the following questions using information obtained from the optimal solutions. (a) How much does each factory contribute to the overall profit of the company? (b) In the optimal solution for factory A, specify the unused resources (if there are any). (c) Likewise, specify any unused resources for factory B. Now let’s consider a model in which the allocation of raw material between the two factories is deter- mined by the optimal values of the decision variables. That is, we will let the model decide how to most efficiently allocate all resources within and between factories. The multiplant model is maximize 10 x 1 + 15 x 2 + 10 x 3 + 15 x 4 subject to 4 x 1 + 4 x 2 + 4 x 3 + 4 x 4 120 4 x 1 + 2 x 2 80 2 x 1 + 5 x 2 60 5 x 3 + 3 x 4 60 5 x 3 + 6 x 4 75 x 1 ,x 2 ,x 3 ,x 4 0 Create an AMPL model and data set for the multiplant optimization problem ( multiplant.mod and multiplant.dat ). Answer the following questions from information you obtain about the optimal solution. To answer questions 4i and 4j you will need to extract sensitivity information from AMPL. The class AMPL handout contains an example of how to do this. (d) What is the overall company profit? Can the company realize more profit by using the multiplant model instead of using the independent models? (e) How much does each factory contribute to profit? (f) How much raw material is allocated to each factory? (g) Specify the unused resources (if any) at each factory?

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
