B) The problem is unbalanced and cannot be solved by the transportation method.
C) The problem will require a dummy supply with a capacity of 10 units.
D) Destinations C and D must each receive 5 units less than they require.
E) None of the above is true.

Susan has a part-time "cottage industry" producing seasonal plywood yard ornaments
for resale at local craft fairs and bazaars. She currently works 8 hours per day to
produce 16 ornaments.
a. What is her productivity?
b. She thinks that by redesigning the ornaments and switching from use
of a wood glue to a hot-glue gun she can increase her total
production to 20 ornaments per day. What is her new productivity?
c. What is her percentage increase in productivity?

Which of the following statements regarding ethical and environmentally friendly
processes is true?
A) Operations managers can be environmentally sensitive, but they must avoid
following a low cost strategy.
B) Processes can be environmentally friendly or socially responsible, but not both.
C) Operations managers can be environmentally sensitive and still follow a low cost
strategy.
D) Using energy-efficient lighting saves so little that it should not be labeled
environmentally friendly.
E) The only business strategy consistent with ethical and environmentally sensitive
management is the differentiation strategy.

The MPS calls for 120 units of Product M. There are currently 30 of Product M on
hand. Each M requires 4 of Component N. There are 20 units of N on hand.
a. Calculate the net requirements for M.
b. Calculate the gross requirements for N.
c. Calculate the net requirements for N.
Suppose an LP problem was subject to constraints of
2X+Y>= 10
X+3Y>= 20
Suppose that a new constraint is added, of the form 3X+A*Y>= 90. What is the largest
value that A can have so that this new constraint is redundant?
Every month, a distribution center will deliver 14,000 units to Retailer A at coordinates
(20, 10), 12,000 units, to Retailer B at coordinates (30, -15), and 20,000 units to
Retailer C at coordinates (4, 4). Assuming no constraints on location, at what
coordinates should the distribution center be located (rounded to two decimal places)?
A manufacturing firm is considering three potential locations for a new parts
manufacturing facility. A consulting firm has assessed three sites based on the four
factors supplied by management as critical to the location's success. Given the
management-supplied factor weights and the consultant team scores, which location
should be selected? Scores are based on 50 = best. Do the results surprise you in any
way? Comment.
In addition to labor, to which other variables have learning curves been applied?
A linear programming problem contains a restriction that reads "the quantity of X must
be at least twice as large as the quantity of Y." Formulate this as a constraint ready for
use in problem solving software.
Location A would result in annual fixed costs of $300,000 and variable costs of $55 per
unit. Annual fixed costs at Location B are $600,000 with variable costs of $32 per unit.
Sales volume is estimated to be 30,000 units per year. Which location has the lower cost
at this volume? How large is its cost advantage? At what volume are the two facilities
equal in cost?
__________ forecasts employ one or more mathematical models that rely on historical
data and/or associative variables to forecast demand.
