| Abstract: | Shown is the effect of setup time on lot sizing. The setting is the Capacitated Lot Sizing Problem, the single machine lot sizing problem with nonstationary costs, demands, and setup times. A Langrangian relaxation of the capacity constraints allows it to be decomposed into a set of uncapacitated single product lot sizing problems. The Langrangian dual costs are updated and the single-item problems are solved by dynamic programming. The algorithm solves larger problems better than smaller problems, although they are more time consuming to solve. |
