Proposed by Ian Miguel, Armagan Tarim

A basic distribution problem is described as follows. Given:

Find an optimal ordering policy: i.e. a decision as to how much to order at each stocking point at each time period that minimises cost.

The Wagner-Whitin form of the problem assumes that the holding costs and procurement costs are constant, and that the demands are known for the entire planning horizon. Furthermore, the stocking points have no maximum capacity and the starting inventory is 0.
