MS Office Forum / Excel / Worksheet Functions / September 2007Basic question...sorry
I'm new and trying to maximize a shipment with certain parameters. I have 6 products differing in weights (5,4,3.5,3,2,1) each with different costs (9,8,7,6,5,4) and sale price(17,13,11,9,7,5). I can only send a combination of 3 products lines with 4-8 pieces of product and cannot weigh more than 50 pounds. I am trying to maximize profit. I reviewed solver but am lost, can anyone forward me to some help? Thanks in advance! This is ,in my opinion, a "linear programming" problem. You may have to set the equations for maximising profits, simulateneously identifying the constraints ( say, in your case, the combined weight cannot be more than 50 pounds, products cannot be more than 3 and so on). For solving the equations you may use Excel. If you are not familiar with linear programming nor have any study material I suggest you refer to wikipedia.org. > I'm new and trying to maximize a shipment with certain parameters.

Since your largest weight is 5 and the package can contain a maximum of 8 pieces, any combination of eight pieces will weigh less than 50 lbs, so it really doesn't matter how you ship, given the information you've posted. You can maximize profit by shipping 8 pieces of the 1st product. That assumes, of course, that shipping costs don't vary with weight, that any 8 pieces will fit in your shipping package, and that your customers are indifferent to which products they receive. > I'm new and trying to maximize a shipment with certain parameters.

Thanks for your response, I have to order 3 different products with combination of 4-8 products with a max of 20 units? > Since your largest weight is 5 and the package can contain a maximum of > 8 pieces, any combination of eight pieces will weigh less than 50 lbs, [quoted text clipped - 14 lines] > > > > Thanks in advance!

My constraints aren't even working...This is a project for school that has been getting the best of me all day! feel free to email my contact email address and I can email my progress, or lack thereof:( > wt per pc 5 4 3.5 3 2 1 > cost per pc 9 8 7 6 5 4 [quoted text clipped - 35 lines] > > > > > > > > Thanks in advance! constraints... better post here what you have now... > I figured this out manually but cannot get into the correct formula.

These are what I have on the sheet and below is what I have in my "solver" box. Constraints: # of orders: 20 Weight(lbs) 50 # of Title/Authors: 3 Max orders per title/author 8 Min orders per title/author 4 Solver box: Cannot copy? > constraints... > better post here what you have now...
