On the tab labeled "Original Problem", I have provided a problem statement and the modeling of a Linear Programming Model Problem. Carefully read the problem statement. Reference the Wyndor example from the text for an example of the integration of a linear model to Excel. The first requirement is to fill in the formulas in the GREEN cells for the Objective function and the constraints. There is no need to change the values in the RED cells. Next, open Solver and fill in the 'Set Target Cell', 'By Changing Cells', and 'Subject to the Constraints' boxes. Once you completed the Solver inputs and solved the problem, you are required to obtain the sensitivity analysis. If you do this correctly, the 'Sensitivity Report' will show up in a new tab in the bottom of the sheet. From there, proceed to the Solutions tab where you will find five questions. To answer each question, you will be required to consult the sensitivity analysis and locate the correct information from the analysis to answer each question. All answers should come from solving the model and obtaining and consulting the sensitivity data, not by resolving the model multiple times. In your response to each question, you should begin with a written sentence(s) that explains where specifically in the sensitivity analysis you found the information you need to answer each question followed by a sentence answering each respective question. Each question will be evaluated on explaining where in the sensitivity analysis you found the information necessary to answer the question (mechanical component) and for a clear, concise, grammatically correct answer to the question (written component). Questions should be answered on the Solutions tab and typed in unbolded print right after the statement of the question.

Because safety is a primary consideration at such events, many owners elect to install roll bars in their cars. Wilson Industries manufactures two types of roll bars for Chargers, Model 1 and Model 2. Model 1 requires 20 pounds of a special high alloy steel, 50 minutes of manufacturing time, and 60 minutes of assembly time. Model 2 requires 25 pounds of the special high alloy steel, 100 minutes of manufacturing time, and 50 minutes of assembly time. Wilson's steel supplier indicated that at most 40,000 pounds of the high-alloy steel will be available next quarter. In addition, Wilson estimates that 120,000 minutes of manufacturing time and 96,000 minutes of assembly time will be available next quarter. The profit contributions are $200 per unit for Model 1 and $280 per unit for Model 2. The linear programming model for this problem is as follows: Variables: Model1 = Number of Model 1 to produce Model2 = Number of Model 2 to produce Objective: Max 200 Model1 + 280 Model2 Constraints subject to: 20 Model1 + 25 Model2 < 40,000 Steel available 50 Model1 + 100 Model2
