A genetic algorithm method is applied to solve the optimal arrangement of defect stone slab so as to improve the utilization of stones. As far as the optimal arrangement of large stone slabs, which have defects, is concerned, a solution is offered and a mathematical model is established based on genetic algorithm. The programming for singular arrangement of defect stone slab is developed with C# and it is combined with Auto CAD. The program module is set up. The result shows that the optimum arrangement of defect stone slab can be obtained by genetic algorithm method and parameter design also can be finished with developed program. The design of slab and collection of surface data are connected effectively and on - line measure and optimum cutting can be realized. Slabs with defects, such as holes and large stain on the slabs can be avoided when cutting with the method. The utilization rate of slabs is greatly promoted by the method and program. It can solve the problem well in the singular optimal arrangement of defect stones.
