A Lagrangian relaxation approach to a coupled lot-sizing and cutting stock problem
(Elsevier B.V., 2014)
Reformulation and a Lagrangian heuristic for lot sizing problem on parallel machines
(Springer, 2014-06-01)
We consider the capacitated lot sizing problem with multiple items, setup time and unrelated parallel machines. The aim of the article is to develop a Lagrangian heuristic to obtain good solutions to this problem and good ...
Calculating the Best Dual Bound for Problems with Multiple Lagrangian Relaxations
(Maik Nauka/interperiodica/springer, 2010-12-01)
There are often many ways in which a given problem can be relaxed in a Lagrangian fashion. It is not obvious a priori, which relaxation produces the best bound. Moreover, a bound may appear to be the best for a certain ...

An active/reactive predispatch model incorporating ramp rate constraints solved by dual decomposition/lagrangian relaxation
(2004-12-01)
The Predispatch model (PD) calculates a short-term generation policy for power systems. In this work a PD model is proposed that improves two modeling aspects generally neglected in the literature: voltage/reactive power ...
