Comparison of Lagrangian Bounds for One Class of Generalized Assignment Problems
(Maik Nauka/interperiodica/springer, 2008-05-01)
Classical and modified Lagrangian bounds for the optimal value of optimization problems with a double decomposable structure are examined. For the class of generalized assignment problems, this property of constraints is ...

A Lagrangian bound for many-to-many assignment problems
(Springer, 2010-04-01)
A simple procedure to tighten the Lagrangian bounds is proposed. The approach is interpreted in two ways. First, it can be seen as a reformulation of the original problem aimed to split the resulting Lagrangian problem ...

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 ...
Optimal control problem for deflection plate with crack
(Springer/plenum Publishers, 2012-07-01)
We consider a control problem where the state variable is defined as the solution of a variational inequality. This system describes the vertical displacement of points of a thin plate with the presence of crack inside ...

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 ...
