Journal ArticleDOI
Lot sizing and furnace scheduling in small foundries
TL;DR: In this paper, a relax-and-fix (RF) approach is developed that can also be used on a rolling horizon basis where only immediate-term schedules are implemented, and three variants of local search method are also developed and tested using instances based on the literature.
Journal ArticleDOI
Joint rolling-horizon scheduling of materials processing and lot-sizing with sequence-dependent setups
TL;DR: A mixed integer programming (MIP) model is developed, taking into account sequence-dependent setup costs and times, and then adapted for rolling horizon use, and a relax-and-fix solution heuristic is proposed and computationally tested against a high-performance MIP solver.
Journal ArticleDOI
Classification and literature review of integrated lot-sizing and cutting stock problems
TL;DR: A deterministic mathematical model, that considers multiple dimensions of integration and comprises several aspects found in practice, is proposed and used as a framework to classify the literature related to the integration between the lot-sizing and cutting stock problem.
Journal ArticleDOI
Mathematical models and a heuristic method for the multiperiod one-dimensional cutting stock problem
TL;DR: In this article, a multi-period cutting stock problem is considered in the production planning and programming of many industries that have the cutting process as an important stage and a residual heuristic is used.
Journal ArticleDOI
The integrated lot sizing and cutting stock problem with saw cycle constraints applied to furniture production
TL;DR: An integrated mathematical model is proposed that includes lot sizing decisions with safety stock level constraints and saw capacity constraints taking into account saw cycles and performs well, both in terms of reducing the total cost of raw materials as well as the inventory costs of pieces.
