I want to progressively calculate a discount based on the amount of product sold. Are there any models which allow to take into account different type of products and can calculate the discounts based on the target profit? I am using logistic growth function at the moment, but maybe there is better solution lurking around? Where should I look.
I know R and Python and some math, but don't know much about economics. So if anyone can point me to the right direction it would be great.
