A New Dantzig-Wolfe Reformulation And Branch-And-Price Algorithm For The Capacitated Lot Sizing Problem With Set Up Times
Degraeve, Degraeve, Z.; Jans, Jans, R.F. - Erasmus Research Institute of Management (ERIM), … - 2003
The textbook Dantzig-Wolfe decomposition for the Capacitated Lot Sizing Problem (CLSP),as already proposed by Manne in 1958, has an important structural deficiency. Imposingintegrality constraints on the variables in the full blown master will not necessarily give theoptimal IP solution as only...

Combining economic and social goals in the design of production systems by using ergonomics standards
Dul, Jan; de Vries, de Vries, H.J.; Verschoof, Verschoof, S. - Erasmus Research Institute of Management (ERIM), … - 2004
In designing of production systems, economic and social goals can be combined, if ergonomics is integrated into the design process. More than 50 years of ergonomics research and practice have resulted in a large number of ergonomics standards for designing physical and organizational work...

Modeling Industrial Lot Sizing Problems: A Review
Jans, R.F.; Degraeve, Z. - Erasmus Research Institute of Management (ERIM), ERIM … - 2005
In this paper we give an overview of recent developments in the field of modeling single-level dynamic lot sizing … problems. The focus of this paper is on the modeling various industrial extensions and not on the solution approaches. The … and the research basically expands in two opposite directions. The first line of research focuses on modeling the …

A Geometric Algorithm to Solve the Ni/G/Ni/Nd Capacitated Lot-Sizing Problem in O(T^2) Time
van den Heuvel, Wilco; Wagelmans, Albert P. M. - 2010
In this paper we consider the capacitated lot-sizing problem (CLSP) with linear costs. It is known that this problem is NP-hard, but there exist special cases that can be solved in polynomial time. We derive a backward algorithm, based on the forward algorithm by Chen et al. (1994), to solve the...

Improved Lower Bounds for the Capacitated Lot Sizing Problem with Set Up Times
Degraeve, Zeger; Jans, Raf - 2012
We present new lower bounds for the Capacitated Lot Sizing Problem with Set Up Times. We improve the lower bound obtained by the textbook Dantzig-Wolfe decomposition where the capacity constraints are the linking constraints. In our approach, Dantzig-Wolfe decomposition is applied to the network...

Polynomial Time Algorithms for Some Multi-Level Lot-Sizing Problems with Production Capacities
van Hoesel, Stan; Romeijn, H. Edwin; Romero Morales, Dolores - 2012
We consider a model for a serial supply chain in which production, inventory, and transportation decisions are integrated, in the presence of production capacities and for different transportation cost functions. The model we study is a generalization of the traditional single-item economic...

Determining the Optimal Order Picking Batch Size in Single Aisle Warehouses
Le-Duc, Tho; de Koster, M. B. M. - 2013
This work aims at investigating the influence of picking batch size to average time in system of orders in a one-aisle warehouse under the assumption that order arrivals follow a Poisson process and items are uniformly distributed over the aisle's length. We model this problem as an M/G[k]/1...

Economic Lot-Sizing Games
van den Heuvel, Wilco; Borm, Peter; Hamers, Herbert - 2010
In this paper we introduce a new class of OR games: economic lot-sizing (ELS) games. There are a number of retailers that have a known demand for a fixed number of periods. To satisfy demand the retailers order products at the same manufacturer. By placing joint orders instead of individual...
