Transcribed Image Text:A firm has prepared the following
binary integer program to evaluate a
number of potential locations for new
warehouses. The firm's goal is to
maximize the net present value of their
decision while not spending more than
their currently available capital.
Max 15x1 + 25x2 + 15x3+ 35x4
s.t. 8x1 + 11x2 +6x3 + 6x4 s 17
{Constraint 1}
X1 + x2 +
X1 + x2 < 1 {Constraint 3}
X1 + x3 2 1 {Constraint 4}
X2 = X4 {Constraint 5}
X4 2 2 {Constraint 2}
X3
+
S 1, if location jis selected
(0, otherwise
Solve this problem to optimality and
answer the following questions:
Xj
a. Which of the warehouse locations
will/will not be selected?
Location 1 will
Location 2 will
Location 3 will
Location 4 will
be selected
not be selected

Transcribed Image Text:b. What is the net present value of the
optimal solution? (Round your
