I was messing with Sage for a bit and came up with this:
http://www.sagenb.org/home/pub/1973/
 
If you want to use it, just copy it and register in some sage notebook (or alternatively download & install it. Note that you also need some MLIP solver library). Then edit following variables:
 
start = {'q': 1, 'c': 100}
cost = [0, 1000, 3000, 4000]
max = [0, 1000, 1000, 300]
qual = [0, 1.1, 9, 11]
 
total=1500
target=8.3
 
start = quality & quantity before starting
cost = (don't touch the first 0) cost of the different quality products
max = (don't touch the first 0) amount available of each quality
qual = (don't touch the first 0) quality of the products
 
total = target quantity
target = target quality
 
It supports 3 different qualities by default, but adding support for more should be quite easy (tho, I'm not sure howto make a script which would allow arbitrary number of products).

Hi, it looks great. Could you elaborate more on what is this used for? Is it similar to this page that helps you determine a mixed product's price and quality?

Almost, but not quite. On that page, the first mixer attempts to find the a mixature of two products that is as close to target quality as possible without caring about the price. The second one will simply calcutate the resulting quality, price & brand.
 
My algorithm attempts to find the cheapest combination of products that will result at least target quality, but it does allow higher as well if it's cheaper (of course, that's quite unlikely. It also takes available amount in account). And it currently supports mixature of 3 products instead of only 2 (+the initial is taken in account of course). Adding more is quite easy as well.
