Mathematical model for twodimensional parts clustering of special shapes

This paper works out in detail the mathematical model for the problems of two dimensional parts clustering on the area of given dimensions, which occur in cutting of materials in metal working industry. Mathematical model solves problems of distributing elements in shapes of: polygon, circle, elipse, hyperbole, parabola and complexed forms, which present the combination of those shapes, on the area of given dimensions. The minimal material expenditure is taken as the optimuzation criterion.
