friable rock

The heuristic algorithm takes into account the loading mass,the loading capacity,the center of gravity of the load,the situation,for example,direction in which the goods are placed,and the character that if goods are fragile or not.

基于集装箱运输托运人的立场,考虑了实际中集装箱装载常遇到的问题,以集装箱的最大载重、容积、重心稳定性和货物易碎与否、放置状态特征等作为约束条件,并以最大化托运人的运营收益为最终目标,建立数学模型,设计了一种启发式算法,通过算例进行验证,取得了较好的结果。
