    摘要:

    在分析具有條狀結(jié)構(gòu)特點(diǎn)的二維斬?cái)嗲懈畈季忠延心Ｐ蛢?yōu)缺點(diǎn)的基礎(chǔ)上,，提出了具有條塊結(jié)構(gòu)特點(diǎn)的斬?cái)嗲懈畈季址桨敢约盎跅l塊結(jié)構(gòu)的斬?cái)嗲懈顔l(fā)性規(guī)則，建立了相應(yīng)的優(yōu)化模型和算法。條塊結(jié)構(gòu)方案較條結(jié)構(gòu)及其他結(jié)構(gòu)方案切割結(jié)構(gòu)簡單，并具有較好的計(jì)算結(jié)果。經(jīng)過實(shí)例計(jì)算,，證明了模型和算法的有效性。

    Abstract:

    The strong and weak points of the guillotine cutting stock problem based on strip patterns were analyzed. New guillotine cutting patterns with “strip block” characteristics and corresponding heuristic rules have been put forward. The model and heuristic algorithm were also presented. Strip block patterns kept the simple 3 staged cutting and were easy to reach better optimization results when compared with strip patterns and other ones. Computational testing instances were taken from Morabito, Scheithauer and Hifi. The testing results showed the effectiveness of this approach through comprehensive comparison and analyses.
