Nesting Algorithms for Placement of Regular & Irregular Shaped Parts: A Review

Nesting problem is of great interest to garment, paper, furniture, marble tiles, glass, ship building and sheet metal industries since small improvement of layout can lead to large savings in material. Many effective solutions have been proposed for the case when pieces and containing region are both rectangular. Two dimensional irregular-shaped nesting problems is the problem of finding an efficient arrangement for pieces in a containing region without overlapping, and is aimed at maximizing use of material. This paper systematically reviews the nesting algorithms that were developed to perform various 2-dimensional nesting tasks, and attacks the regular and irregular part nesting problem.
