Solution for textile nesting problems using adaptive meta-heuristics and grouping

Abstract

 An optimal packing problem of non-convex polygons on a sheet is considered and applied to a textile nesting problem. We propose a procedure of grouping objects and adaptive meta-heuristics. The grouping procedure classifies objects into groups which are then allocated on the sheet using adaptive meta-heuristics. As a result, effectiveness of the meta-heuristics is improved. The performance of the proposed method is compared with other meta-heuristics using simulation experiments. The result shows that the present method is superior to cases where adaptive meta-heuristics without grouping are used.
