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 ...

The problem of scheduling production in an unrelated parallel machine environment is recurrent in manufacturing companies with machines that can produce the same products at different and unrelated times. Optimization ...

In this paper, a method for solving the short term transmission network expansion planning problem is presented. This is a very complex mixed integer nonlinear programming problem that presents a combinatorial explosion ...

Production planning and scheduling for sawmills poses many challenges. The solution approaches most commonly used to tackle this problem in the forest industry are: simulation, mathematical programming models, and a ...

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 ...
