GUEVARA-PALMA, Luis et al. Fitting Irregular Shape Figures into Irregular Shape Areas for the Nesting Problem in the Leather Industry. Ing. invest. y tecnol. [online]. 2015, vol.16, n.1, pp.25-34. ISSN 2594-0732.

The nesting problem of irregular shapes within irregular areas has been studied from several approaches due to their application in different industries. The particular case of cutting leather involves several restrictions that add complexity to this problem, it is necessary to generate products that comply with the quality required by customers This paper presents a methodology for the accommodation of irregular shapes in an irregular area (leather) considering the constraints set by the footwear industry, and the results of this methodology when applied by a computer system. The scope of the system is to develop a working prototype that operates under the guidelines of a commercial production line of a sponsor company. Preliminary results got a reduction of 70% of processing time and improvement of 5% to 7% of the area usage when compared with manual accommodation.

Keywords : nesting; cutting leather; program; software; system of production.
