Assignment: Introduction to Optimization Instructions: 1. To solve each problem, you will need to do the following: a. Use the Generalized Optimization Modeling Procedure (GOMP) to set up your problem as follows: i . Define your model in words 1. Identify the firm's/ manager's objective function in words 2. Identify the decision variables in words 3. Identify the constraints in words ii. Formulate your model mathematically 1. Define the decision variables 2. Define the objective function in terms of decision variables 3. Define the constraints in terms of the decision variables. iii. Set up the problem in Excel and use Solver to find the optimal values of the decision variables. b. Answer the questions in each of the problems below. 2. Please submit only one Word or pdf file. Please do not submit your spreadsheet file. The file should include your GOMP that clearly specifies the notation you are using along with answers to any follow-up questions. 3. Grading Rubric: Score Description 3 Correct formulation and correct solutions 2.5 Correct formulation but incorrect solutions or Mistake(s) in formulation but correct solutions 2 Incorrect formulation and incorrect solutions 1.5 or lower Formulation implies large gap in understandingCongratulations! While cleaning out your attic, you discovered a box of vintage T-shirts of a formerly famous character/celebrity who is suddenly popular again. You'd like to sell these Tshirts in a ash online sale, but you're not sure what price to set to make the most prot. If you set the price too high, you will earn more per shirt, but may sell too few to make a good prot. On the other hand, if you set the price too low, you will sell more shirts, but may earn too little per shirt. There is a sufcient number of shirts to satisfy al demand. Your pricing speciaist has done substantial research on how online advertising affects T-shirt sales, and offers to run two types of campaigns for you: a banner ad campaign and a targeted email campaign. The specialist tells you that the number of Tshirts you will sell is given by the following formula: Quantity Sold 2 (100 A Tshirt Price + Square Root of Banner Dollars / 2 + Square Root of Email Dollars) The specialist informs you that you must set your shirt price to a minimum of $50. You must spend at least $100 on each campaign. You may spend up to $1000 dollars total on advertising (we'll call this the \"budget constraint\"). Finally, you must spend exactly as much on the banner campaign as the email campaign (we'll call this the \"balance constraint\"). a) Use the GOMP to determine your objective function, decision variables, constraints, and optimal decisions. What is your optimal price, banner advertising spend, and email advertising spend? What is your prot under the optimal solution? Don't be concerned if in your solution you sell a fractional number of T-shirts. b) Drop the balance constraint and re-solve your model. How much more prot do you earn by dropping the balance constraint? c) Add the balance consIIaint back in but drop budget constraint and resolve your model, How much more prot do you earn by dropping the budget constraint? d) Now drop the balance constraint and the budget constraint and re-solve your model. How much more prot do you earn by dropping both constraints together? e) Compare the value in d) against the sum of the values in b) and c). What does this tell you about the value of relaxing multiple binding constraints? Specically, can you predict what will happen when you drop multiple binding constraints simply by summing the effects of dropping each one individually
