Solving a multi-level capacitated lot sizing problem with multi-period setup carry-over via a fix-and-optimize heuristic
Sahling, Florian; Buschkühl, Lisbeth; Tempelmeier, Horst; … - 2008
This paper presents a new algorithm for the dynamic Multi-Level Capacitated Lot Sizing Problem with Setup Carry-Overs (MLCLSP-L). The MLCLSP-L is a big-bucket model that allows the production of any number of products within a period, but it incorporates partial sequencing of the production...

An O(Tˆ3) algorithm for the capacitated lot sizing problem with minimum order quantities
Okhrin, Irena; Richter, Knut - 2010
This paper explores a single-item capacitated lot sizing problem with minimum order quantity, which plays the role of minor set-up cost. We work out the necessary and suffcient solvability conditions and apply the general dynamic programming technique to develop an O(T³) exact algorithm that is...

A note on capacitated lot sizing with setup carry-over
Briskorn, D. - 2004
The "Capacitated lot sizing problem with setup carry-over" is based ort the well known "Capacitated lot sizing problem" and incorporates the possibility of preserving a setup-state from a period to the following. Sox and Gao [2] decompose their formulation of the first one (GCLP1) by Lagrangian...

Local search for nonpreemptive multi-mode resource-constrained project scheduling
Kolisch, Rainer; Drexl, Andreas - 1994
This paper addresses a general class of nonpreemptive resource-constrained project scheduling problems in which activity durations are discrete functions of committed renewable and nonrenewabe resources. We provide a 0-1 problem formulation and stress the importance of the outlined model by...

Input use and capacity constraint under uncertainty: The case of irrigation
Bontems, Philippe; Favard, Pascal - 2002
In this paper we consider a two periods model of cropping using irrigation. The farmer takes two kind of decisions, one related to the level of investment in irrigation capacity and the other one to the irrigation level in each period. In the first period, decisions are taken under uncertainty...

Carbon Leakage and capacity-based allocations: Is the EU right?
Meunier, Guy; Ponssard, Jean-Pierre; Quirion, Philippe - 2012
Two main approaches have been implemented in regional CO2 markets to address competitiveness and carbon leakage: output based allocation (Australia, California, New Zealand) and capacity based allocation (EU). This paper characterizes the best policy, given that auctioning with border adjustment...

Capacity constrained price competition and entry deterrence in heterogeneous product markets
Schulz, Norbert - 1999
In this paper three issues are pursued. First, a model of capacity constrained price competition is suggested. The basic feature of this model is that a pure strategy equilibrium exists for all price subgames. Second, this permits Cournot outcomes in heterogeneous markets to be interpreted as...

Dynamic capacitated lot sizing with random demand and dynamic safety stocks
Helber, Stefan; Sahling, Florian; Schimmelpfeng, Katja - 2011
We present a stochastic version of the single-level, multi-product dynamic lotsizing problem subject to a capacity constraint. A production schedule has to be determined for random demand so that expected costs are minimized and a constraint based on a new backlog-oriented -service-level measure...
