Right. Initially you're trying to optimize the path for X people. So to get X items which are distributed in a given way, you're trying to have each person take the shortest path possible. However, based on orders, you want to optimize the distribution of items in the warehouse to further shorten the paths. Granted, that distribution could be biased wildly based on all sorts of factors (i.e. seasonal activity). Fun problem to say the least. :)
