What project selection should your company choose? (You decide what criterion to use, but recall that this Business school.)
Please show/explain using excel solver
Answer: Projects Chosen: 3,4,5,6,7,8,12,13,14,15
Profit : 43000
Step 1: Decision Variables of the Problem are as follows-
Here, we have 15 decision Variables i.e Projects chosen. Let's say Projects to be X1, X2,.......X15
Step 2: Objective Function: Maximize Profit by the selection of the projects.
1500*X1+2000*X2+2500*X3+7000*X4+4000*X5+3000*X6+4500*X7+3500*X8+1500*X9+2000*X10+2500*X11+7000*X12+4000*X13+3000*X14+4500*X15
Step 3: Constraints:
for 2016:
1) 400*X1+500*X2+200*X3+300*X4+450*X5+650*X6+350*X7+300*X8+500*X9+600*X10+150*X11+250*X12+220*X13+170*X14+420*X15 <= 3500
2) for 2017
230*X1+270*X2+430*X3+220*X4+500*X5+450*X6+530*X7+700*X8+800*X9+250*X10+500*X11+340*X12+400*X13+300*X14+400*X15<= 4500
3) for 2018
330*X1260*X2+430*X3+270*X4+400*X5+320*X6+330*X7+260*X8+430*X9+270*X10+400*X11+320*X12+250*X13+300*X14+260*X15<=4000
4) for 2019
400*X1+500*X2+200*X3+300*X4+450*X5+650*X6+350*X7+300*X8+500*X9+600*X10+150*X11+250*X12+220*X13+170*X14+420*X15 <=3450
5) for 2020
230*X1+270*X2+430*X3+220*X4+500*X5+450*X6+530*X7+700*X8+800*X9+250*X10+500*X11+340*X12+270*X13+300*X14+400*X15 <=4500
6)Xi = binary, i=1,2,3,.......15
Below, I have attached the solved excel worksheet in the solver
The decision should be made in order to maximize the profit by the undertaken projects and funds needed by the chosen projects need to be within funds available to the company.
Thank You!
