PHASE I Reading over Phase 1, I decided that a new variable, Domestic Salary, needed to be added to the LINGO code in order for us to be able to solve task 3. This gave us the code that will be used for Phase 1: max = 120000*P - 120*P*P-(((150+DS)*Q1+.1*Q1*Q1+150*D_TRAIN+300*D_TRUCK)+ ((145+DS)*Q2+.08*Q2*Q2+275*S_TRAIN+550*S_TRUCK)+(720*Q3+.05*Q3*Q3)); 200=DS; D_TRAIN+D_TRUCK=Q1; S_TRAIN+S_TRUCK=Q2; S_TRAIN<=1200; D_TRAIN<=800; Q1+Q2+Q3=D; 120000-120*P=D; Q1>=0; Q2>=0; Q3>=0; S_TRAIN>=0; D_TRAIN>=0; S_TRUCK>=0; S_TRAIN>=0; P>=0; 44*S_TRUCK+24*D_TRUCK+110*S_TRAIN+150*D_TRAIN+800*Q3=CF; CF<=1892267; As the Domestic Manager and phase leader I took the first opportunity I saw to raise domestic production and came to the conclusion that a 35% increase would be a good goal to enforce. This led to over \$100,000 loss in profit, a smaller carbon footprint, and a slight decrease in production at our off-shore plant.

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.
