What I would like to know is what cost savings were achieved by this process. I worked in their parent company's supply chain dept. I know for a fact that the shipping data they have does not reflect true costs. It is modified internally as a warehouse management tool (Eg. if you want to drain inventory from a warehouse, you set shipping costs as zero).

There are no true dollar costs anywhere in their databases. Also, instead of evaluating all the parallel combinations, they use a branch and bound heuristics.
