由于制造轮辐的板材是不定尺寸的,而生产不同品种的钢圈,又是使用同一种板材。如果采用线性规划合理排料,便可以充分利用钢材和降低生产成本。板材一般都是长方形的,而轮辐的坯料都是正方形的,如果采用图1所示的排料方案,即使再省料,也是不适用的,因为这样无法在剪床上剪切。如果采用图2所示的排料方案, As the manufacture of spokes of the plate is not the same size, and the production of different varieties of steel ring, but also use the same plate. If you use linear programming reasonable discharge, you can take full advantage of steel and reduce production costs. The plates are generally rectangular, and the spoke blank are square, if the use of the discharge plan shown in Figure 1, save even if the material is not suitable, because it can not be cut in the shear bed. If you use the discharge plan shown in Figure 2,
