Determine the decision variables
Formulate the optimization model with all the constraints
• Coding in R, find the optimal number of advertisements to run in each media that maximize the expected number of exposures while satisfying all the constraints.
o What is the optimal profit value?
o What are the optimal values for the variables?
Part 2 Questions:
Using your results from Part I, formulate the total profit (as defined by Vijay).
• Use R (or any other language) to determine the optimal number of ads to run in each medium to maximize the total profit while satisfying all the constraints in Part I.
o What is the optimal profit value?
o What are the optimal values for the variables?
o Based on your calculation, what can you conclude about the accuracy of Vjay’s approximation in Part I (i.e., finding the optimal variables by using the expected number of exposures)?
Part 3 Questions:
Formulate the profit function for Vijay’s ordering problem.
• What is the decision variable?
• Determine the optimal number of gallons of Amour du jour for which Amber must order raw materials each week to maximize the restaurant’s profit. What is the optimal profit?
