【摘要】 为降低企业入厂物流成本,以最小化运行成本为目标,将直送、越库和循环取货3种入厂物流运输模式拓展到多供应商、多制造商(n-n)的研究空间,建立入厂物流运输方案规划问题的非线性整数规划模型并使用模拟退火算法进行求解。该算法中解的表示方法采用了综合循环取货与越库的m×n矩阵编码方法,并设计了基于3种变异操作的邻域选择方法。最后的算例验证了算法的有效性及使用该方法设计的运输方案所具有的显著优越性。更多还原

【Abstract】 To reduce inbound logistic cost of enterprises, aiming at minimizing running costs, three kinds of inbound logistic transportation modes: the direct transportation mode, the cross-dock transportation mode, and the milk-run transportation mode, were applied to the multi-suppliers and multi-manufactures(n-n) inbound logistic transportation problem. Then, the respective non-linear integer programming model was built and solved by simulated annealing algorithm. The solution coding scheme in this algorithm was m×n matrix coding scheme combining with the milk-run and the cross-dock. And the neighborhood selection process was designed based on three mutation operations. Finally, numerical examples verified the significant advantages of the proposed programming method and the validity of this proposed algorithm.更多还原
