Question

Consider the following problem.
Maximize Z = c1x1 + c2x2,
Subject to
and
x1 ≥ 0, x2 ≥ 0.
The estimates and ranges of uncertainty for the parameters are shown in the next table.
(a) Use the graphical method to solve this model when using the estimates of the parameters.
(b) Now use robust optimization to formulate a conservative version of this model. Use the graphical method to solve this model. Show the values of Z obtained in parts (a) and (b) and then calculate the percentage change in Z by replacing the original model by the robust optimization model.
