Problem type: MIP (medium)

Description: Lot-sizing problems are production planning problems in which the periods are a priori, and production of an item in a given period implies some discrete event such as payment of a cost or the loss of a amount of production capacity, due to placement of an order, or the set-up, startup, or changeover of a machine. This is an multi-item, multi-level lot-sizing problem.
