I am trying to optimize the purchase orders using Excel simplex LP solver.
The problem is when I need to decide among suppliers based on the MOQs.
If the quantity to order is large, I can choose any supplier. However, if the necessary order size is small, I must choose among suppliers who accept small batches.
I need to create a decision on the amount to order that is 0 or >= MOQ.
