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 112 (Lot Sizing Problem) — Constraint detection

The Discrete Lot Sizing problem considered here is a multi-item , single machine problem with capacity of production limited to one per period . There are storage costs and sequence-dependent changeover costs , respecting the triangle inequality . Each order consisting of one unit of a particular item has a due date and must be produced at latest by its due date . The stocking -LRB- inventory -RRB- cost of an order is proportional to the number of periods between the due date and the production period . The changeover cost $ q _ -LCB- i , j -RCB- $ is induced when passing from the production of item i to another one j with $ q _ -LCB- i , j -RCB- = 0 \ forall i $ . Backlogging is not allowed . The objective is to assign a production period for each order respecting its due date and respecting the machine capacity constraint so as to minimize the sum of stocking costs and changeover costs .
