摘要
(1)Based on the relationship between the left bottom corner coordinate of the rectangles and the unit of the stripe box, a more efficient linear integer programming model for the 2D rectangular strip packing problem (2DR-SPP) with non-rotating rectangles is established, in which the behavior of forbidding two rectangles placed with overlap is guaranteed. In the rotatable 2DR-SPP, every rectangle is placed to the stripe box only with the way of rotated 900 or not, and the feature is utilized to build the mathematical model of the rotatable 2DR-SPP based on the not rotated problem. The effectiveness and accuracy of two models are demonstrated by the results of computational experiments.
