Abstract:This paper deals with the Two-Dimensional Cutting Stock Problem with Setup Cost (2CSP-S). This problem is composed of three optimization sub-problems: a 2-D Bin Packing (2BP) problem (to place images on patterns), a Linear Programming (LP) problem (to find for each pattern the number of stock sheets to be printed) and a combinatorial problem (to find the number of each image on each pattern). In this article, we solve the 2CSP-S focusing on this third sub-problem. A genetic algorithm was developed to automatic… Show more
“…In Bonnevay, Aubertin and Lazert (2015) and Bonnevay, Aubertin and Gavin (2015), a well-known algorithm (see Section 3.1) and a classical linear programming solver were used to solve the sub-problems (i) and (ii). And to solve the sub-problem (iii), paper by Bonnevay, Aubertin and Lazert (2015) proposes a simulated annealing algorithm (SA-2CSP-S) and paper by Bonnevay, Aubertin and Gavin (2015) proposes a genetic algorithm (GA-2CSP-S).…”

“…To create the initial solution of the simulated annealing algorithm in Bonnevay, Aubertin and Lazert (2015) or the initial population of the genetic algorithm in Bonnevay, Aubertin and Gavin (2015), a feasible solution should be generated. The first step of our process is inspired by Imahori et al (2003).…”

This paper deals with the two-dimensional cutting stock problem with set-up cost (2CSP-S). This problem is composed of three optimisation sub-problems: a 2-D bin packing (2BP) problem (to place images on patterns), a linear programming (LP) problem (to find for each pattern the number of stock sheets to be printed) and a combinatorial problem (to find the number of each image on each pattern). We have already developed two different metaheuristics to solve the 2CSP-S focussing on this third sub-problem: a simulated annealing and a genetic algorithm. In this article, we propose to compare these two approaches. It is important to notice that our approaches are not new packing techniques. This work was conducted for a paper industry company and experiments were realised on real and artificial data sets.
