Chapter 9 Sales and Operations Planning: Planning Supply and Demand
in a Supply Chain
9.1 True/False Questions
1) Predictable variability is change in demand that cannot be forecasted.
2) Faced with predictable variability of demand, a company’s goal is to respond in a manner that
maximizes profitability.
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.
4) 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) A firm can vary supply of product by controlling production capacity and inventory.
6) A firm that uses flexible work hours from the workforce to manage capacity to better meet
demand is using a seasonal workforce.
7) Scheduling the workforce so that the available capacity better matches demand is using time
flexibility from the workforce.
8) 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.
9) A firm that uses a temporary workforce during the peak season to increase capacity to match
demand is using a seasonal workforce.
10) The use of dual facilities to manage capacity may be hard to sustain if the labor market is
tight.
11) A firm that purchases peak production capability from other companies is using
subcontracting.
12) The use of a seasonal workforce is common in the tourism industry.
13) Pricing decisions based only on revenue considerations often result in an increase in overall
profitability.
14) When performing aggregate planning, the goal of all firms in the supply chain should be to
maximize individual firm profits.
15) Determining how profits will be allocated to different members of the supply chain is a key
to successful collaboration.
16) In general, as the fraction of increased demand coming from forward buying grows, offering
the promotion during the peak demand period becomes more attractive.
17) Offering a promotion during a peak period that has significant forward buying creates even
more variable demand than before the promotion.
18) Promoting during a peak demand month may decrease overall profitability if a significant
fraction of the demand increase results from a forward buy.
19) As forward buying becomes a smaller fraction of the demand increase from a promotion, it is
less profitable to promote during the peak period.
20) 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.
