain each stage tries to maximize its own profits, resulting in actions that often diminish total supply chain profits.
TRUE
33) Although a forward buy is often the retailer's appropriate response and increases their own profits, it usually increases demand variability with a resulting increase in inventory and flow times within the supply chain.
TRUE
34) Trade promotions lead to a significant increase in lot size and cycle inventory because of forward buying by the retailer.
TRUE
35) A key to the success of any supply chain is to figure out ways to decrease the level of safety inventory carried without hurting the level of product availability.
TRUE
35) The fixed ordering cost includes all costs that do not vary with the size of the order but are incurred each time an order is placed.
TRUE
36) Given the product variety and high demand uncertainty in most high-tech supply chains, a significant fraction of the inventory carried is safety inventory.
TRUE
36) Holding cost is the cost of carrying one unit in inventory for a specified period of time, usually one year.
TRUE
4) Raising the level of safety inventory increases inventory holding costs.
TRUE
4) The disadvantage of carrying enough manufacturing capacity to meet demand in any period is that much of the expensive capacity would go unused during most months when demand was lower.
TRUE
4) The inventory profile is a plot depicting the level of inventory over time.
TRUE
6) The bullwhip effect negatively impacts performance at every stage and thus hurts the relationships between different stages of the supply chain.
TRUE
7) An approach where a firm works with their retail partners in the supply chain to offer a price promotion during periods of low demand would shift some of the demand into a slow period, thereby spreading demand more evenly throughout the year and reducing the seasonal surge.
TRUE
7) As the uncertainty of supply or demand grows, the required level of safety inventories increases.
TRUE
7) Average flow time resulting from cycle inventory = Cycle Inventory/Demand = Q/2D.
TRUE
8) The bullwhip effect moves a supply chain away from the efficient frontier by increasing cost and decreasing responsiveness.
TRUE
9) A firm can vary supply of product by controlling production capacity and inventory.
TRUE
9) Increasing the lot size or cycle inventory often decreases the cost incurred by different stages of a supply chain.
TRUE
9) Lead time is the gap between when an order is placed and when it is received.
TRUE
based if the discount is based on the total quantity purchased over a given period, regardless of the number of lots purchased over that period.
TRUE
41) Average inventory A) increases if a promotion is run during the peak period. B) increases if a promotion is run during the offpeak period. C) decreases if a promotion is run during the peak period. D) decreases if a promotion is run during the offpeak period. E) both A and D
b
