Lagrangian heuristic for a class of the generalized assignment problems
(Pergamon-Elsevier B.V. Ltd, 2010-08-01)
A Lagrangian based heuristic is proposed for many-to-many assignment problems taking into account capacity limits for task and agents. A modified Lagrangian bound studied earlier by the authors is presented and a greedy ...

Transmission Expansion Planning Via a Constructive Heuristic Algorithm in Restructured Electricity Industry
(Ieee, 2013-01-01)
The transmission expansion planning problem in modern power systems is a large-scale, mixed-integer, nonlinear and non-convex problem. this paper presents a new mathematical model and a constructive heuristic algorithm ...
Mathematical models and a heuristic method for the multiperiod one-dimensional cutting stock problem
(2016-03-01)
The multiperiod cutting stock problem arises in the production planning and programming of many industries that have the cutting process as an important stage. Ordered items are required in different periods of a finite ...
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 ...
Simple heuristics for the assembly line worker assignment and balancing problem
(SpringerThe Netherlands, 2012)
We propose simple heuristics for the assembly line worker assignment and balancing problem. This problem typically occurs in assembly lines in sheltered work centers for the disabled. Different from the well-known simple ...

Simple and efficient heuristic approach for the multiple-depot vehicle scheduling problem
(SPRINGER VERLAG, 2016-10-01)
In this paper, a fast heuristic approach is proposed for solving the multiple depot vehicle scheduling problem (MDVSP), a well-known NP-hard problem. The heuristic is based on a two stage procedure. The first one applies ...
