Exercise

Logical constraint exercise

Your customer has ordered six products to be delivered over the next month. You will need to ship multiple truck loads to deliver all of the products. There is a weight limit on your trucks of 25,000 lbs. For cash flow reasons you desire to ship the most profitable combination of products that can fit on your truck.

Product Weight (lbs) Profitability ($US)
A 12,583 102,564
B 9,204 130,043
C 12,611 127,648
D 12,131 155,058
E 12,889 238,846
F 11,529 197,030

Two Python dictionaries weight, and prof, and a list prod have been created for you containing the weight, profitability, and name of each product. You can explore them in the console.

Instructions

100 XP
  • Add a constraint to ensure the total weight of the truck is less than or equal to 25,000 lbs.
  • Add a constraint so that the model will, at most, select only one of the products between D, E, and F.
