Assuming that I should buy 50 items from 25 different vendors with pre-known delivery duration between 2-7 day for each, which day of a week should I place each order so that the delivery days be even and balanced and even as much as possible?
What is the best way to model the simple problem below?
So a simple example is like this:
Items Vendors Delivery order day of week 1 v1 2 days ? 2 v2 3 days ? 3 v3 4 days ? 4 v4 7 days ? . . . . . . . .
