Genetic algorithm, MIP and improvement heuristic applied to the MLCLP with backlogging
(2013-08-21)
The present paper solves the multi-level capacitated lot sizing problem with backlogging (MLCLSPB) combining a genetic algorithm with the solution of mixed-integer programming models and the improvement heuristic fix and ...

A priori reformulations for joint rolling-horizon scheduling of materials processing and lot-sizing problem
(2013-06-10)
In many production processes, a key material is prepared and then transformed into different final products. The lot sizing decisions concern not only the production of final products, but also that of material preparation ...
Strategies to model scheduling decisions to plan the soft drink production process
(2012-06-13)
In this paper we present a mixed integer model that integrates lot sizing and lot scheduling decisions for the production planning of a soft drink company. The main contribution of the paper is to present a model that ...

Comparison of mip models for the integrated lot-sizing and one-dimensional cutting stock problem
(2016-01-01)
Production processes comprising both the lot-sizing problem and the cutting stock problem are frequent in various industrial sectors. However these problems are usually treated separately, which can generates suboptimal ...
A Lagrangian relaxation approach to a coupled lot-sizing and cutting stock problem
(Elsevier B.V., 2009-06-01)
Industrial production processes involving both lot-sizing and cutting stock problems are common in many industrial settings. However, they are usually treated in a separate way, which could lead to costly production plans. ...
Joint rolling-horizon scheduling of materials processing and lot-sizing with sequence-dependent setups
(Springer, 2007-08-01)
A lot sizing and scheduling problem from a foundry is considered in which key materials are produced and then transformed into many products on a single machine. A mixed integer programming (MIP) model is developed, taking ...

A Hybrid Heuristic Approach to Solve the Multi Level Capacitated Lot Sizing Problem
(Ieee, 2011-01-01)
This paper presents preliminary results found by a hybrid heuristic applied to solve the Multi-Level Capacitated Lot Sizing Problem (MLCLSP). The proposed method combines a multi-population genetic algorithm and fix-and-optimize ...
