Solve Problem and Applications: ch 13- prob 7 [Klein Industries manufactures three types of portable air compressors] in page 451 at the end of chapter 13 in your textbook, USA 5th edition. The data is given as part of the question. There is no external data set provided. Use what is given by the problem. You need to submit a formal APA paper to explain all your findings together with your Excel Worksheet to demonstrate you have set up the Solver correctly. In the paper, you also need to explain how you set up the LP model to solve this case study. 

13-7.  Klein Industries manufactures three types of portable air compressors: small, medium, and large, which have unit profits of $20.50, $34.00, and $42.00, respectively. The projected monthly sales are:  

                 Small   Medium  Large 

Minimum  14,000   6,200   2,600 

Maximum  21,000  12,500  4,200  

The production process consists of three primary activities: bending and forming, welding, and painting. The amount of time in minutes needed to process each product in each department is shown below: 

                                Small  Medium  Large  Available Time   Bending/forming          0.4       0.7       0.8       23,400 

Welding                       0.6       1.0       1.2       23,400 

Painting                       1.4       2.6       3.1       46,800 

How many of each type of air compressor should the company produce to maximize profit? 

a.  Formulate and solve a linear optimization model using the auxiliary variable cells method and write a short memo to the production manager explaining the sensitivity information. 

b.  Solve the model without the auxiliary variables and explain the relationship between the reduced costs and the shadow prices found in part a. 

 Solution Tip: You must use Solver tool in Excel. Set your constraints right, and fill in the solver dialogue box properly. Be sure to review links provided in the last lesson, or in one of the announcements in the first week of class. Here is a You Tube link you could view: http://www.youtube.com/watch?v=Oyc0k9kiD7o Also additional slides to explain basics and a basic example is attached. The example and slides are for demonstration and illustration purpose only to help practice how to use solver tool.
