본문일부/목차
12. For a telephone survey, a marketing research group
needs to contact at least 150 wives, 120 husbands, 100
single adult males, and 110 single adult females. It costs $2
to make a daytime call and (because of higher labor costs)
$5 to make an evening call. Table 52 lists the results. Because
of limited staff, at most half of all phone calls can be evening
calls. Formulate an LP to minimize the cost of completing
the survey.
27. Grummins Engine produces diesel trucks. New
government emission standards have dictated that the
average pollution emissions of all trucks produced in the
next three years cannot exceed 10 grams per truck.
Grummins produces two types of trucks. Each type 1 truck
sells for $20,000, costs $15,000 to manufacture, and emits
15 grams of pollution. Each type 2 truck sells for $17,000,
costs $14,000 to manufacture, and emits 5 grams of
pollution. Production capacity limits total truck production
during each year to at most 320 trucks. Grummins knows
that the maximum number of each truck type that can
be sold during each of the next three years is given in
Table 62.
Thus, at most, 300 type 1 trucks can be sold during
year 3. Demand may be met from previous production or
the current year’s production. It costs $2,000 to hold 1
truck (of any type) in inventory for one year. Formulate an
LP to help Grummins maximize its profit during the next
three years.
29. Juiceco manufactures two products: premium orange
juice and regular orange juice. Both products are made by
combining two types of oranges: grade 6 and grade 3. The
oranges in premium juice must have an average grade of at
least 5, those in regular juice, at least 4. During each of the
next two months Juiceco can sell up to 1,000 gallons of
premium juice and up to 2,000 gallons of regular juice.
Premium juice sells for $1.00 per gallon, while regular juice
sells for 80¢ per gallon. At the beginning of month 1, Juiceco
has 3,000 gallons of grade 6 oranges and 2,000 gallons of
grade 3 oranges. At the beginning of month 2, Juiceco may
purchase additional grade 3 oranges for 40¢ per gallon and
additional grade 6 oranges for 60¢ per gallon. Juice spoils at
the end of the month, so it makes no sense to make extra juice
during month 1 in the hopes of using it to meet month 2
demand. Oranges left at the end of month 1 may be used to
produce juice for month 2. At the end of month 1 a holding
cost of 5¢ is assessed against each gallon of leftover grade 3
oranges, and 10¢ against each gallon of leftover grade 6
oranges. In addition to the cost of the oranges, it costs 10¢ to
produce each gallon of (regular or premium) juice. Formulate
an LP that could be used to maximize the profit (revenues 
costs) earned by Juiceco during the next two months.
