1、供应链管理系统第三版Unit9习题与问题详解Chapter 9Planning Supply and Demand in the Supply Chain:Managing Predictable VariabilityTrue/False1. Predictable variability is change in demand that cannot be forecasted.Answer: FalseDifficulty: Easy2. Faced with predictable variability of demand, a companys goal is to respond

2、 in a manner that maximizes profitability.Answer: TrueDifficulty: Easy3. 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.Answer: TrueDifficulty: Easy4. The disadvantage of

3、 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.Answer: TrueDifficulty: Easy5. The advantage of building up inventory during the off season to keep production stable year round lies i

4、n the fact that a firm could get by with a smaller, more expensive factory.Answer: FalseDifficulty: Moderate6. The disadvantage of building up inventory during the off season to keep production stable year round is the expensive capacity that would go unused during most months when demand was lower.

5、Answer: FalseDifficulty: Easy7. 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

6、surge.Answer: TrueDifficulty: Moderate8. With supply and demand management decisions being made independently, it is easier to coordinate the supply chain, thereby increasing profit.Answer: FalseDifficulty: Moderate9. A firm can vary supply of product by controlling production capacity and inventory

7、.Answer: TrueDifficulty: Easy10. A firm that uses flexible work hours from the workforce to manage capacity to better meet demand is using a seasonal workforce.Answer: FalseDifficulty: Moderate11. Scheduling the workforce so that the available capacity better matches demand is using time flexibility

8、 from the workforce.Answer: True Difficulty: Moderate12. The use of a part-time workforce to increase the capacity flexibility by enabling the firm to have more people at work during peak periods is designing product flexibility into the production processes.Answer: FalseDifficulty: Moderate13. A fi

9、rm that uses a temporary workforce during the peak season to increase capacity to match demand is using a seasonal workforce.Answer: TrueDifficulty: Easy14. The use of dual facilities to manage capacity may be hard to sustain if the labor market is tight.Answer: FalseDifficulty: Hard15. A firm that

10、purchases peak production capability from other companies so that internal production remains level and can be done cheaply is using subcontracting.Answer: TrueDifficulty: Easy16. A firm that builds dedicated facilities to produce a relatively stable output of products over time in a very efficient

11、manner and purchases peak production capability from other companies is using subcontracting.Answer: FalseDifficulty: Hard17. A firm that has production lines whose production rate can easily be varied to match demand has designed product flexibility into the production processes.Answer: TrueDifficu

12、lty: Easy18. The use of a seasonal workforce requires that the workforce be multi-skilled and easily adapt to being moved from line to line.Answer: ModerateDifficulty: Hard19. The use of common components across multiple products, with each product having predictably variable demand, will result in

13、the demand for the components being relatively constant.Answer: TrueDifficulty: Moderate20. When most of the products a firm produces have the same peak demand season, the use of common components to create relatively constant overall demand in the components is feasible.Answer: FalseDifficulty: Mod

14、erate21. When most of the products a firm produces have the same peak demand season, it is necessary to build products during the off season that have more predictable demand.Answer: TrueDifficulty: Easy22. Operations usually makes the promotion and pricing decisions.Answer: FalseDifficulty: Easy23.

15、 Maximizing revenue is typically the objective when marketing and sales make the promotion and pricing decisions.Answer: TrueDifficulty: Easy24. Pricing decisions based only on revenue considerations often result in an increase in overall profitability.Answer: FalseDifficulty: Moderate25. The combin

16、ation of pricing and aggregate planning (both demand and supply management) can be used to maximize supply chain profitability.Answer: TrueDifficulty: Moderate26. When performing aggregate planning, the goal of all firms in the supply chain should be to maximize individual firm profits.Answer: False

17、Difficulty: Moderate27. Determining how profits will be allocated to different members of the supply chain is a key to successful collaboration.Answer: TrueDifficulty: Moderate28. In general, as the fraction of increased demand coming from forward buying grows, offering the promotion during the peak

18、 demand period becomes more attractive.Answer: FalseDifficulty: Moderate29. Offering a promotion during a peak period that has significant forward buying creates even more variable demand than before the promotion.Answer: TrueDifficulty: Easy30. Average inventory decreases if a promotion is run duri

19、ng the peak period and increases if the promotion is run during the off-peak period.Answer: FalseDifficulty: Easy31. Promoting during a peak demand month may decrease overall profitability if a significant fraction of the demand increase results from a forward buy.Answer: TrueDifficulty: Hard32. As

20、forward buying becomes a smaller fraction of the demand increase from a promotion, it is less profitable to promote during the peak period.Answer: FalseDifficulty: Hard33. As the product margin declines, promoting during the peak demand period becomes less profitable.Answer: TrueDifficulty: Easy34.

21、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.Answer: TrueDifficulty: ModerateMultiple Choice1.
