Correct predictions are in blue. If we detect only a subset of a labelled sentence, we highlight the caught part as blue, the missing part light blue. False positives are in green and false negatives are in red.

Problem 040 (Distribution problem with Wagner-Within costs) — Constraint detection

Inventory theory provides methods for managing and controlling inventories under different policy constraints and environmental situations . A basic distribution system consists of a supply chain of stocking points arranged in levels . Customer demands occur at the first level , and each level has its stock replenished from the one above . Typically , a holding cost per unit of inventory is associated with each stocking point , under the assumption that a parent stocking point has a lower holding cost than any of its children . A procurement cost per order is also associated with each stocking point . Given customer demands for each stocking point in the first level over some planning horizon of a number of periods , the problem is then to find an optimal policy : a set of decisions as to when and how much to order for each stocking point , such that cost is minimised . 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 .
