Part 1 Project 6

[Sean Hill]

Hi, I've read through the linear programming notes, and I'm still having a bit of trouble trying to figure out this problem.

For example, for the copper, I know there needs to be some kind of restraint, but I'm not sure how to figure it out, any help please?

[Sean Hill]

I mean constraint :)

[Christopher Tensmeyer]

So you are given a certain amount of water, power, machine time, and hours of labor.  Each unit of metal (say copper), take a certain amount of each of these resources.  So the total amount of water used by the four metals needs to be less than the total amount of water used, and the same for the other resources.

This is correct. In addition, you are given a total amount of ore along with the amount of ore required to extract an ounce of each metal.

[Paul Felt]

In addition, I've clarified the verbiage of the problem slightly by removing a reference to "three processing lines" (irrelevant information).

Sorry--I realized that the previous note was misleading. Here's another try:

I've moved the reference to "3 processing lines" down to where it is relevant: where the problem uses it to calculate the total processing line time available to you (3 processing lines * 24 hours/day * 7 days/week = 504 processing line hours/week).

So we try to maximize profit per week?  If we can run three processing lines instead of one per week, would that also change the amount of power, water and labor we get per week?  (IE instead of 1000 power we get 3000 power per week in order to conform with the previous description of the spec)

Yes, you maximize profit.  Having three processing lines does not grant you more of any other resources, and it not meant to be tricky.  It merely means the amount of processing time you get is (hours in a week) * 3.
