A linear programming problem has two constraints 2X + 4Y =<100 and 1X + 8Y
=<100, plus nonnegativity constraints on X and Y. Which of the following statements
about its feasible region is true?
A) There are four corner points including (50, 0) and (0, 12.5).
B) The two corner points are (0, 0) and (50, 12.5).
C) The graphical origin (0, 0) is not in the feasible region.
D) The feasible region includes all points that satisfy one constraint, the other, or both.
E) The feasible region cannot be determined without knowing whether the problem is to
be minimized or maximized.
A maximizing linear programming problem has two constraints: 2X + 4Y < 100 and 3X
+ 10Y =< 210, in addition to constraints stating that both X and Y must be nonnegative.

A) (0, 0), (50, 0), (0, 21), and (20, 15)
B) (0, 0), (70, 0), (25, 0), and (15, 20)
C) (20, 15)
D) (0, 0), (0, 100), and (210, 0)
E) none of the above
Forward scheduling
A) begins with a delivery date, then offsets each operation one at a time, in reverse

are known
E) produces a schedule only if it meets the due date

Earl Shell owns his own Sno-Cone business and lives 30 miles from a beach resort. The
sale of Sno-Cones is highly dependent upon his location and upon the weather. At the
resort, he will profit $110 per day in fair weather, $20 per day in foul weather. At home,
he will profit $70 in fair weather, $50 in foul weather. Assume that on any particular
day, the weather service suggests a 60% chance of fair weather.
a. Construct Earl's payoff table.
b. What decision is recommended by the expected value criterion?
c. What is the EVPI?

a. What is the utilization rate for this service system?
b. What is the average time before the facility can return a breakdown to service?
c. How much of that time is spent waiting for service?
d. How many vehicles are likely to be waiting for service at any one time?
