BC Operations Problem Set
Graphical Solution
1. Solve the following linear programming model graphically. On your graph, draw and
label all constraint lines, shade the feasible space, draw a trial objective function line
labeled Z, and circle the
BC Operations Problem Set
Sensitivity Analysis
1. Consider the following linear program and
its solution:
Maximize Z= 7x1 + 7x2
Subject to:
(A) 8x1 + 6x2 48
(B) x1 + 2x2 10
x1, x2 0
x1 = 3.6
x2 = 3.2
Z = 47.6
a. If the coefficient of x1 increases,
