An effective solution for a real cutting stock problem in manufacturing plastic rolls

Ramiro Varela, Camino R. Vela, Jorge Puente, María Sierra, Inés González-Rodríguez
2008 Annals of Operations Research  
We confront a practical cutting stock problem from a production plant of plastic rolls.  ...  To do that, we propose a Sequential Heuristic Randomized Procedure (SHRP).
