23) The Alphabet Soup Company is delivering the monthly supply of their fine product to their seven
customers. The distances in miles between the customers are shown in the table and, wishing to be as
efficient as possible, the driver would like to find the shortest route that takes her from the starting point
A to every customer and then back to the starting point. Use the nearest neighbor heuristic to identify a
route that would minimize the distance traveled.

24) Sweet Action, Inc. is making the daily cupcake run across the Oklahoma City metropolitan area. They
have seven customers and have identified the driving distance (in miles) between each pairwise
combination as shown in the table. One-way streets and various construction projects affect driving
distances such that the distance from one to the other may not be the same depending on which site is the
starting point. Identify the most energy efficient route that begins at Sweet Action headquarters (SA) and
visits each customer once before returning to headquarters.

25) Copies of the Wall Street Journal are printed locally and delivered to ten different newsstands
throughout the area. The spotter picks up the papers at 4 a.m. and visits each site once, drops off a
predetermined number of copies, and proceeds to the next location before returning to the printer. The
driver has always determined his route “pretty much at random” however he recently read an article (in
the Wall Street Journal) that addressed sustainability issues in services. He was so taken with the
sustainability concept that he has decided to determine an optimal route for his ten stops. One morning
he picks up his papers at 4 a.m. and then jots down each possible route and adds up the total distance
traveled for that route. If it takes him one minute to evaluate a route, at what time will he begin to make
his deliveries?
26) A New Holland supplier ships flywheels to the assembly plant for the model 68 Hayliner string baler.
Each flywheel weighs 80 pounds and 10 of them fit on a standard pallet. A complete pallet ships as
freight class specification 85. Use the matrix of weight breaks and freight class (below) to calculate the
shipping cost for a demand of 15 pallets and also determine the shipping cost per flywheel.
27) A HD TV manufacturer produces sets at the rate of 72 units per week. The TV sets weigh 23 pounds
each and two dozen fit on a pallet. If the shipping class is to be 70, what’s the break-even point for a more
favorable shipping rate and what does it cost to send a week’s supply of TVs?

15.4 Disaster Relief Supply Chains
1) In a disaster relief supply chain, preparation should precede the disaster, which in turn precedes the
response.
2) In the recovery phase of disaster relief, supplies can be ordered with more normal lead times since
demand can be estimated more accurately.
3) In major international disasters, the United States typically has the leadership role.
4) Which of these sequences in humanitarian supply chain operations is correct?
A) Preparation before Response
B) Response before Preparation
C) Disaster after Response
D) Recovery before Response
5) First aid kits are packed and staged at distribution hubs in the:
A) Recovery operation.
B) Preparation operation.
C) Response operation.
D) Forecast operation.
6) Which of these statements about disaster relief supply chains is best?
A) Critical supplies are usually deployed the instant they are available in the disaster zone.
B) Employee turnover in disaster relief is low since these individuals are dedicated to the cause.
C) Most disaster relief supply chains exist for only short times.
D) Supplies follow a pull flow initially but change to a push flow once demand is more predictable.
7) ________ can sometimes provide enough lead time to assemble disaster relief resources, but often
disasters happen with little to no warning.
8) The three major disaster relief chain operations are ________, ________, and ________.
9) The life cycle of a disaster relief supply chain begins with the ________ step.
10) In some disaster relief efforts ________ is a problem because stocks of some supplies are excessive and
for other supplies, stocks are non-existent.
23
11) What are the primary disaster relief supply chain management challenges?
Answer: Answers will vary, but the challenges presented in the text include:
Design implications. Many disaster relief supply chains exist for only short times. At the onset of a disaster,
the supply chain could require a new design from scratch featuring quick response capabilities involving
innovative suppliers. Response operations are all about speed and agility in the supply of needed items.
Risk-taking is encouraged because the priority is quick access. Recovery operations, however, require a
more scheduled program, favoring an efficient supply chain design.
Command and control. In major international disasters, the United Nations typically has the leadership
15.5 Supply Chain Ethics
1) The standard governing nine dimensions of ethical workforce management is ISO 8000:2008.
2) The standard for time off as established by Social Accountability International is at least one day off for
every five-day period.
3) A just-in-time (JIT) system minimizes inventory cost for the company but increases inconvenience in
the form of noise, traffic, and air pollution for the community at large.
4) Suppliers have an ethical responsibility to label products accurately.
5) Which of these statements is in accordance with the ethical standards on workplace management?
A) Workers should typically be 15 years of age or older.
B) Require no more than 80 hours per work week.
C) Use no corporal punishment, only verbal abuse.

D) gratuities and perks.
7) According to SA8000:2008 working hours should be limited to no more than ________ hours per week.
8) What are the three most important ethical considerations for workforce management?
Answer: Answers will vary, most likely according to how the respondent has been mistreated in his
career. The ethical considerations offered in the text are as follows:
Child Labor: Employ no underage workers, usually taken to be under 15 years of age.
Forced Labor: Prohibit the use of forced labor, including prison or debt bondage labor.
